Maybe you explained all this somewhere in this thread, one of the other 4 or 5 forums you're running in, or your website, but I'm blurry on the transcontinental routing and the choice of scenes. The layout starts in Altoona, runs through Newark (N.J.?), hits a tunnel past the N&W interchange and comes out in Denver(using a helix going upward, which makes sense since Denver's a mile high) ... then crosses over to San Francisco (Sacramento? Hard to read the tiny print in those huge plan images), and then down to LA? And a Penn Station that was in LA? So I was wondering if you had a business history for this RR to go along with the transcon route. Did it buy out the Q(or Rock Island) to get to Denver, then control the WP/DRGW to get to California? Or build new lines through all these areas? No criticism of any explanation of how this Pennsy got to LA, I'm just curious if the story weaves in real railroads for buyout, merger, trackage/pool rights, etc. As for choice of scenes, having both coasts modeled for a transcon certainly works, but having a little bit of Midwestern prairie would have been interesting. If for nothing else than to find out if "this" PRR picked Chicago or St. Louis as starting point to push on westward.
