Locomotive update

It has now been nearly two years since I started building and converting locomotives to battery power and radio control and in that time, a lot has happened. I feel it is now about time I presented updated and collated information about developments in the motive power on the railway.


Locomotive No. 1 - "Peckforton" - Peckett 0-4-0

This was constructed from a Garden Railway Specialists kit in 2008 (see How I constructed a Peckett loco). Seven years ago, GRS kits were largely made from preformed Plasticard plus whitemetal fittings. The kits have now improved with fewer cast resin parts in place of the plasticard pieces.

The body was mounted on an LGB 0-4-0 Toytrain chassis which, considering it was secondhand when I bought it, served me well until the start of this year. After converting it to battery power (see below) and radio control, I gave it a load test which it handled well, until it ran into an obstacle on the track. This proved too much for the nylon worm wheels which admitted defeat and stripped themselves of teeth. Fortunately, I had a brand new ToyTrain motor block to hand and this was pressed into service.

She is now powered by three 18650 lithium-ion batteries which are housed in the cab (see Converting a track powered loco to battery power). There would have been sufficient room for them in the saddle tank, but opening-up the tank and removing the lead weights which are firmly glued inside would have required a substantial rebuild.

Control is via a Deltang Rx65b combined receiver/controller, which is the latest innovation from the Deltang stable (for more information see An evaluation of Deltang radio control and Getting started with Deltang r/c in the garden).

As Peckforton was my first purpose-built loco for the railway, I am delighted she is now back in service. However, as you can see from the photos, she lacks refinement. I really need to spend some time adding details and I'd like to replace the ToyTrain cylinders and motion with something more prototypical. At present, she does not have a soundcard and, without freeing-up space in the saddle tank, there is very little room left to instal one. However, she runs well and is very responsive to radio control.

I consider her a mixed traffic loco and so hauls passenger and goods trains. In a test run to answer an enquiry on the Garden Rails forum, she ran continuously for five hours and 20 minutes on one charge of the batteries.

Locomotive No. 2 - "Beeston" - Barclay 2-4-0T

This loco was bought secondhand from GRS in 2010 (see Progress Report 26), having been constructed from one of their very early kits (now no longer available). It is based loosely La Moye, a loco which ran on the Jersey Railway and is now preserved in South Africa.

She has an LGB motor block and Walschaerts valve gear presumably from another LGB locomotive (such as the Zillertalbahn U class loco). It was converted from track power to battery radio control in 2014 using a Deltang Rx60 receiver/controller (see Progress Report 51).

Other than a coat of paint and Trimline tape lining, she has not been modified or detailed since she arrived on the line, apart from the addition of some cosmetic buffers. I tend use her mostly for passenger duties. She will happily shunt wagons but as the driving wheels are quite large her crawling speed is less controllable than other locos.



Locomotive No. 3 - "Bickerton" - Hunslet 0-4-0T

I constructed this loco from a GRS resin kit and an LGB ToyTrain 0-4-0 motor block in 2010 (see How I constructed a Hunslet loco from a GRS kit). At present, she is still track-powered and so, as I have now sold off all my DCC gear, she is out of action.

The only place to install the batteries would appear to be inside the saddle tank. This will entail some substantial dismantling and rebuilding as the saddle tank is presently crammed full of lead. However, it will be good to see her back in action on the line.

She is in need of detailing and some light weathering.

Update Sept 2015 - She has now been converted to battery power with three 18650 li-ion batteries and a Deltang Rx65 receiver controller

Locomotive No. 4 - "Bulkeley" - Manning Wardle 0-6-2T

This was my first scratchbuilt steam loco (see How I constructed a Manning Wardle 0-6-2T loco) and joined the line in 2013. She is based on the Southwold Railway No. 4 loco, Wenhaston. I found that the driving wheel sizes of the LGB U-class 0-6-2T locomotive were the correct size, though the wheel spacings are incorrect - the trailing driving wheels being too close to the centre pair. However, as the motor block included Walschaerts valve gear, I decided I could live with the slight inaccuracy.

