Robert,
I needed to do some testing this morning, coincidently. As a result, your TransDEM data has been uploaded.
Part 1: DEM, vector route and 1:500k topo maps
http://rapidshare.com/files/43005012/wv1.zip
Part 2: 1:24k topo maps, 1st half
http://rapidshare.com/files/43001552/wv2.zip
Part 3: 1:24k topo maps, 2nd half
http://rapidshare.com/files/43007809/wv3.zip
The parts are about 50MB each.
DEM is USGS 1 arc sec NED, re-sampled to 20m.
Topo maps have have been downloaded along the route path from MS Terra Server USA, via WMS. the route path itself is handcrafted, tracing the line on the topo map. (Looking at some of the tight radii, is this really standard gauge?)
To get started in TransDEM
Open DEM: NED_49863731_t.dem
Open georef. raster map: wmsMap500-001.lgb
Open georef. raster map: wmsMap24-001.lgb
Open vector route: route.str
If anything is missing, you can easily add topo map clippings with the TransDEM WMS client.
This is a fairly long route. To create your Trainz terrain, I highly recommend to split the route into sections (20 miles or 30 km) and merge in Surveyor later. Follow tutorial 1 in the TransDEM Trainz manual to create your Trainz map.
