Along with all the other data I got from OS is a set of files in .dxf format. They produce a wonderful array of blue lines all over the shop. When I came to export this to Trainz I found that the 3d options were now available - unfortunately I have no idea how to set them at the moment so left them at the default settings.
Cartographic map data is usually 2D. In cartography, height (or elevation in American English) is seen as a mere attribute, not as the third component of every point. Try to get hold of CAD track infrastructure data from Network Rail. That should have it all.

That did show me how Transdem has smoothed out the hills and why it was so unrecognizable in areas Im familiar with with the ground territory.
While TransDEM does apply some smoothing (which can control when exporting to Trainz) the main reason for the terrain to appear less accentuated in Trainz than in nature is the DEM itself and its limited resolution. This has also been pointed out by Vern in the Auran forum. Have a look at these
examples of USGS DEM data.
