My Williams PRR steamers are the backbone of the fleet:
- K4s (2) - equipped with TrainAmerica TMCC, EOB, and Railsounds
- L1s - equipped with TrainAmerica TMCC, and Railsounds
- B6sb - equipped with ERR TMCC, and Railsounds
They were very smooth runners conventionally, and perform even more spectacularly under command control. And of course, they pull well.
