I have been stalking trains on the CSX mainline for several years, originally anything that passed, but more recently only Amtrak. #98 and the Autotrain northbound (southbound trains go through too early). Twice, I have seen a 'passenger' train go through traveling south, at a time when there was not supposed to be a train traveling that direction. The first time, I just thought that someone was really late. The second time, I realized it was not Amtrak at all, but an all dark blue train with CSX on the sides. I have wondered what it's purpose might be..as surely, CSX executives would not be caught traveling any way other than first class air...It was not a decrepit work train. Tonight, as I watched 98 crawl through, certainly not doing the usual 79mph, I counted cars as I always do, and on the rear were two excess coaches, but they were not Amtrak stock. They were dark, probably blue but at 8:30pm it is hard to distinguish blue from black...No lights on, I could not see well enough to see if they were labelled CSX. Any ideas? CJ
