OMAHA, Neb. (AP) — Union Pacific has converted a boxcar into a mobile classroom that it will use to help teach emergency responders about railroads.

The Omaha, Nebraska-based railroad says the boxcar classroom will join its fleet of training equipment it uses with emergency responders.

Union Pacific vice president Bob Grimaila says the classroom will make it possible to expand the number of classes offered each year.

Already, Union Pacific trains about 2,500 local, state and federal emergency responders each year.

The classes give emergency responders a chance to see railroad equipment up close and better prepare for the possibility of a derailment.
