After receiving a Track Authority to work within the limits of a Roadway Worker (Track Foreman), BPRR PSDB-1 (running as NS KH32 on NS trackage) backs into the Signaled Siding at SOUTH DRIFTWOOD interlocking behind a GP38, SD40-3, and SD45-2 (the latter two both variants of ex-SP SD45s). This train originated at Du Bois, and on this day has 25 cars for NS and will be picking up 37 on their own. Most of this traffic is frac sand and less-than-trainload coal.
