Services
DTC has an extensive network of bus routes spread all over Delhi. A few routes traverse the neighbouring cities of Noida, Ghaziabad, Gurgaon, and Faridabad. As of June 2023, of the 606 total bus routes in Delhi, 259 were operated by DTC, 209 were operated by DIMTS, and 138 routes were operated on by both the authorities under the Department of Transport's 'Unified Time Table'. These routes are serviced by 7,135 buses, with 4,088 of them under DTC, out of 37 depots and 3 ISBTs. The average number of trips in FY 2021-22 was 31,084 per day. The number of routes being operated by the corporation has been steadily falling over the years under the Delhi government's policy of a 50:50 ratio of DTC buses and cluster buses on every route.
DTC also provides various other provisions like night services, tourist services, and airport express services. It also provides buses to Delhi Police and used to do so for some schools (however, this was stopped in July 2022).
Inter-state bus services
Until 2010, the Delhi Transport Corporation (DTC) operated interstate bus services to cities in North India. These services were discontinued after the fleet transitioned to CNG, a fuel that was not widely available in other states at the time. As of 2023, the Delhi government plans to relaunch interstate services with a fleet of 1,600 premium buses connecting major cities like Dehradun, Jaipur, Shimla, Chandigarh, Amritsar, Jammu, and Agra with Delhi. Under this plan, DTC will manage the services in collaboration with selected private operators. The fleet will include 1,200 electric buses designed for routes up to 200 kilometers (120 miles) and 400 BS-VI CNG buses for longer distances.
Fleet
As of March 2025, DTC has a fleet of 4,359 buses, with 3,109 CNG buses and 1,250 electric buses. This makes its fleet the largest CNG bus fleet in the world, and the largest electric bus fleet in India. The buses are dispatched from 37 bus depots across Delhi. With Delhi's total bus fleet numbering 7,135, 57% of these are operated by the DTC.

DTC has witnessed two major fleet improvements in its history. The first significant overhaul to its fleet happened in anticipation of the 2010 Commonwealth Games, when DTC received 3,125 new CNG low-floor buses (2500 first, followed by 625), which increased its fleet size to a high of 6,204 buses. This marked the first time DTC acquired low-floor buses, and since then, all subsequent orders have exclusively been for this type of bus. The new buses consisted of air-conditioned and non-air-conditioned Tata-Marcopolo low-floor Starbuses and Ashok Leyland ultra-low-floor (ULF) buses. The air-conditioned buses were painted red, while the non-air-conditioned ones were painted green, making them easily distinguishable. These new buses had features such as automatic transmission, power steering, ramps for disabled people, and stop-request buttons located on grab bars. With the introduction of these buses, Delhi's fleet of 2,400 privately owned "killer" Blueline buses was gradually phased out. In 2011, DTC planned to make use of biogas generated from sewage treatment plants to run its buses.
The second major upgrade to DTC's fleet began in 2021 when the Delhi government decided to exclusively procure electric buses going forward. Subsequently, with deliveries in multiple batches, DTC's fleet of electric buses has grown to 1,752, making it the largest e-bus fleet in India. The new buses feature digital ticketing, GPS, CCTV, and panic buttons, all connected to a two-way centralised command and control center at Kashmere Gate. The Delhi transport department plans to deploy 2,080 more electric buses in Delhi in 2025.
