I was in the 2900 car a couple of weeks ago and that car was next to the Sleeper Lounge/CCC (it whatever).Sleeper 2901 is the farthest from the engines and adjacent to the dining car now used as a sleeper passenger lounge - not 2902 which would actually be closest to the engine next to the transition dorm sleeper and farther from the dining sleeper lounge. You have to walk through 2901 to get to the dining lounge if you are in 2902. This is if the sleepers are in the front of the consist. Sometimes they are at the end of the consist and 2902 would be the last car in the consist. Ahead of it would be the 2901 car and then the dining lounge.
