So it's 8:06 pm, and I'm sitting in the dark on NER 186 a little south of milepost 99 somewhere between BWI and West Baltimore. we were going great and then the lights went out and we coasted to a stop. Announcement made that we were having mechanical problems...I'm in first car and crew hanging out were talking about how the couldn't keep the circuit breaker closed. Lights went back on for a moment, and then went off again. Sounds like the conductor was calling Tech Support (at Siemens?) and was given some codes, presumably for the engineer. Nice chilly night, reporting 12F at BWI. So far the coach is still warm, but I hope they get this fixed or offload us into a rescue train soon!
