The more interesting question is what happens to the steam generator exhaust when the GG1 is stopped in an enclosed station. Most often the GG1 is in the open, but occasionally it must be stopped in the enclosed area. The only specific area I can think of is inbound into Penn Station from Jersey. The open area was on west end and east end was completely underground. Also thru the Hudson and East river tunnels. Did the engineer or firemen simply turn off generator or???
