FEC ordered 24, road numbers 411–434.
Note the section crew just past the crossing. I was listening on the scanner and after the train passed I heard them call the dispatcher and tell him they were going back to work repairing the broken rail. It is single track here, just north of the Port Sewall passing track.
Bonus: If anyone is interested "A Railfan's Guide to the FEC, Version 32A, prepared 7/25/98" is available here.
