Thanks guys - re the screenshots, most of it is due to the excellent sim lighting effects, angle of shot, superb assets etc etc all adding up to give a decent shot.
Class1987, I have no idea about creating assets, all I can do is reskin. New Street is just made up of various bits and pieces at the moment.
I've been pottering away at reskinning more stuff such as roads, lanes etc - trying to get more variety into the route. Here's a shot of the Saltley area again, with a new reskinned track access lane inserted(no idea what the technical name for it is!). Here you can also see a representation of the Washwood Heath Siding No 1 shunting frame (not completely sure if it's still present?).
Regarding variety, can't wait to get hold of the new Thompson/KRoss route, mainly for the route itself, but also for what looks to be an excellent range of new tree/vegetation assets. I'm sure this route will set a new benchmark.
