| I don't usually recall UP when I think of slugs on the road- certainly not like, say CSX, but here's UPY940 on the head end of four-car local "39" at Polo MO. It's one of only two of model S6-1B on the road. A new crew has just boarded and they will soon head for Trenton. The signals in the background protect the junction with the ICE. |
