This is such a disgrace to our country's infrastructure. I divide my time between Pittsburgh and Washington DC, with apartments in or near downtown in both cities, and Amtrak is by far my preferred travel mode. It's a beautiful journey, in my opinion one of the prettiest (and most underrated) journeys on Amtrak. I don't even care that the train to DC is scheduled to leave Pittsburgh at 5:20 a.m.; I could leave home at 5 a.m. and catch it! But notice I said "scheduled to leave" at 5:20 a.m. It hardly ever does. I've gotten used to 1- or 2-hour delays, but 5 hours is obviously unacceptable. Until the NS work gets done and the schedule regains some semblance of reliability, I've switched to bus, car, and plane, all of them decidedly second choices.
Returning from DC I can usually expect the Capitol Limited to leave DC and even arrive in Pittsburgh reasonably on schedule. The massive delays are west of Pittsburgh.
