The NEC is the crown jewel of the Amtrak routes that has more trains, serves more passengers and enjoys higher revenues than on other routes. We ride it once or twice per year and every time that we are on it the train is crowded. Since it is heavily used the wear is very obvious and I just wonder how often the cars get to be refreshed/refurbished.
That's not an easy question to answer, mainly because Amtrak has 3 different overhaul levels for these cars. A level one overhaul I believe is mainly just a heavy duty cleaning, fixing broken seats & tray tables, and replacing worn out cushions and other such things like that. A level two overhaul is more severe, where all cushions are replaced without regard to whether it's needed, carpets are replaced, and stuff like that I believe. A level three overhaul sees AC work and other major stuff like that, in addition to all of the above. Please don't quote me on the above, I'm not 100% sure just what happens at each level, what I've provided is just something to give you an idea of the scale of work being done and is my best guess.
Last year Amtrak scheduled 66 AMF-I coach level 1 overhauls and completed 69.
Last year Amtrak scheduled 8 AMF-I coach level 2 overhauls and completed 8.
Last year Amtrak scheduled 24 AMF-I coach level 3 overhauls and completed 28.
Last year Amtrak scheduled 20 AMF-I cafe/club car level 1 overhauls and completed 20.
There are 429 active AMF-I cars of which 40 are BC cars, 45 are Club/Dinettes, and 40 are full dinettes.
