Jeffrey Kopplin worked for Wisconsin Central Railroad. In January 2014, he was operating a train at the rail yard in Fond du Lac, Wis. In order to bring the train onto the right track, Kopplin had to get out of the train and “throw” a switch.
The weather that morning was severe, with below-freezing temperatures and high winds. Due to the weather, ice and snow had built up inside of the switch. Kopplin attempted to remove the buildup with a broom provided by the railroad, but he was unsuccessful. In attempting to remove the buildup of ice and snow, Kopplin injured his elbow.
A doctor diagnosed his injury with a medial and lateral epicondylitis. Kopplin took time off from work to receive treatment, including a pain-relief injection.
