I have a nice new route where the track dramatically crosses a valley via a viaduct. I designed it so that the track curves into the crossing, allowing it to be seen for some way ahead on the approach. However, when approached in driver mode, the track appears in the distance, along with the landscape, but the viaduct doesn't appear until the train is almost on top of it, thus totally ruining the desired effect. Despite maxing out the draw distances and trying several bridges, I can't stop it happening. Does anyone know how to stop this? (Trainz 2006 btw).
