"Today's" 29 hasn't left yet! The 29 you're looking at is the one that left WAS yesterday at 4:05PM and was delayed, if you checked the status of 29 last night then you would have been checking the same train as you did this morning.
Thanks, ALC -- I guess what I meant to say was, the train scheduled to arrive today is about 3.5 hours late, and the train scheduled to arrive yesterday was about 10 hours late as discussed above. So since it appeared that the delay also affected Thursday's train, in addition to Wednesday's train, I was curious as to whether or not it would also affect Friday's train.
But, thanks for the prompt reply.. I am Select Plus on Amtrak but usually just hang out on the Northeast Corridor, so I'm not too familiar with the long distance trains. I usually post on Flyertalk (I recognize a few names over here from FT, such as AlanB) but knew that I would get a much faster response here.. so thanks again!
