Passenger Train Emergency Systems: Single-Level Commuter Rail Car Egress Experiments

The Federal Railroad Administration (FRA) is investigating how to improve rule provisions addressing the safe, timely, and effective evacuation of intercity and commuter rail passengers in various emergency scenarios. A variety of evacuation concepts, strategies, and techniques for applicability...

Dynalist II- A Computer Program for Stability and Dynamic Response Analysis of Rail Vehicle Systems : Volume II : User's Manual

A methodology and a computer program, DYNALIST II, have been developed for computing the response of rail vehicle systems to sinusoidal or stationary random rail irregularities. The computer program represents an extension of the earlier DYNALIST program. A modal synthesis procedure is used...

Universal Safeguard Cab (Idler Locomotive Cab) Concept Development, Volume II: Demonstrator Alternatives and Implementation

Volume II of this report presents analyses of seven different demonstrator configurations, four in the hi-rail dual mode, and three in the rail-bound mode. The examination of the alternatives was carried out in terms of four main criteria: fidelity to the concept of the Universal Safeguard Cab,...
