Re: Do Not Hump Signs

Larry Jackman <Ljack70117@...>

There were cars especially LCL cars that had what we called a "clock" in them. Couplings were to be made at 4 MPH or slower. The "clock" recorded the impact. They would break at 8 MPH. Beside the recording the impact the kept time and recorder that also. So when the car reached the destination they would remove the recording and then tell where the mishandling happened. That is why dispatcher sheets were saved. You never knew when a car had "clock" in it.

moved. They raised the four
of us that found them.

I am sure there were plenty of claims settled because crews didn't read the placards or the special instructions.

But in a well designed hump yard with computer controlled retarders, there was a greater chance of a claim from flat switching. In older yards with manual retarder control there was a much greater chance of a high speed impact.
