Wikipedia L1s

: Class L1s on the Pennsylvania Railroad comprised 574 2-8-2 "Mikado" type steam locomotives constructed between 1914 and 1919 by the railroad's own Juniata Shops (344 examples) as well as the Baldwin Locomotive Works (205) and the Lima Locomotive Works (25). It was the largest class of 2-8-2 locomotives anywhere, although other railroads had more Mikados in total.

Preserved #520 at the Railroad Museum of Pennsylvania.

Coreless DC Motor

I replaced the open frame motor with a coreless DC motor Maxon A-max 22 12V/6W.

Coreless DC motor (Maxon A-max22 12V/6W). Motor starts at about 1 V and draws 110 mA on the test stand.

Shafts and U-Joints from NWSL

You can get it from Old Pullman or direct from NorthWest Short Line.
