Here's a more recent, but not so good video that I shot last year. The consist is PAR 1 (FP9), PAR 2 (FP9), NS 4726 (F7B), NS 4720 (F9A), ST 100, ST 101 (Pan Am OCS cars), NS Generator Car, and the NS OCS.

It was leaving out of Ayer, MA (the eastern end of the Pan Am/NS Patriot Corridor) to go to Mechanicville, NY to celebrate the efforts to reopen the Mechanicville intermodal yard (which has become a grassy field since it was closed more than a decade ago). The yard was rebuilt to expand NS's intermodal service into New England. (The yard was once owned by Pan Am. It was transferred to a joint company between NS and Pan Am (Pan Am Southern). Pan Am contributes property, NS contributes money, and they both split the profits)
I was at Shirley, MA (next town over from Ayer) and heard over the radio that the OCS was delayed at the station because PAR 1 had a stuck handbrake. After an hour and a half and no train, all the railfans stood around and held conversations while waiting patiently for the train to radio the dispatcher saying that they were good to go.
The train never radioed the dispatcher, so when it came flying around the corner, we all had to scramble to get rolling and shooting. In my case, I set up my tripod next to a tree. The shadow wasn't over my tripod when I set it up, but when the train came, the shadow had moved, and there was no time to move the tripod.
The detector at Shirley didn't report any defects, but when the train got to Gardner, MA (~10 miles away) the detector went off shouting hotbox. Turns out they decided to drag it, hoping that the handbrake would release itself.
It did release itself afterwards as all the other detectors along the way did not report any defects.
