Progress Report 56

Now we are entering the winter season, there are fewer opportunities to run trains, but supposedly more opportunities for finishing off construction projects. So far, it has turned out to be more difficult than expected to find time for construction and so progress has been limited. However, there are several projects now on the agenda which I can report on.

Acquisitions

Christmas has come and gone and left me with a couple of additions to the stocklist.

IP Engineering Simplex kit

I have been considering for a while making the feeder from the copper mine to the crushers and loading hopper into a 32mm (2') narrow gauge line (see Progress Report 45). At present it is 16.5mm gauge supposedly representing a 15" gauge railway (but nearer to 13") (see How I constructed some Gn15 skips) and as such it will only ever be cosmetic.

 My thinking was that by having a short stretch of 32mm track, I would have some stock which I could run when I visit other people's garden railways. I am also considering building a simple shuttle control system using a Picaxe micro controller. In the meantime, I now have an IP Engineering Simplex locomotive kit sitting in my 'pending' project box awaiting its turn on the to do list.

Guards' / baggage van

  I saw this on a well known online auction website and considered that the price was sufficiently attractive for it to become an addition to the line. At present, I do not have a dedicated guards' van which could be included in passenger trains and thought this might add more operational interest.

 The van itself has been constructed fairly crudely from plywood and mounted on an LGB chassis. This makes it quite heavy when compared to similar stock. The mouldings are mot particularly crisp and the paintwork is far from smooth. I think it will need some remedial work after being rubbed down in preparation for a repaint.

Also, it is taller than the existing rolling stock and I may consider lowering it on its chassis somehow. This is not a high priority on the todo list and so may languish on the shelves for a while before I decide to deal with it.

Nameplates

I've recently taken delivery of another two etched nameplates from Narrow Planet - my preferred supplier. The former Southwold Railway Sharp Stewart 2-4-2T (see How I constructed a Sharp Stewart 2-4-2T) will become Tarporley and the most recently completed former Davington Light Railway Manning Wardle 0-6-0 will become Harthill (see How I constructed a Manning wardle 0-6-0T). I am following the tradition set by the Southwold Railway of naming locomotives after villages and towns served by the railway.

Also included in the order were some works plates. Two sets of Manning Wardle plates for the former Southwold and Davington LR locos and a set of Sharp Stewart plates for Tarporley.

Jackson Sharp coach bashes

I am making slow but steady progress with these builds. One Open coach has been more or less completed, apart from interior detailing, while the modifications to the underframes and body shells for the remaining Open and the Brake are largely done. 

Open Coach based loosely on the Leek & Manifold coaches

 I still need to complete the roofs, windows, lights, underframe detailing and balconies for these two coaches but, by comparison with the work needed to modify the bodywork, progress should now be a lot swifter.

Progress so far on the Brake End L&M inspired coach

 After reading through some postings on the 16mm NGM forum, I have decided to experiment with printing the stained glass window detailing for the opening lights on to self adhesive acrylic sheet from Crafty Computer Papers.

Deltang radio control equipment upgrades

Since the last update I have constructed a new Tx21 transmitter from a kit and taken delivery of two Rx65b receiver/controllers from Deltang.

I decided to invest in a Tx21 so that when I have visitors there's another controller so we can run trains independently. This was certainly an asset when my Australian friend visited in October (see Progress Report 55).

I was pleasantly surprised at how easy it was to construct the transmitter. The main circuit board was included as a completed unit and all that was required was to drill holes in the case, mount the switches and potentiometer and then solder a few wires from the transmitter chip to the various switches. A few resistors needed to be included in some of the connections but these were relatively easy to solder into place. I'd say the drilling was the most difficult aspect of the build - ensuring the holes were in the right places and correct size.

Over the past couple of years, I have accumulated a range of Deltang receiver/controllers as and when they became available. Some of the early receiver/ESCs were rated only at 1amp which proved to be quite adequate for the LGB motor blocks I was using - but now that the Rx65 3amp receiver/controller has become available, I have decided to standardise.

My most recent loco, the Manning Wardle 0-6-0 has been equipped with one of these receivers and I have been very impressed with its performance. (see Manning Wardle load test video). It seems to be far more responsive and consistent in its smooth running, Whether the Piko 0-6-0 mechanism is responsible or whether the output from the receiver is the major contributory factor remains to be seen - but I will keep readers posted as to progress once the receivers have been installed.

Sound cards

My Australian friend, Greg, came bearing gifts, among which included a few 20 second sound recording chips.

Previously, I have been accumulating the necessary electronic bits and pieces needed to construct my own sound card using a Picaxe chip and a small amplifier. I am intending to follow the guidance given by my Ozzie visitor on his railway's website - http://www.trainweb.org/SaTR/Picaxe%20tutes.htm.

