I think what we need to know is
EXACTLY what it would cost to make this route viable again. By "viable" I mean CTC, PTC and longer sidings. The grades on Raton and Glorieta passes would still remain unaddressed but I don't feel like they would be that much of an issue for lighter, faster intermodal trains. This could, in turn, get BNSF interested and they might just decide to keep the route after all. Such an outcome is not unprecedented.
I hate to say it, but Anderson's position that spending several hundred million dollars to really get the line up to snuff for a single daily, money-losing passenger train does not really make all that much sense. What the line needs more than anything else is more traffic. It
CAN be done. What I would envision would be several daily and very hot but rather short Chicago-Los Angeles intermodal trains and maybe one hot Denver-El Paso intermodal train.
If Amtrak and the states involved would be willing to make a bigger commitment then perhaps BNSF would also step up to the plate and throw some of their own money at it.
