Communication Based Train Control

Communications and train control systems are an essential part of operating and maintaining railroads safely and efficiently. New generation systems can increase capacity, improve service reliability, increase average train speed, reduce congestion, and maximize the effective use of assets while reducing life-cycle costs and increasing safety.

Vehicle Performance Monitoring

What would it be worth to eliminate defective components before they spoil your profits?

When it comes to railcars, planning ahead can mean the difference between controlling your maintenance efforts or maintenance requirements controlling you.

Computer Modeling

By putting TTCI’s vehicle and train dynamics modeling tools to work, users can explore how rail vehicles, components, structures, and systems will behave without ever putting a train on the track.

One of TTCI's greatest strengths is its ability to accurately model the behavior of rail vehicles, components, track, structures, and systems.

Passenger Rail Research

Passenger vehicle testing is about moving people safely, timely, and cost effectively. How safe do your vehicles perform and interact with the infrastructure? How can you optimize your system’s performance? How can you make operations more cost effective? TTCI can help provide answers to these questions.

Instrumentation

TTCI has extensive test instrumentation, data collection and communication, and analysis capabilities that support laboratory and field testing activities around the world.

Typical dynamic vehicle measurements are made with a computer equipped instrumentation car that rides along with the test car, collecting data pertinent to the test. On the track, sensors installed in specific test sections make dynamic measurements, while wayside computers collect the data. Static measurements are made with a variety of precise and specially developed devices. TTCI measurement systems are portable and are frequently mounted on customer locomotives and transit cars.

Rail Defect Test Facility

A program co-sponsored by the Association of American Railroads and the U.S. Department of Transportation, Federal Railroad Administration (FRA) was established to evaluate and quantify the capability of rail flaw detection systems designed to detect rail defects. Under the jointly sponsored program, system performance qualifacation of rail flaw detection systems are scheduled and conducted on the Rail Defect Detector Facility (RDTF), located at the Transportation Technology Center, Pueblo, Colorado, USA.

Transportation Security

One way or another, we are all working to assure our security. Rail freight and passenger transportation systems are working around the clock to protect citizens, infrastructure, and services. Sabotage detection and prevention is now a critical arena for research and development.

Key infrastructure and equipment control centers, passenger stations, rail vehicles, track, yards, bridges, and tunnels are being hardened against potential terrorist threats. Methods for analysis, prevention, detection, and response to terrorism in the rail sector are rapidly evolving. TTCI, the leader in railroad technology, is responding, by offering methods to North American railways for keeping people safe.

 

Wheel Rail Management

North American railroads have about 17‐million tons of rail in some 70,000 miles of track that carries more than 20 million gross tons of rail traffic.

Part One

Wheel Rail Interface Management
Railroad wheels and rails are made of high strength steel. A steel wheel requires very little energy to roll on a steel rail; indeed, care must be taken that a car does not run away on level track on a windy day. This is because the wheel and rail deform very little under load, unlike a rubber tire rolling on asphalt...


Part Two

Wheel Rail Profile Management SFK
Poor wheel/rail contact, particularly in curves, reduces the effective steering capacity of the cars negotiating these curves. This appreciably increases the rolling resistance of trains on curved track, significantly impacting fuel consumption, track forces, and wheel and rail wear...


Part Three

Wheel Rail Contact Inspection System
TTCI has developed an automated wheel/rail contact inspection(WRCI™)system using the Track Loading Vehicle or existing track geometry measurement cars...