 She is controlled by a Deltang Rx60 receiver/controller and powered by a 12v li-ion battery which is intended for use in CCTV cameras. These batteries include protection circuits which monitor charging and discharging.

I decided to leave her unlined, as a homage to the Southwold livery which she wore for most of her working life. As my railway is set in 1932, I argue that they bought the loco from the SR when it closed in 1929. I will probably add some finer details at some point in the future, but for now she will happily pull passenger or goods stock.


Locomotive No. 5 - "Tarporley" - Sharp Stewart 2-4-2T

My second scratchbuilt steam loco was somewhat more ambitious as, not only did she have leading and trailing pony trucks, I also had to construct her motion (see How I constructed a Sharp Stewart 2-4-2T loco). She was constructed during 2013 and is based on the second Southwold Railway No. 1 loco, Southwold.



 Motive power comes from a PlayMobil 0-4-0 motor block as I found the wheel sizes and spacing were approximately correct for 16mm:1foot scale. She is powered by a 12v li-ion CCTV camera battery and controlled by a Deltang Rx60 receiver/controller.

Once the loco was finished, I spent a while adding smaller details, such as the oiling pots. She also has works plates which I feel add an extra touch of realism.


Locomotive No. 6 - "Harthill" - Manning Wardle 0-6-0ST

My third scratchbuilt steam loco was completed in 2014 (see How I constructed a Manning Wardle 0-6-0ST loco). She is based on the Manning Wardle locos which ran on the 3'6" gauge railway at Davington. These were shipped to Brazil when the railway closed at the end of World War I. I found this loco to be the most challenging of the three to construct, owing to the saddle tank and making sure there was sufficient space inside the body to accommodate three 18650 lithium-ion batteries. She also has a fair amount of external pipework which proved to be more complicated to construct than it might appear.

 Motive power is provided by a Piko 0-6-0 motor block, which I've found to be a delight. It is extremely smooth running, especially at low speed, and is very responsive to the Deltang Rx65a receiver/controller.

She is in unlined livery and has recently been given appropriately number works plates. She has become the stalwart of the line, handling goods and passenger traffic with alacrity. Out of curiosity, I gave her a haulage test and found she could pull 24 wagons up a 1:40 gradient with ease.



Locomotive No.7 - "Tollemache" - Fowler 0-4-0DM

 This was my first foray into scratchbuilding in 2011 (see How I constructed a Fowler diesel loco). Based on an LGB ToyTrain 0-4-0 motor block, she is based loosely on the early Fowler diesel mechanical locomotives which ran on standard gauge and narrow gauge railways. Whilst I could find photos of standard gauge and 2' narrow gauge locos, I couldn't find an image of a 3' gauge Fowler and so imagined how it might look.

At present, she is still track-powered, but will be the next loco to be converted to battery operation. The flycranks on the layshaft are, at present, somewhat loosely connected to the driving wheels, as I was unable to source flycranks of the correct size and so overcame this by slotting the holes in the connecting rod. When converted, I will improve this aspect and also add some finer detailing.

Locomotive No.8 - "Wynford" - Freelance 0-4-0DM

This was my second venture into battery power and, like my first battery model (see below), has had a long and chequered history. After three failed attempts to construct a reliable mechanism, I eventually found success by inserting a USA Trains motor block into the chassis. This lengthened the wheelbase, but has proved to be a lot more reliable than any of the previous mechanisms.

 The bodywork is from an IP Engineering Jessie kit (now no longer available) which, being constructed principally from steel, provides plenty of inherent weight. As a consequence, I have not had to add any additional weight and yet she will happily haul twenty skips up the 1:40 gradients on my railway. She was originally powered by ten NiMh batteries but these have just been replaced by three 18650 li-ion batteries with a protection board. She is controlled via a Deltang Rx102 receiver feeding into a Brian Jones Mac5 ESC. Because the original mechanisms were so unreliable, I found that trying to control her with a Deltang Rx60 receiver/controller was somewhat erratic. I assume this is because this particular receiver was limited to 1 amp loading and the mechanisms might have been drawing more current (and were probably creating all manner of electromagnetic interference). One day, I will try controlling her with the more recent Deltang Rx65b - which can handle up to 3 amps.

