On the SL #2 yesterday, after being stuck waiting for freight trains just east of the HOU station, we took a different route than what shows on the Amtrak route maps. Instead of going through Dayton, Liberty et al, we went on a north track through through Kennefick, Hardin and so on. There are no stations or stops between HOU and BMT so I doubt most of the other passengers even noticed but it surprised me. I wondered if it was due to the freight traffic on the usual route; I suppose this is a fairly common occurrence?
