The Golden Line (Line 10 and Line 11) is a rapid transit line of the Delhi Metro currently under-construction. It will start from Delhi Aerocity and end in Tughlakabad.[2] Further extensions to Kalindi Kunj and Terminal 1-IGI Airport have also been approved as part of Phase 5A extension. The main line (Line 10) will be 29.785 km (18.508 mi) long with 19 stations, out of which seven will be elevated and 12 will be underground. The branch line (Line 11) will be 8.385 km (5.210 mi) long with eight stations, all the stations will be elevated.

It will connect southern Delhi directly with Indira Gandhi International Airport to relieve the increasing traffic, congestion and pollution on roads. Construction began on the line in June 2022, as part of the fourth phase of the Delhi Metro's development, and partial operations are expected by 2026-end.

History[edit | edit source]

The Golden Line, initially named as Silver Line, was conceptualized by the Delhi Metro Rail Corporation (DMRC) under the Phase IV of Delhi Metro's future expansion and development in July 2016. As per the plan, six new lines covering a length of about 104 km (65 mi) have been planned to be added to the metro network, out of which the Golden Line would cover southern Delhi at a length of 20.2 km (12.6 mi). The plans were finalized for implementation by the Government of Delhi in December 2018; this time the length of the Golden Line increased to 23.6 km (14.7 mi).[3] In March 2019, the plans were approved for construction by the Government of India. Thus, land acquisition for Phase IV and Golden Line began from April 2019, and was completed by three years. Construction was supposed to begin from 2021, but was delayed due to the restrictions imposed by the government due to the COVID-19 pandemic. Hence, construction was started by Afcons Infrastructure and Larsen & Toubro in June 2022.[4][5] It was expected to be completed by 2024/25, which has been pushed to 2026-end.

In November 2020, the DMRC changed the alignment of the Golden Line as per the instructions of the Archaeological Survey of India (ASI) to circumvent the Qutb Minar and the Mehrauli Archaeological Park, so to avoid any harm to these critical historical sites during construction and operation.[6] As per the initial plan, the line was proposed to be extended to Terminal 1 of Indira Gandhi International Airport, in order to provide commuters a faster and direct link to the airport's premises. The proposal was approved by the Government of Delhi after the DMRC created and showed a Detailed Project Report (DPR) in December 2023, thereby increasing the line's length to 25.82 km (16.04 mi).[7][8] The name of the line was changed from 'Silver Line' to 'Golden Line' in January 2024.[9][10]

The Sarita Vihar Depot serving the Violet Line is being modified to handle trains for the Golden Line also. Trainsets have started arriving at the depot as of April 2026.
