Bournahempton [1936 - Southern Railway - 00 - automated]

[jamespetts]

This is a layout that I have been planning since 2018. I may hopefully be able to start building it this year or next.

Background and location

Having enjoyed railway modelling as a child, I had not engaged with this hobby as an adult until about 2018. In that year, I had a shed built in my garden for the purposes of building some layouts. The original plan was to have an 00 gauge layout representing a London terminus set over two levels: the upper level would represent the main line and the lower level would represent the Underground; they would be connected by way of a helix. I then redesigned the 00 gauge layout to represent a terminus on the south coast of England, and removed the underground section. This allowed me to have a different layout on the lower level. I chose to have an N gauge layout set in 1989 on this lower level.

Woodwork is not my forte, so I had the baseboards professionally made. The company that made them recommended that I have the N gauge layout on the lower level built first, as it would be awkward to lay the track to the rear of that layout if the 00 gauge baseboards had already been installed. This I had done, and the boards for this layout were installed in April 2019. Here are some photographs of the shed shortly after the baseboards were installed:

Laying the track on the N gauge layout (which, on the scenic section, was kit built from British Finescale) took longer than I had expected and some time was taken trying to overcome some electrical problems, so I was not ready for the 00 gauge baseboards to be built by the time that the pandemic struck. In any event, the Peco Bullhead slips and crossings required for the 00 gauge layout were not then (and still are not) available. I then focussed my efforts on building the N gauge layout, whose trackwork and electrics are now mostly complete (save for some signals the delivery of which I am still awaiting), and I am currently working on the automation of that layout. It will not be wise to install scenery on this layout until the 00 gauge baseboards that go above it have been installed, and all the signals will have to be removed before that installation.

Here is a recent picture of the shed with the N gauge layout in a more complete state:

The time has come to resume progress towards the 00 gauge layout, and I thought that it would be interesting to document that progress here.

Layout concept

The layout is intended to be set on the Southern Railway in 1936 on the south coast of England in the Hampshire area, on the boundary between the former LSWR and LBSCR systems, after the completion of the Brighton electrification but before any further main line electrifications had been completed, the layout being set in non-electrified territory and at the height of the summer season. The following schematic should explain what I have in mind for its setting.

Reality


The world of the layout


Services will include expresses to Waterloo via Basingstoke, including the non-stop all Pullman "Bournehampton Belle", otherwise comprising an alternating hourly service, one every two hours being non-stop and the intervening services being semi-fasts or portion worked Poole or Weymouth trains that divide/combine at Eastleigh, relief trains for holidaymakers, business expresses to/from London Bridge, with a single Pullman car, a service pattern left over from the LBSC, semi-fasts to London Bridge formed of non-corridor stock, the daily Brighton to Plymouth service, which changes locomotives in Bournehampton, semi-fasts to Brighton, Salisbury, Basingstoke and Weymouth, cross-country services to Cardiff, Swansea, Manchester, Liverpool and various other Northern destinations, and local cross-country services on the Didcot, Newbury & Bournehampton joint line which, for the summer 1936 timetable, is experimentally worked by a GWR Park Royal railcar, local services to Chichester, Fawley, Poole and Eastleigh and parcels trains to London, Brighton and the West Country. This service pattern is fairly closely based on real timetables for Southampton (for the LSWR services) and Portsmouth (for the LBSC services).

Era

As stated above, the layout is intended to be set in 1936. However, it is intended that it should be possible to backdate this by about 20 years to a pre-grouping era if I should ever find that I enjoy building rolling stock kits enough to justify this. The plan is to start with being able to run the layout with bought rolling stock and experiment with kit building later.

The track plan

The track plan has been through many different versions and amendments. This is the latest version:



The upper area represents the scenic section and the lower area the fiddle yards. The tracks are colour coded as follows:

* white: main line, scenic section;
* light red: sidings/yards, scenic section;
* dark red: locomotive sheds, scenic section;
* orange: carriage sidings, scenic section;
* green (various): through lines, fiddle yards;
* yellow (various): carriage roads, fiddle yards;
* blue: light engine stabling, fiddle yards;
* purple: railcar stabling, fiddle yards; and
* bright red: turntable overrun sections, fiddle yards.

