After passing an empty KCS grain train at Sheldon, 4107 waits for a signal at the reservoir crossing between Sheldon and Fauna. In the previous 30 minutes to this photo, KCS 4107 met the KCS 4575 west, which held the main at Sheldon for a 3 unit BNSF light engine move from Dayton. Not a UP engine here on the present day UP, ex SP Lafayette sub.
