On the low level tracks that go underneath Capitol Hill, not only do you have Amtrak's own trains. During the week, VRE trains use those tracks as well. Marc trains do too. I boarded a MARC train once from those platforms.
I'm with Tadman on this. Amtrak does very little right. For instance, they ordered some new Viewliners. How many years behind is this order? Apparently the vendor works with extreme slowness, and Amtrak seems to have no recourse. Why is that?
As far as what is laughingly called customer service, I doubt if any pre-Amtrak railroad was as bad as Amtrak. We see no reason why Amtrak engine changes should take as long as they do. If Europe, with their strong unions and commitment to safety, can do fast engine changes, then Amtrak should send some observers across the Atlantic to see how they do it there, and how we could do better. If the current blue flag rules are too cumbersome, we should learn from Europe. Anyway, can we find out how much of the slowness results from cumbersome rules, and how much from Amtrak management having no interest in better or faster service?
It breaks my heart to see American passenger service, which was the world's best when I was a kid, devolving into something that would be an embarrassment to many Third World countries.
