10ORGANSATION STRUCTURE

Indian Railways (reporting mark IR) is an Indian state-owned enterprise, owned and operated by the Government of India through the Ministry of Railways. It is one of the world's largest railway networks comprising 115,000 km (71,000 mi) of track over a route of 65,000 km (40,000 mi) and 7,500 stations. In 2011, IR carried over 8,900 million passengers annually or more than 24 million passengers daily (roughly half of which were suburban passengers) and 2.8 million tons of freight daily. In 20112012 Indian Railways had revenues of 1119848.9 million (US$19 billion) which consists of 696759.7 million (US$12 billion) from freight and 286455.2 million (US$4.8 billion) from passengers tickets.

Railways were first introduced to India in 1853 from Bombay to Thane. In 1951 the systems were nationalized as one unit, the Indian Railways, becoming one of the largest networks in the world. IR operates both long distance and suburban rail systems on a multi-gauge network of broad, meter and narrow gauges. It also owns locomotive and coach production facilities at several places in India and are assigned codes identifying their gauge, kind of power and type of operation. Its operations cover twenty nine states and seven union territories and also provide limited international services to Nepal, Bangladesh and Pakistan.

Indian Railways is the world's ninth largest commercial or utility employer, by number of employees, with over 1.4 million employees. As for rolling stock, IR holds over 239,281 Freight Wagons, 59,713 Passenger Coaches and 9,549 Locomotives (43 steam, 5,197 diesel and 4,309 electric locomotives).

The trains have a 5 digit numbering system as the Indian Railways runs about 10,000 trains daily. As of 31 March 2013, 23,541 km (14,628 mi) (36%) of the total 65,000 km (40,000 mi) route length was electrified. Since 1960.

On 23 April 2014, Indian Railways introduced a mobile app system to track train schedules.The first railway on Indian sub-continent ran over a stretch of 21 miles from Bombay to Thane. The idea of a railway to connect Bombay with Thane, Kalyan and with the Thal and Bhore Ghats inclines first occurred to Mr. George Clark, the Chief Engineer of the Bombay Government, during a visit to Bhandup in 1843.Indian Railways runs around 11,000 trains every day, of which 7,000 are passenger trains.

191.1 Zones of Indian RailwaysIndian Railways is divided into several zones, which are further sub-divided into divisions. The number of zones in Indian Railways increased from six to eight in 1951, nine in 1952 and sixteen in 2003 and now seventeen. Each zonal railway is made up of a certain number of divisions, each having a divisional headquarters. There are a total of sixty-nine divisions.Each of the seventeen zones is headed by a general manager who reports directly to the Railway Board. The zones are further divided into divisions under the control of divi
