Abstract

A modern rail rapid transit system is a complex combination of many technologies. Systems involve tunnels and elevated structures, tracks and switches, complex maintenance facilities, stations, security systems, fare collection systems, train control systems, and rolling stock.

The history of the development of subway cars is as interesting as the history of the transit system on which they travel. From the earliest days of rudimentary cars hauled by cables, and later by steam engines, to the most recent subway cars with a new generation of technology, the subway car is the place where transit patrons spend most of their time. It is their primary interface with the system. Thus, the design and operation of subway cars is critical to the user’s riding experience, and critical to the proper operation of the system.
