The URR switchers pull a heavy steel slab train through J Interlocking while Q353 heads west on CSX.
The only green engine on the roster, URR #17 leads the afternoon slab train from the Edgar Thomson plant.
After ducking underneath Bettis Road, #17 will enter a long tunnel and emerge in Dravosburg. From there it's a short trip to the Irvin Works where these slabs will be turned into steel coils.
After taking a train to USX's ET plant in Braddock, URR 17 has returned to Duquesne for its next assignment.
A rare bird on the Union, the only engine that was painted green. Photographer is standing in Duquesne, the train is in Braddock.
