Ok here's one that probably hasn't been done before...
This is a BLR shops frankenstiened SWEEP that serves as a plow unit.
Plow blade is made from an old 35mm film canister. Unit is operational and is made up of various detail parts and scrap loco parts. Windows are mirrored on the outside to cut back on glare in the winter snow. The unit was inspired by Bob Boudreau's CN SWEEP back in the 80's.
