Here's a few things to check.
1. Is the Lat. Lon. for your route set properly.
2. Did you download DEM data for the KC area?
3. Is the data in the right format? - ie 1 arcsecond or 3 arcsecond SRTM topo in .HGT format
4. Are the filenames in the right format - ie N24W116.hgt
5. Did you put the data in the right folder? eg Railworks\DEM\SRTM
6. When you import the dem, be sure you are not selecting too large a region ie 1x1, 2x2, etc - drop down to 1x1 to be sure
