Sergeant Schwartz was a supporting villain of the movie The Train.
Schwartz was a German NCO serving under Colonel von Waldheim. He was stationed up front in the locomotive where he kept an eye on Labiche and Didont. He was knocked over the head with a shovel and then thrown off by Labiche, but survived and later rejoined von Waldheim and Major Herren. When the train broke down and Herren took command from the obsessed von Waldheim, Schwartz ordered his men to execute the French hostages, before leaving with the others.
