In an odd place...
Title:  In an odd place...
Description:  Since the local train entered the Cache Valley Branch on Tuesday; progress has been slow and the train has been running behind schedule. Normally the crew would begin their Thursday morning at their office in Logan Utah... However due to delays caused by snow the local train is found here at Lewiston Utah; parked on the spur leading to Presto Products. This photo was taken early morning, the crew hasnt arrived yet; although UP MoW trucks were spotted at the scene presumably for more snow removal work.

Description:  Turns out that around 1:00 pm the lighting on this curve doesnt allow for easy photos of a northbound train. Pity, it looked like a great photo op.
