Here's one I don't recall being addressed anywhere...What locos had/have(?) this device ? I always picture it on the floor of engineer side of E8 or F7/ AlCO FA and such...I naturally assume it didn't exist on steam..How could it ? And/or, was it on traction power ? If there were always 2 men in a cab why was it even needed as one would see/hear other collapse/moan anyway, no? I guess it shut down traction motors if foot came off....But, then, how long could a human keep a foot in same position, to boot ? How quickly did it activate and how ? What's the scoop here ? Almost seems like a myth....
Diesel locos, early. Had to keep your foot on it....certain time with no foot, loco stopped. I knew inspectors who always found a big rock, brick, or toolbox on the cab floor....guys just set it on the pedal.
Our switchers have them. SW-9's. The old U-33's had them. All Comet 1 & 2 cabcar had them. Now they have an alerter system that makes you do something. Ring the bell, blow the horn, sand, etc. If you don't, a beeping starts. You have to hit a button or a stick. If you don't, the train will automaticly go into penalty. If your fast enough, you can reset on the fly. If not, you reset & take off.
