Long-Travel Draft System Impact Testing

RAILWAY AGE, MAY 2022 ISSUE: Under the Association of American Railroads (AAR) Strategic Research Initiatives (SRI) program, MxV Rail (formerly TTCI) is conducting research to characterize, evaluate and improve the performance of long-travel draft systems. Draft systems protect railcars as coupler forces are transmitted through a train by controlling relative motion between coupled cars and absorbing energy during impacts.
