New Layout Description:

Celbridge started April 2016 is no more, I’ve lifted the track and started afresh.

My shed is 3.4 m x 2.2 m and the layout is to run around the circumference. Depth of layout is 500mm all the way round. I have it set at a height of around 760mm so that I can sit comfortably in the chair and work away at it.

Unlike Celbridge this layout is going to be end to end. Experimenting with track plans at the moment.

I have added an extension to baseboard for return loop (non scenic) at one end and terminus station at the other end.

Here is track plan.

Interesting layout style! Irish or anything else?

I like the name!

I do no whattocallit. “Kingsbridge”.

I wanted a terminus station like Heuston, with the return loop hidden by a scenic break, probably road overbridge. I run trains to Cork and then they return.

What we think will fit in our heads and what actually fits are two different storys.

Now I have a fairly big room for my layout, however the first plan doesn’t work, not enough room for platforms with a least 3 carriages.

I have revised it as shown. Because the return loop is done with diamond crossing there was no issue with electrical short circuit. However, the introduction of the Y junction creates a continous loop.

I like the symmetry of the Y junction and it allows for two decent sized platforms, with 3 lines.

Currently, and I’m still just playing around, the single power controller is located at the green track in the middle line.

To prevent short circuits, I have used isolated tracks shown in red as per Hornby Track Plans 8^th Ed (£4.99) P. 30.

Lots of switching on/off isolated sections depending on which arm of Y junction is chosen.

I’d say that will work a whole lot better. Presumably multiple unit operation primarily, or push-pull?

Not push-pull if my understanding is correct. Anytime i push carriages or wagons they always seem to get snarled up and uncouple or derail.

Locos will enter platforms at station "head" first. Then uncouple carriages.

Another loco will come from storage sidings (Inchicore) and couple to carriages in station and off it goes again. Lone loco will then goto Inchicore.

Work in Progress

Sorry to see Celbridge bulldozed for redevelopment, but Kingsbridge looks like it's going to be a worthy succesor.

[Paddy Mac Namara]

I'm not straying far from home with my layouts, hey stick with what you know. I've been using the Dub-Cork route since a child.

So that Y junction causing way too many comlplications with shorts and just way too many isolated sections to keep track off. So this is next track plan.

This gives me 4 platforms at station. However when i did a few test runs with locos and carriages, i realised that at best i'll only get about three carriages to fit.

So ive gone with 3 platforms in this new iteration.

Interesting. I like the loop with the crossover which feeds trains back from whence they came, but on the correct line.

However, how does an arriving train (an "UP" train), get across to the departure platform to form a "Down" train - don't you need a crossover somewhere? You've hit the age-old issue that points take up a lot of linear layout, which I sort of got round by buying a big house and mortgaging myself to the hilt (paid off when I was 75!).

Good luck though, just a bit more innovation?

[Paddy Mac Namara]

Thanks, very useful. I'll have to investigate some options. 

[Paddy Mac Namara]

I have included a cross-over from up to down as suggested (thanks).

The return loop has isolation gaps on both rails, shown in red.

Power is fed to down from red curved track. I can isolate the up part of the return shown yellow. Switch the points at the cross-over and bring loco onto downline without any shorts via the green tracks.
