The second 0452 has the body of the original Car F (originally chair car 24). Some forensics performed on the body revealed the car number "24" over one end door and the letter "F" on the side of the carbody. This is the car on the C&TS.
Second Car F, with the emigrant sleeper body, goes on to the fame and fortune, becoming car B-5, later B-2 (and part of the 3-car President's Train), sold by the D&RGW in the 1950's, moved to Oklahoma, bought by 5 guys (Cinco Animas - "5 Souls"), and rebuilt at Burnham removing one of it's vestibules, returning to Durango for charter service.
