Abstract:The project evaluates wheeled mobility device (WhMD) securement and occupant restraint on passenger trains. Researchers tested three off-the-shelf wheelchair securement systems in a train-to-train collision as a proof-of-concept to mitigate the effects of second impact velocity. The tests evaluated the performance of the securement devices regarding human injury, compartmentalization, structural integrity, and attachment. The team conducted a full-scale train-to-train impact test at the Transportation Technology Center in Pueblo, Colorado, on August 11, 2022. Three WhMD occupant protection experiments were installed in the M1 passenger cars behind the Crash Energy Management (CEM) locomotive in the moving consist. These experiments included different types of wheelchairs, restraint systems, and Hybrid III 50th percentile male (H3-50M) anthropomorphic test devices (ATDs) equipped with instrumentation to measure force, moment, acceleration, and displacement data. All the backboards, wheelchair securement, and occupant restraint systems used in the experiments maintained their structural integrity and remained attached to the carbodies during the tests. The injury values measured by the H3-50Ms were well below the limits and met the performance requirements specified in the APTA seat and table standards.
