Lage DEM routes
I am giving my own personal advice, as my prototypical route from Huntingdon to Johnstown Pa, is rediculously large, and will take me seemingly forever to duplicate the @ 300 miles of combined trackage.
So DEM's make all the terrain for you...but your route will be huge, like mine is.
Maybe you could replicate only the important stations, yards, and rail fan sites...and condence the 10,000 baseboard route into a more fun condenced 100 baseboard route.:wave:
If I had to do my route all over again...I would do Phila Greenwich Yard, Zoo Interlocking, Paoli Yard, Lancaster (Strasburg RR), Harrisburg-Enola Yard, Lewistown, Tyrone, Altoona, Horseshoe-Muleshoe Curve(s), MG Tower, Cresson, Cassandra, Johnstown, Bolvair, CP Conpit, Pitcairn Yard, Pittsburgh. And all in condenced and merged @ 200 baseboards.
My route is presently 10,000 baseboards and is 567Mb.

The DLS limit is only a maximum of 30-60Kb. So as mine is huge, it will have to be hosted on a third party site.
I have started a fourth route, in addition to my
Enola Yard,
Pictairn Yard,
Horseshoe Curve route(s)...the
British Columbia-Kicking Horse Pass-Spiral Loop Tunnels, which is on @ 7 baseboards at present, and may be extended East to Lake Louise BC, and West to Field BC, all in @ 50 baseboards.
