Thanks Wim GPR. I've checked the directory and Object is indeed in the railway folder....at the moment there are 4 folders within Object...two routes and two signal.
I've noticed that when BVE is run in a window, right at the top of the window you can see a few lines of scenery - then the large limp of colour starts. There are also blobs of colour around the cab controls that have animation....it's all rather odd!
