The question was asked a short while ago on this list, what was a flying
switch? I don't remember seeing a response, so I'll try to give a
description. Please excuse the duplication if there was one already give.
It was a way of getting a car behind the engine into a facing point siding
or track in front of the engine. A full crew was needed to make this move.
One man at the switch, one riding the brake, and one pulling the pin or
cutting lever. Oh, and a good experienced engineer! Level or ever so slightly
down grade was desirable. If the grade was up hill you best NOT try it.
When everyone was in position, and the air brakes have been bleed off on the
car or cars, the engineer would notch out the throttle till the desired
speed was reached for the distance the car or cars had to go. Upon the
conductor, or man riding the cutting levers signal, he would apply the engine
brake, never completely shutting off the throttle. This would momentarily have the
car roll into the engine enough for the slack to be in, so the pin puller
could pull the pin. With that accomplished the engineer would release the
engine brakes and open the throttle full to pull away from the car now rolling on
its own in the same direction the engine was going but at a slower rate of
speed than the engine.
The second the engine passed the points of the facing point switch the man
positioned at the switch would throw it, so the following or free rolling car
would roll into the desired track. When the distance between two moving
pieces of equipment was not great, this became an anxious moment for the
switchman. The man riding the brake now had to make sure he stopped the car before it
went to far, or just in the clear, if the engine was going to come back and
couple up to the opposite end of the car and spot it, or take it some where
else to spot.
I was a quick way of getting a car spotted or on the other end of your
train, but it all took team work, practice and a good knowledge of the gradient at
every location. Oh, and you wanted to make sure you had a good working hand
brake on the car or cars being flyed.
When Railroads started getting more blood out of the stone, by removing the
third member of the ground crew the, the pin puller and man riding the brake
often became one in the same, or the guy at the switch hopped on the brake as
it rolled by. Today with only one man on the ground and no more blood in
the stone, it's a practice that's become HISTORY!
This is differed from a DROP in that by doing a drop you simple cut away
from cars. Bleed them off, ( release the air brakes ) and let them roll into a
desired switch or simple down the main, after the engine has gotten out of
the way. No start with the engine is needed, just the proper gradient.
Centrifugal force does the rest. Again a good hand brake or brakes is needed.
This ( if had to be ) can be all accomplished by today's one man ground
crew, but takes much longer, isn't legal, requires the stone be given a blood
transfusion before and after the move, which never happens, and thus is also
becoming HISTORY.
Hope this helps
