Conrail(CSX) uses Beilhack (now AEbi Smidt Germany snow blowers.
the frame is a turntable so unit is bi-directional
Now that is neat!!!!
Now that is a unit that really means business in a real world way. Never have seen a blower, of any kind designed with the rotary "cutters" as this is. Looks like that design would really be efficiient. Cutters to cut in to the snow "wall".....horizonal rotating blades to further grind it up and get it towards the wheel that blows it up and out the stack which ever way it's pointed.
Am I understanding correctly that whole platform it's mounted on is rotatable to allow it to reverse directions in such a manner....if so, that's wild.
