The Golden Line (Line 10 and Line 11) is a rapid transit line of the Delhi Metro currently under construction in South Delhi. It will commence from Delhi Aerocity and terminate at Tughlakabad. Further extensions to Kalindi Kunj and Terminal 1-IGI Airport have also been approved as part of Phase 5A extension, and the works are currently underway. The main line (Line 10) will be long with 19 stations, comprising 7 elevated and 12 underground stations. The branch line (Line 11) will be long with eight stations, all of which will be elevated.
It will connect southern Delhi directly with Indira Gandhi International Airport to relieve the increasing traffic congestion and pollution prevalent on the streets of Delhi. Construction of the line began in June 2022 as part of the fourth phase of the Delhi Metro's development, and partial operations are expected to start by the end of 2026.
History The Golden Line, initially named as Silver Line, was conceptualised 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 spanning a length of about were planned to be added to the metro network, out of which the Golden Line would cover southern Delhi at a length of . The plans were finalised for implementation by the Government of Delhi in December 2018; per the implementation plan, the length of the Golden Line increased to . In March 2019, whereafter they were approved by the Government of India. Thereafter, land acquisition for Phase IV and the Golden Line began from April 2019, and was completed in three years. Construction was supposed to begin from 2021, but was delayed due to the restrictions imposed by the government on account of the onset of the COVID-19 pandemic. In June 2022, Afcons Infrastructure and Larsen & Toubro initiated the construction. It was expected to be completed by 2024/25, which was eventually pushed to the end of 2026.
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. 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 composed and outlined a Detailed Project Report (DPR) in December 2023, thereby increasing the line's length to . The name of the line was changed from Silver to Golden in January 2024.
The operational Sarita Vihar Depot serving the Violet Line is being modified to handle trains for the Golden Line too. Trainsets began started arriving at the depot from April 2026.
