The Amtrak Selkirk Branch Qualification train, CSX P924-30, was just a pair of engines and a coach on July 30, 2022, and is probably one of the smaller consists to cross the former New York Central Alfred H. Smith Memorial Bridge Castelton Bridge. Regular passenger service here ended in 1979 with the reinstallation of the Post Road Branch and rerouting of the Lake Shore Limited.
Railroads Cooperate. After some debris fell from Central Warehouse in Albany, New York, and the subsequent need to asses the possible instability of the building, Amtrak service was been suspended between Albany-Rensselaer and Schenectady, New York since the last train, Train 49 (Lake Shore Limited), passed on Thursday night(July 29, 2022) until Monday August 1, 2022 when Train 48 (Lake Shore Limited) crossed the Livingston Avenue Bridge. Minor repairs were made to the building, and further discussion is being carried on about next steps.
In the meantime, CSX cooperated with Amtrak to begin qualifying Amtrak crews on a diversion route normally only used by freight trains. When will diversion trains run? How many? How long will this go on? These are all excellent questions without definitive answers at the moment.
