Theoretically, TransDEM can add UTM tiles to an existing route, but the Trainz version has to be T:ANE SP1 or lower. And the procedure is:
- Use Trainz Content Manager on the existing route and "open for editing".
- In TransDEM, identify the exported route (can be a bit tricky if the original route generated by TransDEM is still in the same folder).
- In TransDEM, export the new UTM tiles to the exported route.
- In Trainz Content Manager, add the newly created UTM tiles.
- In Trainz Content Manager , commit the changes in route that had been opened for editing.
However, if your Trainz version is T:ANE SP2 or higher, this does not work. With SP2, Trainz has changed route file formats and TransDEM cannot yet read the new structures. But reading is required as TransDEM would modify the route and then rewrite it with the anchor points for the new UTM tiles.

- opened the new DEM
- opened the 25k map for ground textures.
- Both the DEM and 25k map for ground textures disappeared.
For a quick recap you might want to do the "Muengsten" tutorial again, from the TransDEM Trainz manual, with all its steps, as it illustrates the export procedure in all detail. And that's the better explanation than any instructions I'd write here.
The data sources in use have little to do with the problem your encounter, so the following remarks are just hints.

With these hi-res LIDAR DEMs you have two variants: DSM and DTM. "Digital Surface Model" and "Digital Terrain Model". The DSM would include buildings and other structures, maybe even forestry, like the good old SRTM satellite data. I would normally go for the DTM. That still includes earthworks, like cuttings and embankments, river/reservoir dams and bridge abutments, but no buildings.
