These CN cars were similar to conventional boxcars, except they had a second floor and doors at both ends of the car instead of the usual side doors. They were huge by the standards of the time; the cars were 75 ft (22.86 m) long and could carry eight vehicles.
Like all Janney couplers, the Tightlock is "semi-automatic". 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 ...
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 The locking pin that ensures Janney couplers remain fastened together is withdrawn manually by a worker using the "cut ...
While acceptable for mineral cars, this coupling made for an uncomfortable ride in passenger coaches, so the chain was improved by replacing the center link with a screw with a left-hand thread on one side and a right-hand thread on the other. In the center of the screw is the handle housing with a hinged ball handle attached.

The Scharfenberg coupler [1] (German: Scharfenbergkupplung, abbreviated Schaku) is a commonly used type of fully automatic railway coupling.. Designed in 1903 by Karl Scharfenberg in Königsberg, Germany (today Kaliningrad, Russia), the coupler has gradually spread from transit trains to regular passenger service trains, although outside Europe its use is generally restricted to mass transit ...
The original law was amended by a subsequent act in 1903, whose first section provides that the requirements of the original act respecting train brakes, automatic couplers, and grab irons shall be held to apply to all trains and cars used on any railroad engaged in interstate commerce, unless a minor exception were satisfied.
These were picked up by sensing coils mounted on the leading bogie. One rail supplied safety information, which was received continuously. Any failure to obtain this data resulted in a trip-valve operating, which stopped the train. The second rail supplied signal commands, which included speed signals and instructions to start and stop the train.
