In my talking with a MK CM the other day about when the railroad will reopen - she was being trained as a conductor, after first considering being an engineer/fireman. She said that she didn't know when it will reopen, not do any of the team leads.
What was interesting is when I asked about the training to be an engineer/fireman, I asked if they needed to be licensed. When I worked at a steam railroad in the NE, we had to have state licenses in the operations of boilers. She said there wasn't any state licensing requirements, that the engineers/fireman undergo local training, with no test.