She has a Peter Spoerer DigiSounds narrow gauge diesel sound module (developed by Mktroniks) which, as the name suggests, uses digitised recordings of a real diesel engine, and so sounds rather impressive.

Locomotive No. 9 - "Lolly"- Freelance 'Lollypop' railcar

 Constructed from an IP Engineering kit (see How I constructed a small railcar from an IP Engineering kit),

...... this diminutive railcar was constructed as an experiment to find out how responsive Deltang receivers would be with a low voltage supply - three NiMh Low Self Discharge (LSD) batteries = 3.6v (see Evaluation of Deltang with low voltages). In fact, as Deltang receivers actually step down input voltages to 3v, they will happily manage with these low voltage supplies. This model uses a Deltang Rx60 receiver.

 I added additional detailing (ie planking and bracing) during construction and she has red/white bi-colour LEDs which change colour dependent on direction of travel. She acts as the railway's permanent way vehicle and has a small trailer wagon which is often attached for the workers' tools (see How I constructed a small PW flat wagon).

'Locomotive' No. 10/10a - "Samantha" & "Josephine" - Freelance Ford(ish) railmotors

This was my first major investigation into the feasibility of battery power and radio control and as with No. 8 the railmotors went through various control systems and mechanisms before reaching their present state. They were 'bashed' from two freelance Andel resin coach kits (see How I bashed two Andel coaches into a 'Ford' railmotor) and the power car is now powered by a 12v CCTV li-ion battery, controlled by a Deltang Rx60 receiver/controller and motorised with a MFA Como gearbox motor and bevel gears.

For a while, they were extremely unreliable, becoming derailed when encountering any slight undulation in the track. Eventually, I created a very simple form of compensation on the leading axle of each car and since then have had very few derailments even though they are somewhat top-heavy.

  Both cars have operating directional headlights and internal lighting.

At present they do not have a sound card but I am experimenting with various methods of digitising the sound effects of a Model T Ford starting, stopping and running at speed using a small sound recording board controlled by a Picaxe chip.

Locomotive No. 11 - "Linda" - Freelance 0-4-0DM

This was my first venture into 32mm gauge and was bought for a relatively modest sum on eBay. She has an IP Engineering body on an HGLW chassis. She was originally manually controlled and powered by two AA alkaline non-rechargeable batteries. These were replaced by a single 185650 li-ion battery and a Deltang Rx65b receiver/controller was installed.

The receiver has been programmed to operate in shuttle mode as I decided it would be useful to have her pottering backwards and forwards with a train of Binnie skip wagons while I operated the main railway.

At present, she is more or less in the condition I bought her, but I have added more a little more detailing and given her some light weathering. It is doubtful I will add a sound card as space is limited, however, I am experimenting with a couple of small sound modules which are used in greetings cards to see if something could be squeezed in somewhere.

Locomotive No. 12 - "Emma" - Plate frame Simplex

 Constructed from an IP Engineering kit, at present she is powered by two 14500 li-ion batteries and manually controlled with a Deltang Rx65b receiver controller (see How I constructed a plate frame Simplex from an IP Engineering kit)



She has also been fitted with a small soundboard which has been modified from a cheap (£1.29) module designed to be used in musical greetings cards. While the sound isn't quite hi-fi, it is quite adequate for this little loco.

She is dual gauge - with interchangeable 32mm and 45mm gauge chassis. Both chassis have been fitted with chain drive which makes her quite a powerful little loco for her size

Progress Report 49

This year has so far been quite eventful on the Peckforton Light Railway. I have spent a fair bit of time and money exploring the feasibility of battery power for the railway. My aim has been to construct a complete roster of battery powered locos to be able to run an operating session.

