HQ-2017-1232 (Finalized)

On October 13, 2017, at approximately 5:00 p.m. MDT, a single rail car rolling uncontrolled impacted a BNSF Railway Company (BNSF) “road switcher” Freight Train R-MON8151-13I (train 1) as the train was traversing from the Red River Industries' track onto BNSF's Main Track No. 2. he side collision...

HQ-2017-1212 (Finalized)

On July 2, 2017, at 2:29 p.m., PDT, northbound Amtrak passenger Train 506 derailed after running past the red signal protecting BNSF Railway (BNSF) Bridge 14, and hitting the derail on Main Track No. 2, in Steilacoom, Washington. Locomotive No. Amtrak 467 came to rest on its side and three Talgo...

PTC Test Bed Siding Signal Upgrade at the Transportation Technology Center

The Federal Railroad Administration (FRA) contracted Transportation Technology Corporation, Inc. (TTCI) to continue work performed from February 2013 through December 2014 to upgrade the infrastructure and testing capabilities of the Positive Train Control (PTC) Test Bed by converting the existing...

The Cab Technology Integration Lab: A Locomotive Simulator for Human Factors Research

The paper describes a new human factors research capability for the US Federal Railroad Administration (FRA)—The Cab Technology Integration Laboratory (CTIL). The FRA sponsored the development of the CTIL in order to assess locomotive crew performance with the integration of new market controls,...

Cognitive Distraction & Attentional Error: Bringing Science to the Rail Industry

Accidents in commuter rail operations point to the need for better understanding of the contributory role of operator distraction in rail safety. This presentation discusses need for further study and was part of early work leading to two simulator studies done in this area (documented in FRA/...

Human Factors Evaluation of an Experimental Locomotive Crew Station

A human factors evaluation of an experimental engineer control system was conducted by the John A. Volpe National Transportation Systems Center (Volpe Center) using a locomotive research simulator—the FRA’s Cab Technology Integration Laboratory (CTIL). The primary objective of the evaluation was to...

Moving Map Displays: Using CTIL and Eye-Tracking Technologies to Measure Operator Glance Durations and Performance in Locomotive Cabs

Distraction is a growing problem in the cabs of modern locomotives. The 2008 commuter train collision at Chatsworth, CA resulting in 28 fatalities, points to the dangers of distractions inside the cab. The NTSB investigation determined the operator was texting while in control of the train, and...

Development and Evaluation of a Moving Map Display for Rail Applications

This report describes the development and evaluation of a prototype real-time moving map display to support engineer situation awareness and safety performance for future U.S. high-speed rail applications. The development started with a hybrid Cognitive Task Analysis to develop Information and...

Modeling Human-Automation Function Allocation Effectiveness in Rail

Introduction of automated systems in locomotive cabs changes the scope and complexity of the human crew’s work. This research seeks to provide a methodology to design and evaluate new roles for humans and automation systems. A hierarchical task model was built and used to inform the design of an...

A Human Factors Evaluation of an Experimental Locomotive Engineer Crew Station

Conventional control stands for trains have evolved from models of locomotives dating back to the 1950s, before extensive automation and computerized displays existed. The introduction of such features increases the scope of the user interface and indicates a need for a more involved design...
