This new tested braking technology could significantly enhance rail safety and efficiency. It offers major benefits in freight train handling, car maintenance, fuel savings and network capacity.

With the current braking system, developed back in the 1870’s, freight train cars brake individually, at the speed of the air pressure moving from car to car, along trains that are often well over a mile in length.

This conventional braking contributes to excessive in-train forces, challenges in train handling, longer stopping distances, and safety risks of prematurely depleting air brake reservoirs. These problems are greatly reduced in the ECP brake mode of operation,
during which all cars brake simultaneously, driven by an electronic signal.

ECP systems simultaneouslyapply and release freight car airbrakes:

• Through a hard-wired electronic pathway down the length of the train;
• No delay, and no run-in of slack from the rear of the train.

Joseph Boardman, FRA’s administrator, said he believes the technology can prevent accidents, in part because ECP brakes allow the engineer to “back off” braking effort to match track grade and curvature, without completely releasing the brakes — with these significant added benefits:

• Saves fuel and reduces emissions;
• Reduces wear / stress on wheels and brake shoes;
• Reduces chance of run-away from overheating of the brake shoe / wheel interface.

Futhermore, ECP brakes provide a tool to manage in-train forces and reduce train handling derailments as well as reduce chances of runaway trains.

The FRA said the brakes are designed to allow trains to travel up to 3,500 miles without inspections which is more than double the distance normally allowed by the government.

The agency adds that the waiver allows it to gather data to be used in developing a proposed rulemaking on ECP brakes.

Several conditions were placed by the FRA on the waiver approval, including requirements that the railroads (1) clearly define a process for handling brake problems discovered en route, (2) ensure that qualified individuals perform ECP brake inspections and that (3) they provide appropriate training to crew members.

“A safe railroad begins with safe track, but it doesn’t end there,” Administrator Boardman said. “Railroads needs to embrace a ‘culture of safety’ and find new ways to prevent the kind of accidents that have disrupted lives and commerce and shaken our confidence in the safety of tracks,” he stated before climbing aboard a federal track inspection vehicle called the T-16 to observe an inspection of track from Albany to Schenectady.

Boardman explained that during the next two days the T-16 will inspect the heavily used CSX tracks from Albany to Buffalo, including the lines to Niagara Falls and to Ripley at the Pennsylvania border. The itinerary will take the T-16 through Oneida, Rochester, and Cheektowaga where major derailments have occurred in recent days and months. The inspection will measure whether the two track rails are level and if the width between the rails is acceptable to avoid derailments.

The Administrator added that last month he directed another federal track inspection vehicle, known as the T-18, be used on CSX tracks in New York. The T-18 will inspect for weaknesses in the track structure such as bad crossties or poor connections between the rail and crosstie that could cause the rails to dangerously widen when a train rolls over that section of track.

And, in order to build a baseline for evaluating a railroad’s ‘culture of safety’, the FRA will begin a quality assessment of the CSX rail inspection program, starting in New York and then extending it to their entire network. Boardman said he is interested in learning what criteria CSX uses to determine how frequently the company inspects its own tracks beyond current federal requirements, if track improvement decisions are made differently when a line has hazardous material or passenger rail traffic, and how track problems are identified and resolved including the use of technology to find flaws. The results of this risk reduction approach will be used to guide similar FRA evaluations of other railroads, he added.

Boardman also said that he met with CSX senior executives to discuss the railroad’s recent safety record and the results of a focused inspection on CSX property conducted in January. In addition, FRA is performing a safety review of railroad bridges in western New York.
