It seems that a former ACL 10-6 sleeper (in specific "Duval County", later Amtrak 2782) still exists up in Pocatello, ID. Wasn't aware this car it existed until I stumbled on this eBay listing. Add that one to the list of somewhat out of place rolling stock.

As much as we complained about Amtrak, wouldn't you love to turn back the clock and take a cross-country journey in 1975?
