Passenger Equipment Safety Standards; Front End Strength of Cab Cars and Multiple-Unit Locomotives

This final rule is intended to further the safety of passenger train occupants by amending existing regulations to enhance requirements for the structural strength of the front end of cab cars and multiple-unit (MU) locomotives. These enhancements include the addition of requirements concerning structural deformation and energy absorption by collision posts and corner posts at the forward end of this equipment. The requirements are based on standards specified by the American Public Transportation Association (APTA). FRA is also making clarifying amendments to existing regulations for the structural strength of passenger equipment and is clarifying its views on the preemptive effect of this part.
