Some time was spent on getting the platforms at Evercreech Junction just right. After a couple of false starts I finally produced this version in balsa wood (easy to shape) toped with a layer of cereal box card (easy to shape after the balsa has been shaped, and easy to paint and stain. The ramps, though, needed to be propped up with more card, like this:

Layout work

Then the platforms were painted lightly in several coats and three different greys until I found a shade I was almost happy with.

Layout work

Elsewhere, more scenery formers were added between the colliery and the main line out of Evercreech.

Layout work

Then one of the curved storage lines in the colliery area was taken up and relaid as a straight line. Having found a good modeller's article on the colliery I now have a much better idea of how this area should look.

Layout work

Here's an overview of the entire Evercreech Junction (EJ) area at the front of the layout, with painted platforms in place faced in brick and stone paper, and both water columns in place (although the farther one would soon be taken up temporarily (aka accidentally knocked out of its housing).

Layout work

The loading gauge for EJ Goods has been permanently fixed in place.

Layout work

Underneath, some more of the route setting relays have been put in place.

Layout work

Needless to say, I didn't wire these in. They're an unexplained mystery to me!

Layout work

Here are the beginnings of an experiment to produce an uncoupling ramp. The brass square rod which fits inside another rod was easy enough, as was soldering the brass ramp to the top of the thinner rod. The servo underneath the board which operates it will take much longer.

Layout work

Much easier to complete were three more of the kit-built rolling stock cartridges which will sit under the fiddle yard.

Layout work

At EJ station I decided to add a bit of a raised roadway at the back so that it comes up to meet the back of the stationmaster's house. Visible at the bottom of the photo is a white metal post for the level crossing, but more of that another time.

Layout work

And now for a bit of major work on the incline.

The top section from the bridge up to the joint with the MPD board has never worked properly. I decided it was time to rip up the entire thing and start again. But first I needed to store some rolling stock prior to removing the fiddle yard. That meant a few extra storage trays, and at last I have enough stock of the same type in one tray to be able to label a few of them.

Layout work

With the stock removed, I was able to remove the controller section from the front of the layout, and then detach the fiddle yard and heave that out into the spare bedroom (it's really a two man job, so heaving it out solo requires a bit of effort). Then the layout could be wheeled forwards so that I could get around the back (after refitting the controller section so that I could send test trains up the incline).

Here's the old incline, with the very bad track connections at the bottom and the Grand Canyon jump across to the MPD board at the top. I've already started removing support blocks and thinning them by at least half of their original width to maximise the amount of track underneath that can be reached.

Layout work

The old board joint at the top of the incline was on a curve in the track - never ideal - and it caused some stock to derail. Now I cut a chunk out of the MPD board to attach to the incline and change the place at which the two met.

Layout work

The MPD board off-cut was clued and screwed to the incline and an extra support put in place underneath. That also meant sawing off part of the metal support bracket under the MPD board.

Layout work

With the board joint now in place and level across the very much smaller gap, I could concentrate on laying the inside track (which would have the tighter radius). Constant testing produced a curve which was free of any wheel lock-up, and placing the track joint beyond the right-hand side of the bridge (under the hammer handle in this photo) meant no awkward rail joiners just where the curve tightens up.

Layout work

While we're waiting for the glue to dry, here's a shot of the main baseboard, pulled out into the middle of the room and with the controller section loosely reattached.

Layout work

At the top of the incline I took out the cork and replaced it with hardboard of the same thickness. This is where the board joint will go.

Layout work

Extra droppers were soldered under the track so that both ends of the incline have a power feed, and rail joiners on a tight curve aren't the only way of ensuring that power reaches the top of the incline. The track would also be soldered to the blocks which were salvaged from the old incline top (I had to - it's all I have of the stuff).

Layout work

After much track bending and testing with powered locos, I had a top-most part of the inner track that I was happy with, so this could be glued in place. It would have been next to impossible to take it up and use Copydex and still keep the perfect positioning, so I left it pinned in place and dripped in wood glue mixed with water.

