The couplers automatically lock when cars are pushed together, but workers must go between cars to hook up the air lines for the pneumatic brakes and connect cables for head-end power and other communications. To separate cars, a worker must use a lever to move the locking pin that keeps the coupler closed.
Need safety checks on locomotive and a sufficient number of cars. Starting on January 1, 1898, unlawful for a common carrier used for interstate commerce to use locomotive engine not equipped with a power driving-wheel brake and appliances for operating the train-brake system.
It automatically locks the couplers on cars or locomotives together without a rail worker having to get between the cars, and replaced the link and pin coupler, which was a major cause of railroad worker injuries and deaths. The locking pin that ensures Janney couplers remain fastened together is withdrawn manually by a worker using the "cut ...
Wheel Slide Protection (WSP) equipment is generally fitted to passenger trains to manage the behavior of wheel sets in “low adhesion” (reduced wheel/rail friction) conditions. It is used when braking and may be considered analogous to anti-lock braking (ABS) in cars. The system can also be used to control (or provide an input to) the ...
The link-and-pin coupler consisted of a tube-like body that received an oblong link. During coupling, a rail worker had to stand between the cars as they came together and guide the link into the coupler pocket. Once the cars were joined, the employee inserted a pin into a hole a few inches from the end of the tube to hold the link in place.
A flat spot occurs when a rail vehicle's wheelset stops rotating while the train is still in motion, causing part of the wheel to ablate against the hard steel of the rails. Flat spots are usually caused by use of the emergency brake, or slippery (low-adhesion) conditions that cause wheels to lock up while the train is still moving. Flat spots ...
Narrow gauge flat wagons, 750 mm (2 ft 5 + 1 ⁄ 2 in).Note the single buffer with a hook on the right side and a chain on the other. On some narrow-gauge lines in Europe, and on the Paris Metro, a simplified version of the loose-coupler is used, consisting of a single central buffer with a chain underneath.
A magnetic track brake (Mg brake) is a brake for rail vehicles. It consists of brake magnets, pole shoes , a suspension, a power transmission and, in the case of mainline railroads , a track rod. When current flows through the magnet coil, the magnet is attracted to the rail, which presses the pole shoes against the rail, thereby decelerating ...
