I built the board for the second layout today, it is an end-to-end board which will fit under the window. Construction was similar to Knell Lane, a wood frame but i used hardboard instead of MDF for the top (mostly because i had some available which was the right width). I'm thinking of having a layer of foam board on top of this which will be what the layout will sit on.
Now for the big surprise, i think i might go OO with this new layout. I quite fancy an MPD or engineering yard layout with the back line being behind a screen and being the fiddle yard. I still have some work to do on the board anyway but we might be able to start developing something pretty soon. Here my Class 73 and a NSE coach have been used for size testing. I'm not sure if any of my legacy OO fleet will actually run anymore though i guess we'll just have to see.
