Mason Bogie versus the Forney

Okay all you commuter engine affidacios....


Please enlighten this superpower behemoth affidacio...

What is the difference between a Mason Bogie and a forney?

The Forney has a fixed (rigid) frame, while the Mason has a swiveling engine frame (bogie) under the boiler. The Mason's boiler, cab and rear frame are a rigid assembly.

The forney's engine is part of the frame, like a normal engine, but the truck under the tender is like a freight truck, right?

On the mason, BOTH units are "trucks" like on a passenger car or diesel, right?

Just making sure I understand.

Thanks for the info.

Correct. The Mason's engine isn't a plain truck though. It has a slide plate arangement under the smoke box to carry some of the weight and the larger Masons had a pony truck under the front of the engine bogie as well.

okie.. thanks much for the info!
