1. slotted coupler knuckle, which enabled coupling to the link on a car with link & pin couplers.
2. Coupler painted red. If inspected by the ICC/FRA, this would be a violation. I have read that the reason European & Asian steam locomotives often painted wheels and frames red was to facilitate finding cracks during inspections.
3. No train line air hose. Cars were moved without air although locomotive has air tanks under the running board.
4. Cut lever crushed on one side against buffer plate,
5. Both air whistle next to bell and a roof mounted air (truck?) horn.
6. No letter "F" visible to designate the front of the locomotive.
7. There appears to be the top of an air brake stand visible on the left side of the cab, assuming the engine compartment is the front of the locomotive. Suggests the unit had dual controls or was set up for "left hand" drive.
8. Cab end of locomotive has a substantial snow plow mounted with provision to raise and lower it so that its skid pads ride the rail.
9. Only skinny engineers could run the locomotive based on the narrow spacing of the cab end handrail and the cab wall.
10. Brackets beneath the running board hold a "rooster", a long bar which made it possible to couple to a car with an overhanging load within the plant.
The seller lists over 1,000 slides, both originals and duplicates. I searched both MI and Michigan. The latter turned up a 1978 slide of MIGN's $75 relettering of ex-SOU 2037, leading an ex-SCL Baldwin RS-12 in fresh green and white through Big Rapids. MI uncovered several industrial locomotives in Michigan.