So far I have constructed four battery powered vehicles:

A railbus, based loosely on the early Ford railmotors which ran on light railways in the 1920s. She now has an MFA Como gearbox motor, a 12v li-ion battery and a Deltang receiver/controller.

She works well now, although the gears do make a fair bit of racket. However, as it actually sounds a bit like an early Model T Ford engine I'm quite happy! (See How I constructed a railmotor)

An 0-4-0 diesel loco (now christened Wynford). This was constructed from an IP Engineering kit (Jessie) but I've replaced the original gearbox with one using 00 locomotive metal gears. (See How I constructed an IP Engineering diesel) Hopefully it will last a bit longer than the original plastic geared version.

She has 10 x AA NiMh batteries, a Deltang receiver and a Brian Jones Mac Five receiver. She has also recently had a sound card added (see below).

An 0-6-2 Manning Wardle steam loco (No. 4 Bulkeley) based on the Southwold Railway No.4 Wenhaston.

She is based on an LGB motor block (from a U-Class loco), with a 12v li-ion battery and a Deltang receiver/controller. (See How I constructed an 0-6-2T loco)

She is a very smooth and responsive loco - currently the pride of the line. She too has recently had a sound card fitted (see below).

 A petrol driven platelayer's trolley, based on an IP Engineering kit (Lollypop Railcar - See How I constructed an IP Engineering railcar).

This has a 3-6v motor, 4 x AA NiMh batteries and a Deltang receiver/controller. I've not yet added a sound card to this model but am considering something very small and cheap.

A 2-4-2T steam loco based on the second Southwold Railway loco No.1 Southwold (see How I constructed a 2-4-2T loco inspired by a Southwold Railway Sharp Stewart) is presently under construction. Power is provided by an 0-4-0 Playmobil motor-block and, as with the Manning Wardle (see above), the body is constructed from plasticard.

As you can see, she is more or less complete and about to enter the paint-shop. She is powered by a 12v li-ion battey and controlled with a Deltang rx60 receiver/controller. She will also have a MyLocoSound soundcard fitted in the bunker.

Adding sound

Until now I have resisted adding sound to my locos, but as I've become more interested in battery power, it felt like a natural progression. I started first with the diesel loco and invested in a Digisounds card from Peter Spoerer (see How I added a diesel sound card to Wynford).


Having found this experience rewarding, I decided to try adding a steam MyLocoSounds card to the 0-6-2T loco.

What I like about this sound card is that the volume of the sound varies dependent on whether the loco is accelerating or decelerating. The only issue is trying to sychronise the beat of the cylinders to the speed of the loco.

Rationalising resources

To fund these developments, I decided it was time to rationalise some of the gear I had accumulated over time. As I am intending to move over to battery operation, I felt the track cleaning loco was an unnecessary extravagance. As these have risen in price since I bought to over £600 to buy new, I hoped I would recoup the money which I paid for it when I bought it secondhand.

It realised over £350 which was slightly more than I paid for it and so this added substantially to the battery loco kitty.

I also decided to pass on the Jigstones moulds which had been bought for me several Christmases ago. I had used some of them to mould some blocks but decided that there was actually very little space on my railway for more buildings and so, before they deteriorated with age, I decided they needed to be passed on to someone who would make better use of them.

How I added MyLocoSound to a battery powered steam loco

The latest version of the MyLocoSound card was bought from Peter Spoerer. This version incorporates 'coasting' which senses when the loco is accelerating and decelerating and adjusts the volume of the chuff accordingly.

A wire was soldered to pad 6 of the Deltang rx61-22 receiver/controller. This pad is controlled by the bind button on the Tx22 transmitter and will be used to operate the sound card's whistle.

