Thanks for passing on your comments. I agree with you, it does need a bit more length particularly for the right hand (station) siding. I am probably only going to be using a single carriage along with a locomotive, hence I don't need to lengthen it much (the locomotive normally went in first, so I do need to). The other siding was for a coal wagon, which would be pushed in (all the way from Fallgate I think), so the length would work.
I am working on a modified design, where the 'quarry' is compressed a bit more to the north, the triangle is moved a bit to the left, a curve is added between the point at the end of the triangle, and the station siding is lengthened a bit and goes more into the top corner. Alternatively, I could use a 4x4ft baseboard
Also, I was planning to put a fiddle yard in the bottom right, probably using a large enough turntable to turn a train round.
Currently, I'm dithering, as I want to swop the polarity of the points' frogs, on whether to use point motors and, if so, which ones to use. Again, any advice would be welcome.
