The mechanism behind route naming is simple. We normally use a common folder for exchanging data between TransDEM and Content Manager.
We start in TransDEM and let TransDEM create the route initially. This generates a folder with the new route files in it. The folder has the name we assign in TransDEM, e.g. "My Route".
Then we use Content Manager to import the route from the common folder to the Trainz internal database. After import, the original route is still present in the common folder. It will not be used by Trainz, though, because Content Manager has made a copy. Any editing in Surveyor will affect the internal copy, not the original, TransDEM created route.
At a later stage we may want TransDEM to add more data to the existing route. The route has already been edited in Surveyor, so it is no longer a clone of the one in the common folder. Content Manager offers functionality to temporarily export a route for external editing. Content Manager searches the common folder for a route with the same name "My Route" before placing a new copy of the route into it. If it finds the name, it still exports the route, but under a new cryptic name, without any user confirmation. Therefore,
before opening any route for editing in Content Manager, always
remove an existing copy of the route from the common folder, by moving, renaming or deleting the original one.

The only file that was changed was the mapfile.trk
Is this correct?
Yes. The .trk file is the one that holds the spline objects. It stores the control points, the links between them and the spline KUIDs.

I found something in my route. Only a small part was changed.
Before adding new vectors to an existing route, TransDEM first reads the vectors from the .trk file. If the new vectors have the same coordinates as existing ones, they shall be ignored (at least that's the intended behaviour).
So, if you already have railway track at the very same location where there should be a road, TransDEM discovers the track and will not add the road.
