Abstract:An impact test with a F40 locomotive and a M1 passenger car was conducted to evaluate the performance of the vehicles under dynamic conditions. The locomotive was retrofitted with crash energy management (CEM) components – including a push-back coupler (PBC), deformable anti-climbers, and a sliding lug connected to the draft pocket with a set of shear bolts. The impact test was performed in November 2021 at the Transportation Technology Center in Pueblo, Colorado. The M1 passenger car, backed by two empty hopper cars, was impacted by the CEM-equipped locomotive at 32.8 mph. The impact-initiated deformation on one set of anti-climbers, activated the PBC, and sheared all the shear bolts.