 Because the sound card needs the input for the whistle to be connected to ground (-ve) to trigger the sound and the output from the receiver/controller is 3v (+ve), I constructed a simple transistor switch using the guidance provided on the Deltang website (see How I constructed a simple transistor switch)

A small 'laptop' speaker (provided by Peter Spoerer) was fixed to the cab roof with a double-sided sticky pad and the wires fed through into the firebox.

The internal bracing between the firebox and the boiler was pared down to accommodate the sound card (the blue/purple wires connect to the speaker and the red/black wires are the switched feed from the battery).

The wires were then connected to the terminal block on the sound card. From top to bottom:
  • speaker wires (x2)
  • spare
  • whistle trigger (from the transistor switch)
  • negative supply (and -ve lead to controller/receiver and to transistor switch)
  • positive supply (and +ve lead to the controller/receiver)

Into the terminal block at the other end of the card went the leads to the motor and the leads from the controller/receiver for the motor and finally the two jumpers were removed from the sound card (for 'other' PWM controller settings).

This wiring diagram should hopefully make the setting-up a little more understandable (click to enlarge):

The chassis was then mounted on to a rolling road and the loco turned on so the sound board could be callibrated using the adjuster pots along the top of the board. From left to right:
  • Whistle volume
  • Whistle tone (from tiny peep to throaty roar)
  • Chuff volume
  • Spare
  • Chuff speed (set to match the wheel speed at max)
  • Chuff start (set to start the chuff when the wheels begin to move)

Something I discovered is (of course) that the start setting and the upper speed differs when the loco is under load and so eventually I decided to find the happy medium between unloaded and loaded settings.  The receiver/controller, switch and board were then slotted into the space for them between the firebox and the boiler ........

 ...... and the loco was taken outside for extensive test-running.

Progress Report 47

An almost unbroken spell of sunshine for around three weeks has led to quite a few running sessions and more than a few spells of continuous running while we've had barbecues or simply lazed in the garden. However, I have also taken the opportunity to finish off a couple of jobs and spend some time trying to sort out others.

Loco No. 4 Bulkeley

As mentioned in Progress Report 46, I have been working steadily on scratchbuilding a body for loco No. 4 - Bulkeley, based loosely on the Southwold Railway No. 4, Wenhaston. This was my first venture into building a steam outline loco but I used the skills I had acquired in building the Fowler diesel and rolling stock such the the cattle wagons to construct her largely from plasticard (see How I constructed an 0-6-2T Manning Wardle locomotive). The build was fairly straightforward though I did run into an unforeseen problem when she developed wheelspin on what seemed like insignificant gradients. I eventually tracked this down to the lower end of the bracket supporting the valve gear which was rubbing on the track. This was solved through the addition of an upper support bracket.

For a while, I was uncertain as to the livery of the original Southwold Railway loco - there seemed to be some ambiguity in the books on the SR which suggested she was lined out in light and dark green and yet the photos of the loco I had unearthed show no evidence of lining. After making an enquiry with the Southwold Railway Trust, I discovered that when delivered from Manning Wardle, she was lined.................

....... but when she entered service she was painted in plain dark green livery which she retained throughout her working life. However, towards the end of her life, her livery faded and her works livery started showing through.

My model has now entered service on the Peckforton Light Railway and for the moment she is sporting the line's livery of Brunswick Green (or in her case, Rover Brooklands Green from a Halford's rattle can aerosol). I am trying to decide whether to line her out in gold as with the line's other locos or whether to leave her unlined as a homage to her Southwold origins. You'll notice that I've positioned the loco's number beneath the nameplate as in her Southwold days.

She also has acquired a bespoke driver, made from oven hardening clay. I wanted to represent a driver or fireman passing over a token or just leaning out to watch the loco's motion. He's reasonably detailed though it looks as if his face has met with an unfortunate collision somewhere down the line.

The loco was my first real venture into battery power and after a few teething troubles I am steadily being won over to this form of power. However, I am also upgrading my DCC powered fleet (see below) to improve their reliability.

