Coaching Stock

The different types of passenger coaches include the electric multiple units that are a part of suburban trains and conventional coaches such as II class, I class, II sleeper, ac three tier, ac two tier and ac I class coaches.

In 1994-95, Indian Railways had a stock of about 3600 EMU coaches and 30,000 conventional coaches capable of carrying a total of about 3.7 million passengers. These coaches have three basic structural designs.

(a) Integral coaches built by the Integral Coach Factory (ICF), Perambur, Chennai

(b) Integral coaches built by Bharat Earth Movers Ltd (BEML), Bangalore

(c) Non-integral wooden body coaches made in accordance with the Indian Railways standard design (IRS)

Some of the salient features of these three types of coaches are given in Table 24.8.
