Train Accident Reconstruction
and 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.

Combining Science and Experience in Train Accident Reconstruction

JRLA uses physics-based analysis, computer modeling, event recorder data, and site and train data to provide detailed reconstructions of train braking distances, speed profiles, times, positions, slack action, and sequences of events. We can analyze train and railcar dynamics that are part of an accident or derailment. We can also evaluate operator actions and various train handling and accident-avoidance scenarios.
