So, most of us know what this device is and how it works as well as its purpose. My question is, do you think it is effective? I mean, I agree that it makes the T/Os keep control of the train since they have to hold it while operating a train, but what if the operator becomes incapacitated and falls on the controls holding the switch down? The train will keep going. Don't you think this is a shortfall of the device?
Thanks
