    Back in the storm of 1952, Rotary Snow Plough 7222 had an air pump failure and its brakes locked up.
    I'm assuming they are talking about the air brakes right? How did they fail exactly?

    BTW, why didn't they drop off the rotary in a siding and reverse the cab forward mallet towards the City of San Francisco?

    >air pump failure

    Most likely caused by a compressor fault, No compressor = no main reservoir.
    Westinghouse brakes require air pressure in the brake line, no air in brake line = brakes on.

    As for what to do in the activity, you can do whatever you want.

    I was talking about in real life why didn't the crew unhook the plow in a siding and then attempt the rescue.

    It is a bit difficult to move a car with locked brakes, without damage to the wheels.

    No what I meant is when they recieved the call for help, then shunt the rotary into a siding, so if it's brakes did get locked up, it wouldn't be in the way. Also, it would be before the issue happened.

    If they get a call for help, it would be to get someone out of a snow drift!

    In both real life and the activity the rotary plow was on the front end of the Cab Forward heading in the opposite direction to the City of San Francisco Express. They had to reverse to get them so the plow would be on the wrong end of the loco. That's why uncouple the plow in a siding, so it's not going to be dead weight.
