Took 91 - 92 today WPK-TPA-WPK. Also had tickets TPA-Sebring-TPA to extend the trip, but we were 4 hours+ late on the WPK-TPA leg and would have gotten into Sebring at least a half hour past the 92 departure NB, so elected to just stay in Tampa. But then 92 was about two and half hours late, so we would have been ok to go to Sebring (hindsight). I know the 91 delay was at least partly from the WAS derailment. Wonder if Miami Joe (or anybody else) would know why 92 was so late leaving MIA? I heard it was equipment trouble but wonder if somebody could amplify. It was a nice trip, and especially nice to ride the new route, but it sure shot our schedule out the window. The only benefit to the lateness was that I knew last night that 91 was already 3.5 hours late, so we didn't have to get up quite so early (normal departure from WPK = 0755)
