Southern Railway (abbreviated SR) is one of the 18 zones of Indian Railways. It is headquartered at Chennai and operates across the states of Tamil Nadu, Kerala, Karnataka , Andhra Pradesh and the union territory of Puducherry. It maintains about 5081 km of railway lines and operates 727 railway stations.
The origin of the Southern Railway can be traced back to the mid-19th century. In 1835, the first railway track in India was constructed in Madras and became operational in 1837. The Madras Railway was formally established later in 1845. The Southern Railway was created on 14 April 1950 by merging three state railways, namely, the Madras and Southern Mahratta Railway, the South Indian Railway Company, and the Mysore State Railway and became the first railway zone of the Indian Railways.
History

The history of the Southern Railway can be traced back to the Madras Railway. In 1832, the proposal to construct the first railway line in India at Madras was made by the British. In 1835, the railway track was constructed between Little Mount and Chintadripet in Madras and became operational in 1837. The Madras Railway was established later in 1845 and the construction on the first main line between Madras and Arcot started in 1853, which became operational in 1856. In 1908, Madras Railway merged with Southern Mahratta Railway to form the Madras and Southern Mahratta Railway.
In 1944, all the railway companies operating in British India were taken over by the Government. Post Independence, various re-grouping proposals were studied as there were 42 different railway systems. In December 1950, the Central Advisory Committee for Railways approved the plan for Indian Railways into six zonal systems and the Southern Railway zone was created on 14 April 1950 by merging three state railways, namely, the Madras and Southern Mahratta Railway, the South Indian Railway Company, and the Mysore State Railway.
Organisation

Southern Railway zone covers the states of Tamil Nadu, Kerala, Puducherry and a small portion of Andhra Pradesh. Andaman and Nicobar will form part of the zone once the proposed new railway line between Port Blair and Diglipur becomes operational.
The Southern Railway is headed by the General Manager, assisted by an Additional General Manager. Southern Railway is headquartered in Chennai and is divided into six divisions namely Chennai, Tiruchirappalli, Madurai, Palakkad, Salem and Thiruvananthapuram.

Operations and infrastructure
The zone operates both passenger and freight trains. Various classes of passenger trains including Vande Bharat Express, Shatabdi Express and Tejas Express are operated by Southern Railways. Freight operations include container traffic from the ports, coal bound to the thermal power stations, oil and petroleum products from refineries, cement and food grains. Most of the lines inside ports, thermal stations, manufacturing industries and owned by the respective companies and the zone provides a link connecting to its network along with the wagons and locomotives. The zone has a larger proportion of passenger traffic compared to freight. There are about 727 stations on the Southern railway network.
Locomotives
Southern Railway utilizes various classes of electric and diesel locomotives to haul the trains. Steam locomotives are used by the Nilgiri Mountain Railway. The zone has three electric locomotive sheds and four diesel locomotive sheds.
| Name | Location | Type | Locomotive class | Count |
|---|---|---|---|---|
| Electric Loco Shed, Arakkonam | Arakkonam | Electric | WAP-4, WAG-5, WAG-9 | 184 |
| Electric Loco Shed, Erode | Erode | Electric | WAP-4, WAP-7, WAG-7 | 211 |
| Electric Loco Shed, Royapuram | Chennai | Electric | WAP-5, WAP-7 | 122 |
| Diesel Loco Shed, Ernakulam | Ernakulam | Diesel | WDM-3A, WDG-3A, WDM-3D, WDG-4, WDG-4D | 39 |
| Diesel Loco Shed, Erode | Erode | Electric | WAP-1, WAP-4, WAG-5, WAG-7 | 145 |

| Coonoor Loco Shed, Coonoor | Coonoor | Steam, Diesel | X Class, YDM-4 |
Maintenance and workshops
Southern Railway maintains wagon and locomotive workshops at Perambur, Chennai and Ponmalai, Tiruchirapalli, engineering workshop at Arakkonam, carriage maintenance workshops at Basin Bridge and Egmore and a signal and telecommunication workshop at Podanur, Coimbatore. It has three EMU car sheds in Chennai at Avadi, Tambaram, Velachery and MEMU sheds at Kollam and Palakkad. Southern Railway maintains trip sheds at Basin Bridge, Egmore, Tondiarpet and Jolarpettai. Southern Railway operated ticket printing presses at Royapuram, Thiruvananthapuram and Tiruchirappalli, but these have been phased out due to digitization.
Railway coaches and wagons
Southern Railways uses both ICF coaches and LHB coaches for its trains. ICF coaches manufactured by the Integral Coach Factory in Chennai have been used predominantly for over sixty years since the formation of the zone in 1951. The ICF coaches are slowly being replaced by newer LHB rakes which provide better passenger comfort and safety.
