A few trains on the UP-W occaisionally have at least one Pullman. In January I was in 7741 heading to Geneva. It was the only Pullman in the train. Earlier that day there was a train that had two, one was RTA and the other Metra. Since then I have seen other trains with Pullmans in both schemes. I had no idea there was still a cab car running.
