Commuter Ops

Is anyone else concerned about being 1 man only on a train? This is a safety issue in more ways than one. Medical emergency whether it be a customer or crew member, clearing the train before going to yard at night. In some cases it will be too late to help. I find this appalling that the UP and Union have agreed to this. It will only take one incident for the shit to fly. Please correct me if I'm wrong on this issue..
