When Doc and Marty commandeer the locomotive they tell the train crew to uncouple the cars from the tender. The couplers, however, are modern AAR-type knuckle couplers, the earliest versions of which weren't adopted by US railroads until after an act of Congress in 1893. Most couplers prior to then, and even for some time during the transition period, were the older, more-dangerous link-and-pin design.
