Transportation Technology Center, Inc. conducted an impact test with two F40 locomotives to evaluate the performance of both vehicles under dynamic conditions. One 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 January 23, 2019, at the Transportation Technology Center in Pueblo, Colorado. The stationary locomotive was impacted by the CEM-equipped locomotive at 19.3 mph. The impact-initiated deformation on one set of anti-climbers and activated the PBC. However, the remaining impact energy was insufficient to initiate shearing in the shear bolts.