I have also invested in a small sound recording chip similar to those used in greetings cards.

 I am hoping that this will prove small enough to fit inside the Lollypop railcar (see How I Constructed an IP Engineering Railcar)

I still have four locomotives without sound (two steam and two internal combustion) and so, during the coming Spring I intend to construct my own sound systems using a combination of these components. Watch this space for more details.

Track cleaning

One of the great joys I have now is being able to run trains with the minimum of track cleaning and maintenance, compared with that required for operating track-powered locomotives. Recently, after a few weeks with no trains, I decided to have a short running session and was pleasantly surprised at how quickly I could have something up and running compared with the days when I ran only track-powered locos.

Then

Track cleaning preceding a running session used to take a minimum of an hour and on average would take two hours. Once the track had been cleared of debris and encroaching vegetation, I would previously have had to scrub the rail surfaces with an abrasive block and then check for electrical continuity by running a light loco around the track. (see Cleaning the track) If I was lucky, it would manage an entire circuit without stalling. Often, however, there would be a dead spot on the track. This might be caused by the breakdown of the bonding between two lengths of rail (see How I bonded the rails) or could be because the bonding between the rails in the pointwork had deteriorated (see How I improved the electrical continuity of pointwork).

Now

My track cleaning is now a lot more efficient. Clearly, I have to remove debris and overhanging vegetation from the track as before, but that's it. To keep the trackbed reasonably clear, I have taken to sweeping it with a stiff handbrush, which not only removes leaves and branches, it clears away excess moss and encroachment from Mind Your Own Business.

I am hoping for some light snowfall before the end of the winter. Probably because of the hassle associated with using track power, I have, up to now, never taken photos of trains when snow was on the ground. Maybe a light dusting of snow will provide some photo opportunities.

How I constructed some Gn15 skips from Smallbroook kits

Why a 15" gauge feeder?

The copper mines which provide the main rationale for the Peckforton Light Railway are served by a 15" gauge railway system. There is a clear reason for this choice of a 'minimum gauge' feeder line for the Peckforton Railway. In my hypothetical history (see A history of the railway), the local landowner and keen engineer, Lord Tollemache, was the main driving force behind the development of the mines and the railway. I've assumed he would have been very familiar with the 15" gauge Eaton Railway which had been constructed a short distance away from Peckforton on the Duke of Westminster's estate by the pioneer of minimum gauge railways, Sir Arthur Heywood. It seems reasonable that Lord Tollemache would have experimented with a minimum gauge railway to both serve his estate and to negotiate the narrow galleries and tunnels of his copper mines.

The location

Having just completed the buildings for the copper mine (See Progress Report 45) I felt the need to construct a short stretch of Gn15 railway to represent the transportation of the ore and spoil from the mines to the crushing shed and the loading chutes. This, of course, would require some rolling stock. I had previously acquired a loco, a tub and a flat wagon through a well known online auction site but needed to source some appropriate looking skips.

 I had considered making my own but eventually decided I needed the time this would take to devote to other projects on the railway. The most appropriate models seemed to be those provided by Smallbrook Studio. Whilst these are designed for use on 0n16.5 railways, Smallbrook suggests they are equally appropriate for Gn15 - which indeed they are!

Construction

 The kit arrives complete with all fixtures and fittings, and a well explained instruction leaflet.

The resin castings inevitably require some tidying to remove flash, this was achieved with a couple of needle files.

 After suitably sized holes (2.5mm and 0.8mm) were drilled in the ends using the marked centres, brass panel pins were inserted and fixed in place with Superglue for the pivots for the skip .....

 ...... and a suitably bent piece of copper wire was inserted to act as the lifting handle.

 Once the glue had set, the excess was snipped off and filed flat on the inside of the skip tub.

 The two pieces of the chassis were then filed and glued together. The lower half of the chassis is weighted with lead shot which has been embedded in the resin - hence its spotty appearance.

Although the instructions suggest applying the paint at this stage, I decided to add the two squares of plasticard which are provided to make the coupling pockets on the chassis sub-base.

I then filed off the pinpoint bearings on the end of the axles for the wheelsets which again are provided in the kit.

The chassis and the skip tub were then given a couple of coats of Plasticote red oxide primer and then the axle mounts were reamed out with a 2mm drill held in a pin-chuck before the wheels and axles were clipped into place. The couplings were assembled and pushed into the pockets ........

......... and then the wagons were suitably weathered and rusted in my time-honoured way (see How I weathered a set of LGB tippler wagons).

