Back in April of 2019 I posted a black and white image of these railroaders as they were comparing their time pieces. I later discovered this color version of that photograph taken a few seconds later. The paragraph below is taken from that original posting and sums up the scene.

In March of 1943, during his visit to the Atchison, Topeka and Santa Fe Railroad, Jack Delano photographed conductor George E. Burton and engineer J.W. Edwards comparing time before pulling out of Corwith Yard in Chicago for their run to Chillicothe, Illinois. Accurate time is vital for train operations, and the conductor will synchronize his watch with an “official” clock prior to a run. The crew members will verify that their watches are matching his watch as well.
