 Light Road Transit



The New York City Transit System may be one of the World’s most challenging, due to its high Volume of passengers looking for reliable, safe and comfortable daily transportation. Kawasaki’s R142A subway cars are some of the most technologically advanced cars in the system, applying world-renowned Kawasaki engineering to meet and exceed NYC riders' needs
.

There are now 520 R142A cars on the NYCT system. Each shows Kawaski's innovation as well as attention to customer's needs, with special features including automatic announcements, electronic visual messages, a passenger emergency intercom system and wider doorways to enhance rider safety and comfort. Passenger feedback says riders are as pleased with the cars as the NYC transit authorities.


In addition, an advanced monitoring and diagnostics system helps the train operator safely and efficiently run and monitor all vital trainline systems. The result is an important one- maintenance is low and the cars rarely break down.

 
 Key features of the R142A cars include:
 

Bright lighting

Clear electronic visual message displays and audio         announcements

Wide double doorways positioned to maximize passenger         exiting and entering speed

Innovative heating, ventilation and air conditioning systems         for maximum comfort

Computer network-controlled propulsion and braking system         delivers a smooth ride