Layout work

Twenty-four hours later I had an inner track incline that even a King Arthur could negotiate with ease. This test train also managed to achieve a new record for the furthest a powered train has managed to get on the upper level.

Layout work

Next it was time for the outer track to be tested and laid. This one was a little easier (not necessarily saying much!) as the curve was a little more generous. There's also a little banking going in under the track with the light grey card to offset the slight outwards tilt of the track without it.

Layout work

The next day the top section of track was laid (more testing, more track bending, more success). I did all the soldering across the board joint at the same time, much more neatly and unobtrusively this time than I did before.

Layout work

Here's a close-up of the board joint while the glue was still drying. The red wire is another extra feed wire which would be connected to the main circuit once the layout was back in position. The next job will be to saw across the tracks in the middle of the board joint to separate them. I've already done the inner one here and it's still pretty perfect.

Layout work

Cuts done, the track still lines up perfectly and smooth running has been achieved along the entire upper section of the incline. That lot took a week and-a-half of various sessions to complete. I also started adding some scenery formers in celebration.

Layout work

1 April 2018

Nothing new has happened with the layout this year, but that doesn't mean I can't catch up with the last of 2017's progress.

After finishing off the incline rebuilding work (see above), I managed to produce a test print of the stationmaster's house for Evercreech Junction (EJ). There are no details on it at this stage. It's just a shell so that I can gauge the size. The footbridge is accurate so I can gauge it against that... and the building is a little too tall. Back to the design to trim off a couple of millimetres and also to reshape the rear of the building.

Layout work

On the scenery side of things, some progress was made with two layers of card strips across the vertical formers. This hill would be ready for some landscaping work to go over the top if I only knew how the hill was supposed to meet the upper level. I can't do that until the track is laid up there and I know where the station buildings are going to go.

Layout work

To add to the initial test run at building a rolling stock cartridge, I've added three more of them, all MDF kits from Mill Lane Sidings. You can see that they're labelled up now, two for the Southern Railway's 'Bournemouth Ltd' service using Maunsell coaches, and two for the Bournemouth Belle, using Pullmans. They make it much easier to roll-on/roll-off stock onto the fiddle yard - essential when the layout actually becomes operational... one day.

Layout work

When the top of the incline was fixed up, I laid down card sleeper 'tops' across the track over the board joint. Now I've done the same on the Highbridge loop at the front of the layout. It looks a little rough at this stage but I'm hoping that when a thin layer of ballast goes down in between the sleepers, it'll look much better.

Layout work

More scenic work could take place elsewhere, this time on the rebuilt incline. The back 'corner' - actually a curve on the outside of the rail curve - got some of its card formers and the backing for a sleeper-built retaining wall. This corner will be filled with pine trees and purple heather, both well known for living in the Bournemouth area.

Layout work

I don't think I've included a proper shot of the EJ footbridge yet. So here it is. The single matchstick glued into the corner was actually part of the real bridge (a wooden beam, not a matchstick). In fact there was one at each corner, added by the Southern Railway to secure the steps to the replacement overhead section when that replaced the original wooden version in the 1920s. The one matchstick here will be the same colour as the footbridge when it's painted, but the other three will be bare wood, so I can't add them until painting is complete.

Layout work

Another job done was to add an extra stop to the 'Controller for sidings' switch. Settings 1, 2, and 3 are to determine which controller supplies power to the sidings in two locations on the lower level, but it's a good idea to add a neutral setting too just in case no power at all is required. In effect, the neutral setting acts as an extra isolator switch.

Layout work

It's time to test version two of the stationmaster's house, this time with sample windows and doors. It's a little shorter, but I need to do a little more work on the rear so that it sits properly on the pathway behind the platform.

Layout work

Final job of the year, to drill all the wiring holes for the scissors crossover on the upper level. I'd love to get the upper level working without having to worry about any wiring for something as complicated as this thing, but nothing's going to get through this without relays and points motors being installed. Maybe next year...

