History and developments 
The foundation stone for the shed was laid on the 25th of December, 1971 by the then Railway Minister, K. Hanumanthaiah. The shed was open for operations in 1975 with a total area of  and covered area of . The shed initially homed 45 of the YDM-4 class metre-gauge locomotives. Three subsequent expansions were taken up which resulted in the holding capacity being increased to 100 metre gauge locomotives (1998), 40 broad-gauge locomotives (1993) and 100 broad gauge locomotives (2000). Infrastructure 
The shed was started as a metre-gauge shed. However with expansion over time, the bays and catwalks were converted from metre gauge to broad-gauge standards to home broad-gauge locomotives. Later, the shed went for a major expansion of its bays at a cost of  to undertake maintenance activity for the unconventionally longer high-speed fuel efficient 4,500-horsepower (3,400 kW) EMD 710 locos (WDG-4, WDP-4B, WDP-4D and WDG-4D), which are homed since July 2011, thus becoming the first-of-its-kind shed in India to maintain such high powered locos, which were extensively utilised for both passenger and freight services. The shed also houses a Diesel Traction and Training Centre (DTTC), opened on 7 April 1988, to impart theoretical and practical training for the newly recruited Assistant Loco Pilots, Engineers and other technical staffs. The centre only one of its kind in the zone also conducts periodical refresher courses for the in-service staffs of Indian Railways, and also too railway personnels from other countries. The DTTC along with Zonal Railway Training Institute (ZRTI), Trichy made a mark by imparting training to women, by which Narayana Vadivu and Jhansi Rani, became the first all women loco crew in the history of Southern Railway zone piloting a goods train on the Chord Line. With Indian Railways inching towards 100% Electrification Mission, two of its Old Metre Gauge bays were converted to New Electrified Broad Gauge ones. Electric Loco trials in these bays with an Erode Shed (EDDS) WAP-4 locomotive, numbered 22273, were conducted successfully on 3rd February 2022, with the commissioning of these E-locos expected anytime soon. Operations 
The shed, headed by Senior Divisional Mechanical Engineer (Diesel), has about 750 employees in different ranks in the day-to-day operations of the shed, which include periodical overhaul, maintenance and repair works. The locos of this shed were thoroughly traverses over entire South India for passenger and freight services. Locomotives Fleet
