I wonder if there might be a bit of switching choreography required, if a unit in the middle of a train dies. And what if an axle jumps the rails ? What does rerailing look like ?
I know these are all solved issues for railroads, but I wonder if tunnels and lack of lateral access by heavy equipment makes a difference.
