Well, this triggers an all-too-recent memory:
Last year I was riding the Regional when the crew was pulled out of service for a similar rules violation. It was a horrible experience.
From my memory, the train was stopped for about ten minutes before an announcement was made that we were waiting for traffic ahead to clear up. A similar announcement came about ten minutes later. Then, silence for a long time until a crew member came through saying that nobody knew why we were still stopped, and that neither Amtrak nor the host railroad were answering the crew's calls. I think the crew member made a second pass a while later saying the same thing.
Finally, forever later, a crew member came through saying that the train was caught speeding in a restricted zone (I believe), and that the evil host railroad--who were just horrible people, horrible I tell you, doing this to all of the passengers, please start writing your representatives--had called the train on it. We'd be stopped--oh those awful, smelly employees of the host railroad!--until a replacement crew could arrive.
That crew member came through two or three more times, each time trying to whip the passengers up against the evil, dirty host railroad. I kid you not, it crossed the line from inappropriate to downright uncomfortable. I swear the guy looked like he had been drinking...
Sorry I don't know the positions of the crew members that talked to us. There were a few, and the guy who talked to us from admitting the infraction on--the guy who seemed progressively more inebriated--wasn't one of the normal car attendants.
In the end I think we arrived in DC about seven hours late. Despite the magnitude of the situation here, Amtrak wouldn't issue a refund, and I'm not sure the voucher they issued even covered the costs we took on due to the delay.
And that's why my parents have vowed never to ride Amtrak again, and certainly wouldn't support it politically.
