Wierd but Helpful
I had created a route using my old XP machine but had failed to add a road and track piece, so as to start a new database for both. On a hunch, I copied pair of databases over from another route that I had not done anything with yet and edited the database files to remove everything except the first few lines which just define what is coming but do not indicate the number of nodes, nor what the nodes are. Then I attempted to open the route in TSRE and it worked. So then I went way off track route and placed a 100m track and 100m road piece with TSRE. Looked at the database files with my text editor and noted that now 3 nodes were entered into each. So then I used data viewer and this showed the two pieces correctly. So apparently a new database can be cloned from a old one, preferably a nearly empty one, to start adding to a new route. It is still better to do this in MSTS/RE but once the old XP gasps it's last, I may have to make do with what I have.
