Phil,
Both prime movers have water damage to an unknown degree. I guess 200" of rain yeary and an open stack is not a good thing. SVRR did get a grant towards the 720, and copper prices have dropped making new wire and cable a little cheaper. There are a few volunteers working on 720, but weather is now an issue.
8:30 pm and Baker City has been -11 to -8 over the last hour. Neither 50T was built with cab heaters, it might be a good idea.
We were able to put a regular locomotive cab heater in the 1203, no luck on these because they do not have enough electrical output.
