The SFSR had a coach plus this flatcar equipped with railings for a wonderful view. It was cold enough to need our coats, but I once again forgot that the sun can still hurt you even if it's cold, and without sunscreen, I got a bad sunburn.
The train took us down to Lamy, where there was a catered lunch that we ate while the crew switched out cars for exchange to the then-still-ATSF and collected an insulated car of beer for the Coors distributorship. On the way back to Santa Fe, the crew switched the beer car into the distributorship using a "flying switch," a move that I'm really surprised they did, particularly with passengers aboard. It's not actually prohibited by Federal Railroad Administration rules, but most railroads no longer permit it because it can go disastrously wrong. OTOH, I'm glad I got to witness it.
The SFSR ceased operations in 2014, but it has come back to life as a partnership including George R.R. Martin has purchased it and is working with a group of others to get it running again.
