Description Mount Rainier Scenic RR's Polson 70 is prepared for the first run of the day.
This 1922 Baldwin came out of a frame-up restoration in 2011 in better shape than the day she left the factory. MRSR crews comment that even at only 70 tons, she is a strong puller. But it's raining today and traction will be at a premium.
Note that the train is coupled to the front of the locomotive. While that may not be normal for most steam locomotives, this unit was built as a logging loco. As such, this loco can push or pull a train equally well in either direction. A very desirable setup if your short line does not include some means of turning the loco around at the end of a run.
Also, see for more info on this unit.

I like how small her drivers are

Yup. Big fat boiler and drivers under 50" = max power at speeds of under 30MPH.

I wouldn't call her boiler fat, I'd call it big. The Erie's Triplexes are a different story, but even their boilers weren't big enough!

For a 70 ton loco, that is a fairly big boiler. #15 on my front page is only 90 tons and is built to very similar patterns. (Albeit with piston valves and proper superheaters)
Many British locos of similar size wouldn't have nearly the tonnage or boiler diameter. They would have much larger drivers though. At the same tonnage, they would be in a totally different class.

This loco made the cover of Trains for the May 2012 issue.
