UPRR Main Trk and UPRR Siding

May 31, 2011. Napoleon, Missouri.

These markings are on the main track and a side track that are part of the Union Pacific's River Subdivision.


  1. Huh. Interesting. I've never noticed it was marked like that.

  2. I haven't seen this very often. Not sure if it's a common occurrence or not.

  3. CN does something similar, Except its main 1 and main 2., and it usually is written with a paint pen. or maybe it's a marker.
