Hi, it's easier to use the content manager from the start-up screen, the is a much better filter system.
The problem with Highland Industries (IIRC) is that there's so many of them!
I'm assuming that your downloading from DLS.
If you have the route as a CDP, use content manager and the import options.
You don't appear to have other Trainz versions with this username, but if the route is from pre Tane, you'll need to load it into an older version, export as CDP, reimport to TANE, repeat to TS19Colin
