When building a route with terrain elevations generated by DEM data, it is rare that there are any truly flat areas. From my understanding of how DEM data is made, the tops of trees, buildings and other objects influence the data so what might look like hills are actually trees, buildings, etc.
So when building a station or railyard, can we assume the terrain should be relatively flat, and thus any bumps and other elevations are not the ground itself but objects on the ground? At least in Trainz, the turnouts are very sensitive to elevation differences between their various parts.
Do you use the terrain panel and flatten the part of the baseboard where the tracks are placed? Do you use the smallest radius to only affect the area directly under the tracks or level the whole general area? Do you use the average or the lowest point as a baseline elevation?