Adding DIY Power buffers to DCC locos

As all my track-powered DCC locos are designed around LGB 0-4-0 motor blocks it's inevitable that they experience problems when running slowly over the plastic frogs of pointwork. Last year, I invested in a Massoth Power buffer and added this to one of the locos to evaluate its effectiveness (see Progress Report 37). I was extremely pleased with the outcome and vowed I would equip all my locos with one. Despite its relatively low cost (under £25), having retired, funds are not always readily available and so when I came across an article in the French railway modelling magazine, Voie Libre, explaining how a modeller had added his own power buffers to his 0n30 locos, I researched the subject and found out how it can be achieved for as little as £2.50 per loco (see How I added DIY Power Buffers to my Locos).

 All my track powered locos are now equipped with power-buffers and, because I was hard-pressed to find a suitable location for the buffer in my Fowler diesel, I adopted the technique used in the original article and added the capacitor to the footplate to represent an air cylinder.

Working on the gearbox of the IP Engineering diesel loco

 I spent a day or so trying to build my own gearbox to replace the one supplied with the IP Engineering diesel kit, Jessie (see How I constructed a battery powered diesel from a kit). The gearbox as supplied used plastic gears and after only a very brief period of test running these became stripped of their teeth. I bought what I am hoping are more substantial metal gears from Cambrian Models but found that their 20:1 gears are not a direct replacement as the overall dimensions differ. I therefore attempted to construct my own gear housing from brass.

Whilst this worked to some extent, I found that as soon as even a small load was placed on the loco, the gears slipped (though only in reverse, the mesh was fine as long as the loco only travelled forwards). I am now attempting to construct a more reliable gearbox, building on the knowledge I've acquired so far and drawing on the expertise of a friend who has more metal working experience.

Improving the keyfob control on the railbus

After some interesting discussions on the G Scale Central forum about the merits of using a cheap 12v LCD dimmer unit to control a motor.
 

It seems that the unreliability which I had encountered over the speed control of the motor could be greatly improved through the simple addition of a diode across the output connections - see the excellent online article by Dave Bodnar.

I have disassembled my railbus (see How I constructed a railbus) and have duly wired in the requisite diode.

 At the same time I decided to replace the array of AA battery boxes I had used previously with a single 12v Li-ion battery pack which would take up considerably less room. Unfortunately, the pack which I had bought from China via a well known online auction site ceased to function and so I have been unable to test my newly adapted control board. Furthermore, I am growing increasingly concerned with the IP Engineering gearbox which at 16:1 does not provide sufficient torque to power both cars and I am assuming will ultimately strip its gears (see above). I am therefore investigating an alternative approach to powering this vehicle and will post an update when I feel I have made some progress.

More running sessions

 As indicated above, the weather has provided me with plenty of opportunity to run trains. I have continued to use my original freight handling computer program (see Computerised freight operation)  but have discovered that the freebie software I used to create the freight handling program will not work on Windows 7. I have fortunately found another programming environment which is not only free, it will create standalone programs to run on PC, Mac, tablets and smartphones (Livecode - which is based on the original Mac program - Hypercard). Once I have completed the re-programming I am hoping to be able to distribute various versions for others to use.

In the meantime, here is a small taste of some of the moments drawn from recent operating sessions.
The Down mid morning passenger approaching Bickerton
No. 2 Beeston on the afternoon Up passenger crosses the River Gowy between Peckforton and Beeston Castle
The daily pickup goods arrives at Bickerton with Hunslet No. 3 Bickerton
The pickup goods departs Bickerton on its way up the line towards Bulkeley
Shunting at Bulkeley
No. 3 emerges from the Copper Mine branch running light after delivering a fuel tank wagon
The Up pick-up goods approaching Peckforton where it will cross the Down afternoon passenger
 Now I have managed to sort out the slow running of the locos (see above), I take great delight in relaxing from time to time in a strategically placed garden chair as I watch each train slowly threading its way through the undergrowth from station to station. There is something very satisfying about seeing a train which I have created going about its business.