The outer pair of tracks represent the former LBSC lines towards Brighton and the inner lines represent the former LSWR lines towards Eastleigh. The grey rectangles represent board joints and the black rectangles the support brackets. The smaller purple rectangles represent electrical section breaks for occupancy detection purposes. It is assumed that all turnouts will have such breaks on all exits.

Fitting the layout into the room

Using SCARM allows me easily to produce a 3d representation of my shed and the various layouts within it. Here are some renders of how the interior of the shed will look with this layout in place. The N gauge layout on the lower level, as well as some further planned smaller portable N gauge layouts on the lower level on the other side, are also depicted here, but as baseboards only, without showing any trackwork.













As should be apparent from the pictures, the layout is intended to fit on wall brackets. The plan is for this layout to house lighting for the layout(s) below, which I hope to have computer controlled for a day/night lighting effect.

Electrics and operations

The layout will be DCC and computer controlled/automated using TrainController. The intention is to run to a full week long looping timetable in real time, with optional automatic random disruption. The intention at this stage is for the layout either to be fully automatic, and simply observed, or, optionally, to be able to be set up in a semi-automatic mode, where the trains are driven automatically and the operator(s) take the role of signallers in one or both of the two signalboxes on the layout, for which I hope to build some lever frames. Another possible operator role might be managing the engine (sub-)sheds, but I have not quite worked out how or whether this will work yet.

Full signalling and automatic station announcements are planned. The fiddle yards, too, will be automated, with trains changing locomotives and locomotives being turned automatically: hence the fiddle yard turntables.

Rolling stock

One of the particular joys about modelling the Southern Railway is the enormous variety of pre-grouping locomotives (and, to a lesser extent, carriages) that lived on well into the grouping era. Had there been a much greater variety of pre-grouping motive power and rolling stock available ready to run, this layout would have been set in the pre-grouping era (hence building in the ability to backdate if I acquire a taste for building kits). In its 1936 guise, of course, the older pre-grouping designs would be mixed with relatively more modern designs.

Some highlights include:

Current state and progress

At present, the baseboards have yet to be constructed, although, as can be seen, I have a good amount of rolling stock. I am in discussions with the people who built the N gauge baseboards, and awaiting a quote (which the company will now only provide quite shortly before the works are due to start owing to inflation and rapidly fluctuating materials prices).

The scenic section will use Peco Bullhead track, and I thus need to await the availability of the Bullhead slips and crossings, which were supposed to have been available by the end of 2018 but which have been delayed enormously, before starting on this, although I believe that there is at least some suggestion that these may be forthcoming this year. I have removed the few medium radius turnouts that I had formerly inserted into the scenic section as I understand that these will not be available for longer.

Since work may be able to recommence on this before long after a period of nearly 3 years of relative stasis, I have been checking to ensure that all the things that need to be done can be done relatively readily, updating research, revising the track plans, acquiring remaining necessary rolling stock and other matters. One recent change has been in relation to the turntables: because I need turntables that will work with TrainController, I have now specified all the turntables as being of the Peco type, as I intend to use ADM turntables in each location, and I do not want to have to rely on being able to build a bespoke custom turntable from a kit in order to get the layout up and running. The Peco turntables are a bit on the large side, especially if I plan possibly to backdate to the pre-grouping era one day, but I need to plan something that I can be confident can be built to a reliable working standard within a reasonable time. I am minded at this stage to ask the baseboard people to liaise with ADM Turntables to ensure that the turntables be built into the baseboards before they are delivered, as I can see it being extremely difficult to retro-fit the turntables, especially that intended for the LBSC lines (top left) to the scenic section with the N gauge layout underneath.

I cannot wait to see how this layout progresses.

I cannot wait to see how this layout progresses.

I shall rather look forward to this myself! It has been a while in the gestation and I am still to receive a quote for the baseboards - but hopefully progress will be made before long! I have already resumed rolling stock purchases in earnest.

