Train Accident Reconstruction &
Train Braking Expert

JRLA reconstructs railroad accidents involving freight, passenger, industrial, and excursion trains at crossings, stations, and interlockings, in yards, urban areas, and along track routes.

JRLA uses a combination of physics-based analysis, computer simulation and modeling tools, and event recorder data to calculate train braking distances, speed profiles, times, slack forces and accelerations, and sequences of events. We can analyze train and railcar dynamics leading up to an incident or derailment. We can also evaluate operator actions and analyze various train handling and accident-avoidance scenarios.
