My thoughts are this:
if Scott offered a 6pk El Capitan & a 4pk Super Chief then we have a very nice 10 car base set. It also give those who just want the El Capitan the opportunity to just have that set & add extra coaches & head end cars.
El Capitan could be 1 transition dorm car, (2) step down coaches, 1 coach, 1 lounge, 1 diner
Super Chief could be 1 4-4-2 sleeper, 1 10-6 sleeper, diner, dome lounge.
extras: baggage, RPO, 10-6 sleeper, High level coach, brass big dome, and all cars with the exception of the RPO could also be done in Amtrak phase I.
these are just my thoughts. I emailed Scott as well. I don’t have any special connections or influence with Sunset/ 3rd rail- GGD. I’m just dreaming. Happy new year everyone.
