100% UDEUltimate Deceleration Event Sean Lamb (UDE is a railroad acronym for UnDesired Emergency, as in an event where the brake system on a train is set to the "Emergency" setting, bringing the train to a stop as absolutely soon as possible. Most often a train is set into Emergency when a car is stopped on a railroad crossing or desides to drive around the gates; engineers in this situation are normally granted a psychological leave for a short period.)
