Hi Big Jim,
The interchange on the main line isn't going to be there, the tracks will be straight through. I didn't say this above but there will be a full set of interchanges on the other half of the baseboard allowing trains from both directions to change tracks.
The other side of the baseboard there are going to be mainline interchanges, two sidings, carriage wash, and a maintenance building. I don't have enough Kato Unitrack to do all of it.
The trains running on there are just what I had to hand (I know they're going the wrong way). I have a full rake of GBRF coal hoppers somewhere.
I'm not to concerned with the signaling on the main line, I was more interested with getting the signalling inside and leaving the yard correct. With the limited space (180x80) I have not everything is going to be prototypical.
Thanks, Tom.
