I'm going to use this on my Big Boy tour train. I plan on building parts of this year's Big Boy tour routes. I found some DEM's of Cheyenne, WY to Nebraska and toward Laramie and Rawlins, WY and Cheyenne to Denver, and Sacramento to Reno and Sparks, NV, as well as a longer route to Oakland, CA, and a DEM from Salt Lake-Ogden, UT area to Green River, WY. Some of the routes Big Boy is traveling on this year, both UP and NS are freight only with no Amtrak or other passenger service like the lines in Wyoming toward Ogden, UT and into Nebraska, and the former Erie Southern Tier between Buffalo and Binghamton, and other NS lines in eastern PA east and north of Harrisburg, and others. So far there are no public excursions planned, just a few cab rides will be auctioned off for the western leg. I'm going to see it during its eastern leg as I live in eastern PA close to an NS line but not sure if it will be going right through my area. We might have to drive 30-80 miles away to see it and during a display stop. I have the Trainz Big Boy from Trainz Forge.