 They have now entered service and, although their use on the railway is purely cosmetic; I am not intending to make the 15" gauge line operational; I do have tentative plans for the construction of a Gn15 indoor railway to represent part of Lord Tollemache's estate and copper mine railway which I can easily imagine wending its way along the Peckforton Ridge. It seems that, once bitten by the railway modelling bug, there's no known cure!

Progress Report 43

This year I have had fewer opportunities than in previous years to run trains on the railway. Firstly, the weather has been very changeable which has meant that there have been relatively few days when an unbroken spell of decent weather could be guaranteed. On a couple of occasions, I had spent an hour or so setting up the railway, only to have to gather everything together and dash back indoors as a shower of heavy rain blew up. Secondly, I have spent several days during the summer period visiting full-scale narrow gauge railways for a new blog which I have set-up (see Narrow Gauge Railways UK). Mostly, these visits seem to have coincided with a spell of decent weather which I could have used for running the railway.

 Thirdly, I have spent quite a bit of the summer, doing running repairs, constructing signals, making a set of buildings for the copper mine and experimenting with radio control (see below).

Running repairs

These have mostly centred on improving the running of stock which had wheels which were incompatible with LGB pointwork (see How I made IP Engineering wheels compatible with LGB pointwork). There would appear to be very little conformity over back-to-back measurements and flange depth of wheels across manufacturers when it comes to 45mm gauge. As a consequence, when products from different suppliers are brought together, there are often problems with smooth running through pointwork. Whilst I have sometimes re-wheeled stock to overcome these difficulties, there are occasions when this is not possible or desirable as, for example, when journals or axle stubs wheel sizes are non-standard. I have developed a rough-and-ready method of beefing-up finer scale wheels to improve their running characteristics through the coarser scale frogs of LGB pointwork.

Another issue associated with LGB pointwork which I have uncovered over the seven years I've been running my railway has been a steady and consistent breakdown in electrical continuity between the running rails, point-blades and lead-rails before and after the frogs. I could have removed every point and soldered invisible connections beneath the rails and sleepers, but when I have done this in the past it has caused more problems than it solved. Consequently, I opted for an in-situ solution of soldering jumper wires from the stock rails to the switch rails.

For more information see - How I repaired LGB pointwork

Constructing signals

As I try to run my railway according to light railway prototypical practices (which of course were often quite idiosyncratic), I decided that with up to three trains in steam at any one time, it was about time I supplied the line with signalling.

Using the signalling diagrams which were provided by a fellow modeller who also happens to be a Railtrack signalman (see Progress Report 36) ........

......... I figured that even the most minimal approach to signalling the railway would require 20 signals (around 4 per station). I explored various kit-built options but decided that the cost would be prohibitive. I had no option but to construct my own signals.

Although the signals were  of the same basic design as I wanted to batch-produce them, there were two alternatives in terms of the types of base. One type had a plate base for mounting on hard surfaces, while the other had a concrete base, for mounting in soft surfaces .......

All the signals are equipped with flickering LED lamps..........

 ....... which are shuttered at the rear.

At present, the signals are operated individually but eventually I hope to have them operated through linkages to a ground frame at each station, as per prototype.

For details of construction see Garden Rail edition 224 (April 2013).

 Mine buildings

Up until now, the sidings for the copper mine have had only a backdrop of the laurel hedge.

Ever since the extension to Beeston Market and the copper mine was constructed (see How I built the extension), I have been planning to add some buildings and loading hoppers.

At this stage, construction is well under way - with a variety of techniques being deployed.

The crusher shed and manager's office

The workshop

 The buildings are still very much work-in-progress with a lot more tidying-up and detailing needed. Once completed, the buildings will include a Gn15 feeder line from the mine workings together with loading hoppers and conveyors. See How I constructed the Mine Buildings)

Radio control

I have been broadening my experiments with battery operation and radio control, following the construction of my first battery powered radio controlled vehicle, a double-ended railbus (see How I constructed a railbus from two Andel coach kits).

A chance-find on eBay resulted in the purchase of a couple of cheap 2.4GHz radio transmitters designed to be used with low-cost helicopters.

I discovered that the transmitters worked with cheap FlySky receivers and so, after setting-up a test-rig, I explored the potential of this cost-effective approach to radio control.

As you can see from the video, with the modest outlay I'm figuring it's worth producing a small fleet of battery-operated locos to run alongside and maybe eventually replace the track powered locos. I have a couple of spare ToyTrain loco blocks which can be pressed into service and one day I will get around to converting my LGB 0-6-2 U-Class Zillertalbahn loco into a representation of the Southwold Railway loco No. 4 Wenhaston.
