Validation of Track Geometry Input to the Vibration Test Unit (VTU) and the Endurance Capability of the VTU

This report describes a series of tests conducted at the Transportation Test Center, Pueblo, Colorado, to validate two forms of track geometry inputs to the Vibration Test Unit (VTU) in the Rail Dynamics Laboratory, capable of reproducing actual revenue track conditions. The first form consisted of...

Tank Car Damage Assessment Procedure Study

The study concerns the rupture of damaged tank cars which have been involved in railroad accidents. In this regard, a series of impact tests using the FRA/BRL Drop Hammer Facility was performed. The tests consisted of the creation of controlled damage to flat steel plates which had properties...

Safety Margin Testing of a 70-Ton Boxcar with Shifting Plywood Lading: Test Results Data

Tests were performed at the Transportation Test Center, Pueblo, Colorado, in a joint Association of American Railroads (AAR) and Federal Railroad Administration (FRA) effort in the April-May-June period of 1982. AAR objectives were to perform a "pilot" test on the Vibration Test Unit (VTU) as a...

Truck Design Optimization Project (TDOP) Phase II: Performance Characterization of Type I Freight Car Trucks

TDOP/Phase II is part of a series of studies being conducted by the FRA to define the engineering options available to the railroad industry to improve the efficiency and productivity of rail freight operations. As part of this effort, experimental and analytic studies have been conducted to define...

The Wear Behavior of High Rails Tested in the First Metallurgy Experiment, 0 to 135 MGT

In the first rail metallurgy experiment, covering the period from September 1976 to September 1977, 135 million gross tons (MGT) of traffic were accumulated on the Facility for Accelerated Service Testing (FAST) track under two widely different lubrication regimes. The first regime of poor...