Layout work

24 December 2018

There has been quite a bit of work taking place on the layout recently. Mostly it's been scenic-related but there has been some track laying too. And even some wiring (shock, horror). A fresh set of Evercreech Junction (EJ) station buildings was printed off and assembled to check heights and widths against the pretty narrow platform. The waiting room nearest the camera still needs to be shortened so I may have to remove a window.

Layout work

A lot of scenicing has taken place, usually at the rate of half an hour or so at the end of the day. The gently sloping hill down to EJ's goods sidings has been set up with card strips, blending in around the cattle dock, just like the real thing.

Layout work

The slope down from the incline where it sits behind the (eventual) site of the goods shed is a lot less gentle, thanks to the fact that there's not really that much space there.

Layout work

Further down the line, much of the landscaping framework has also been set up. The only bits I can't finish are the ends where they will mask the upper level joints. The upper level's track and platforms will have to be set up before I know what needs to be hidden.

Layout work

Also complete is the outer side of the upper incline. There will be vertical sleepers in place in front of the flat piece of card (extremely tall ones, by N gauge standards!). This is where the pine trees will be placed that always heralded the arrival of S&D services to the Bournemouth area.

Layout work

I gave up trying to find a proprietary tunnel mouth for the exit of EJ under the incline. Instead I cut out a piece of plasticard to do the job. In time it'll be covered in stone paper.

Layout work

Underneath the layout some more tidying-up was done on the new wiring, with this shot showing the double relays for the EJ goods siding area.

Layout work

Something which took many visits to fully set up by my semi-tame electrical genius was the multi-relay which controls much of the route-setting work.

Layout work

Back to the scenicing, the outer side of the main line between tunnel and fiddle yard was given its slopes.

Layout work

Then came a more complicated hillside build - the triangle between main line, incline, and Highbridge loop (lower right).

Layout work

All the card strips were added onto the basic structure to give you a good idea of what it'll look like when it's finished. The thin strip of brown card will be a retaining wall.

Layout work

Then I turned my attention to the small section of track between the fiddle yard itself and the join with the main baseboard. The scenery here not only has to disguise the raised track (or lowered baseboard, if you prefer) but also the large and awkward hole. The backing panel has already gone in and the first of the formers have been added.

Layout work

In the meantime, the first permanent track had been laid across from the MPD upper level board to the Bournemouth West station board. The very first self-propelled service to make the jump across boards was hauled by the Stanier 8F. If that can make its way along a piece of track with that long wheelbase then just about anything can.

Layout work

Back to the fiddle yard board, and the hillside-building at the back has been completed. The basic structure at the front has also been started - possibly one of the most complex areas on the whole layout.

The stray wires and SPDT switch are something else. The fiddle yard itself had a bit of an electrical polarity problem because I'd hard-wired permanent power for the outer track so that I only depended upon the inner tracks to provide power across the cartridges. This was fine when running a train in one direction (into the fiddle yard) but caused a short-circuit when running a train out on the other controller.

Layout work

Paul came up with the suggestion of adding contacts under the cartridges - a very sound technical solution, but one which would have meant a fair bit of rebuilding work to all of those cartridges that I'd already built. Instead I went very simple (which is just about my level when it comes to electrickery). The new switch on the fiddle yard panel (top right) with the direction arrows is my contribution to the problem.

For incoming trains you flick the switch down, for the arrow pointing left. For outgoing trains you flick the switch up. The permanent power to the fiddle yard rails is switched to match the controller being used and there are no more short-circuit problems... I know. It actually worked!

Layout work

Back to the scenery - something that I haven't got around to detailing yet in the Infrastructure thread yet is the building of this terrace of railwayman's cottages. It's turned out pretty well for my very first card building in almost four decades. I needed to get it finished so that I could cut out a permanent base for it and then start securing the rest of the road around this area. Here it is in place.

Layout work

And here it is still in place on its removable base (which I can take downstairs for some more comfortable modelling work on the back gardens and front path). It slots quite easily into its 'hole', while the rest of the wood around the site has been permanently glued down. The next thing to happen along here will be the addition of card formers for more hills. They will mask the joins between baseboard and removable upper levels.

Layout work

That's all still to come though. For now I'd like to wish you all a very Merry Christmas!
