FRA Supports Improved Train Braking System; Humphrey Technology is Key
Date: June 2007 The Federal Railroad Administration (FRA) is proposing revised federal rail safety regulations to facilitate the installation of Electronically Controlled Pneumatic (ECP) train braking systems capable of preventing derailments and shortening train stopping distances. Working closely with the manufacturer of this system, Humphrey's Engineered Solutions Team developed a compact valve manifold assembly that met the manufacturer's critical requirements for performance, reliability and simplicity.
ECP brakes are applied uniformly and virtually instantaneously on every rail car throughout the train, rather than sequentially from one rail car to the next as is done with current air brake technology. As a result, the system provides improved train control when braking and can reduce stopping distances up to 60 percent.
The new system utilizes proven Humphrey poppet-type cartridge insert valves that are pilot operated by low current consumption Humphrey solenoid valves. Air passageways and port locations are mated with the existing air brake control system to maintain fail-safe operation -- an absolute requirement for railroad application.
