@Apples55: You know I agree with you. Those PRR cars first came with a set called " The Broadway Limited" which included an engine, tender and 3 cars... 2 Pullman and an observation. Then later Lionel offered an add on that included the RPO and maybe the baggage, then even later they offered a "Presidential campaign" car with all sorts of stickers to put on what was really just another observation, finally, and much later by my recollection, they brought out a dinning car. This all stretched over several years so it took quite awhile to get them all. When done, I am not sure the original engine could pull the whole train.
