So I'm waiting at Thendara, all ready to get a photo of the #2400 approaching. I hear them blowing the horn, get ready, and, wait, what the...? The #2456 is leading. Did they swap the locomotives at Tupper Lake? Now, wait, the #2400 isn't even behind it. What's going on?
Then I looked and see the #2400 on the tail end of the train and remembered that the tracks at the station in Tupper Lake are all torn up currently for a construction project to add an enginehouse and a storage spur, as well as reconstruct the Tupper Lake wye. That means they can't run power around the train at Tupper Lake, and the next closest runaround track is 15 miles south, at Sabattis. To avoid having to make a 15 mile shove move, they unhooked the #2400 and ran it to the back of the train and led it into Tupper Lake with the #2400 and then had the #2456 pull the train south from Tupper Lake. Since they are going mostly downhill and don't need the power M.U.ed, they just left the #2400 on the tail end. It also explains why they had two crews aboard at Utica: they needed a crew on both the #2400 and #2456 for this maneuver.
So, I grabbed some shots of the #2456 sitting alongside the depot. I looked back and saw that the brakemen were unhooking the #2400, so my hope was that they were going to put #2400 back on the front for the trip south. While waiting, Deandre Walters, one of the Adirondack's engineers that I haven't met before, came up and introduced himself. We've seen each other's names online, but it was nice to put faces to names. His remark on the lashup that he was running was "not the power I was expecting today". According to him, the #3573 had been acting up the day before, so they'd left the #3573 at Thendara and brought the #2400 south, and then the mechanical department had fixed whatever was wrong with the #3573 on Saturday morning and gotten it running to handle the Explorer services.
It started getting near departure time, and they still hadn't run around the #2400, but I was thinking that maybe they wanted to get everybody on and off first, so that the risk of running someone over was mitigated. Well, the next thing I knew, everyone swung aboard and the High Peaks Limited headed south with just the #2456. They left the #2400 up just above the station, with it shut down. I guess they figured they'd leave it up there, to maybe handle the Explorers next week and get the #3573 back to Utica some other time. This made me decide to scratch my plan to catch the train going along the Moose River, since it wouldn't have the #2400 leading like I wanted.