Hello and welcome to the forum
I noticed you have completely covered your baseboards with cork.
Where did you get the cork from and what thickness is it? I will be starting a new layout soon and on my last layout the tracks were fixed on to the ply board with out any underlay. The noise of the locos running was not too loud until I glued down the ballast which did increase the noise level very much.
Thank you
Puddles

[jamespetts]

The cork is 1mm thick. It comes in rolls and is self-adhesive. I cannot remember where I bought it now as it was some time ago. On the N gauge layout, I have covered the whole layout in cork and then had another layer of cork under the scenic section track. This is because I use code 40 track in the scenic section, which needs raising with the cork to match the code 55 track in the fiddle yards:

Code 40 (right) vs code 55 (left), the code 40 track packed with an extra 1mm of cork. by James Petts, on Flickr

I did build this layout by using the self-adhesive backing to stick the code 40 track to the cork (in the fiddle yards, I used track pins), and stuck the additional cork to the whole layout cork covering using PVA. However, this was a mistake, as the self-adhesive cork backing did not stick the track well, and I have had to replace this with PVA incrementally.

Having a whole layout cork covering also has other advantages: it means that things such as the bases of signals can be made flush with the surrounding height by cutting out an area of the cork:

It is also good for bedding in buildings.

As to noise, I have not tried this myself, but I am told that using Copydex instead of PVA can reduce the noise caused by gluing down the track. I am not sure whether this is usable for ballast, but I believe that there is a product made by Woodland Scenics that does something broadly equivalent.

What does the outside of the shipping container look like, have you clad it or similar.

[jamespetts]

The only exterior picture that I have readily to hand is this one:

It is not a shipping container so much as a garden room - it is insulated and clad with cement fibre composite board. It was built by a garden room company.

Thank you James for your reply about the cork.
That was a bleak winter day when you took that picture of your shed, seeing all the terraced houses built from yellow stock bricks brought back memories from my childhood when I lived in London at the time when the bricks were more black than yellow. Lots of pollution from steam trains and coal fires in those days
Hope to see more pics of your layout as it progresses.

I have been working on some modifications to the track plans, particularly with relation to the engine sheds. Since returning to working on preparations for this layout, I have been focussing on streamlining the build by removing as far as possible unnecessary obstacles or difficulties. One of the things that I altered with this in mind before posting the track plan in the opening post of this thread was the former smaller turntable, which would have had to have been built from a kit of dubious availability. Since I have not built any turntable kits before, I was concerned about making the layout dependant on my ability to do so. I also discovered that the turntable size that I had in mind in was in any event too short for the locomotives that would be using it. I thus decided to specify all of the turntables on the layout as the standard Peco turntables as supplied by ADM Turntables (a supplier of automated turntables, based on the Peco turntables with their own automation equipment added, that work with TrainController).

This then had the consequence of having two quite large turntables next to each other. I then undertook some research on historic engine shed designs in which two different companies had different engine sheds next to one another. I found that the National Library of Scotland maps, especially the larger scale maps, which are detailed enough to show the actual track layout at all the stations in the coverage area of these larger scale maps, very helpful in this regard. What I found was that, in general at least, there would often be two turntables where different companies' engine sheds were on opposite sides of the tracks (e.g. Sailsbury, Bristol), or at opposite ends of a through station (e.g. Cambridge) but, where two different companies' engine sheds were both on the same side of the tracks, there would usually be only one turntable shared between them (e.g. Weymouth, Bath Green Park). Since the need to represent multiple company sheds is in any event linked only to possible future backdating plans that may or may not transpire, I took the view that it would make more sense to represent the engine sheds, although still separated into two sheds, with a single turntable shared between them:



This has a further advantage: it reduces the density of trackage in the far corner of the layout where access will be difficult owing to the N gauge layout underneath. The turntable area is still quite close to the pair of tracks running in a quasi tunnel section, so I imagine that I shall have to have a representation of retaining wall in the area of the turntable.

This diagram also shows the uncouplers which were not shown on the previous diagram: black for passive uncouplers (i.e. fixed permanent magnets) and red for active uncouplers (servo powered permanent magnets that can be brought up to the baseboards to operate or moved far away when no uncoupling is desired).

The plan at this stage is to have the turntables, if at all possible, pre-installed when I have the baseboards made, as I do not think that it is likely to be practical to install turntables in the corner areas in particular.

Here are some updated 3d renders:

A slight further refinement to the track plan: the reduced engine sheds have allowed me to have the rear lines (the lines to Brighton) moved slightly further away from the wall to give more clearance:
