Assisted a railroader on his decoder install on a PRR 0-6-0 switcher imported by Sunset models back in the 70's.
Drilled out some speaker holes.
With a slope back tender no room for the decoder so we 'dremeled' out the bottom where the coal is so the decoder can be under the coal load. The front of the tender, already, has a hole for coal shoveling so the wires can route out there.
A very high quality gear and motor: I was impressed.
Of course we did some 'train running' after.
He ran the Burlington 1934 Zephyr.
I ran the Milwaukee early Hiawatha.
