Earlier today, well, yesterday (April 12th), I was on Amtrak Regional Train 177 from Boston, getting of at NY Penn. Shortly after the Stamford, CT station, the train slowly came to a halt, and the lights suddenly went out in the Amfleet I cars. Now, the lights often do go out do to the different power sources and the HEP Inverter having to be reset, but once the train stopped, it took a few seconds for the lights to go out. After about one minute of waiting, a conductor came over the PA system and announced that the engineer was "recycling the engine." Now, I'm guessing this means resetting the HEP inverter. After about 2-3 minutes, the lights came back on and we began to go again. Is there any explanation to why this would happen? I'm not talking about why the train stopped, it was probably a MNCR train ahead of it, but why the lights went out and why it took so long to get everything going again. Thanks.
