Fueling the Big Locomotives

As we drove our RV across the wide open spaces of Wyoming, we followed the railroad tracks for quite a while.

This was taken as we passed by the railroad yards near Guernsey, Wyoming (just off Highway 26). Took this through the windshield of our RV, and it has been processed with GIMP.

They are fueling the road engines from tanker trucks. I think that these railroad yards do not have separate fuel tanks (or else don't have enough capacity). There were many other trains being fueled in this yard this way.
