Remotoring Westside PRR G5 4-6-0 Ten Wheeler
Original Westside Model

Prototype
90 G5s locomotives were built for the PRR between 1923 and 1925 at the railroad's Juniata Shops in Altoona, Pennsylvania. Thirty-one more were built between 1924 and 1929 for the Long Island Rail Road, then a PRR subsidiary. https://en.wikipedia.org/wiki/Pennsylvania_Railroad_class_G5

Same boiler as H8 and E6.

Coreless DC Motor

Coreless DC Motor

I replaced the open frame motor with a coreless DC motor Maxon A-max 16 12V/2W. The motor starts at about 2 V and draws 130 mA.
