NS C07 is a transfer local between Shire Oaks, PA on the Mon Line and Conway Yard on the Fort Wayne Line. Occasionally, as with today, the train also is used to transfer power between the two yards, the former of which originates one other local and coal trains for the former Monongahela Railroad. Typical local power is usually a SD40E/SD60E or a pair of SD60Es.
We also see a hi-rail truck that hurried to get out of the way of NS intermodal 20R.

Catch 2: Hi-rail rail truck. (1:18) I think they were out repairing welds on a track section, because there weren't any other crew trucks or boom-equipped vehicles.
