Nu este impresionant în mod deosebit prin soluţiile tehnice folosite sau prin lungimea traseelor ci prin cu totul altceva.
India e o ţară în care proiectele de infrastructură se realizează în zeci de ani şi cele mai multe mor din cauza birocraţiei şi a lipsei de bani. Metroul din Calcutta s-a construit cu întârzieri imense şi cu bugetul depăşit de 12 ori.
În New Delhi, nu doar că s-au încadrat în buget, ci au terminat magistrale cu 3 ani mai rapid decât termenul de execuţie asumat. Banii au venit din împrumuturi externe şi consultanţa a fost asigurată de MTR Hong Kong, unii dintre cei mai buni specialişti din domeniu.
Totul a fost posibil pentrucă au creat o organizaţie care a simplificat cu mult birocraţia, care a controlat fondurile, execuţia şi care a putut trece peste problemele birocratice şi autorizaţii cu uşurinţă. Organizaţie în fruntea căreia au pus cel mai bun tehnocrat din India, nu un politician sau un "băiat deştept".
Physical construction work on the Delhi Metro started on 1 October 1998. After the previous problems experienced by the Kolkata Metro, which was badly delayed and 12 times over budget due to "political meddling, technical problems and bureaucratic delays", DMRC is a special-purpose organisation vested with great autonomy and powers to execute this gigantic project involving many technical complexities, under a difficult urban environment and within a very limited time frame. DMRC was given full powers to hire people, decide on tenders and control funds. The DMRC then hired the Hong Kong MTRC as a technical consultant on rapid transit operation and construction techniques.
The first line of the Delhi Metro, the Red Line, was inaugurated by Atal Bihari Vajpayee, the Prime Minister of India, on 24 December 2002. The Delhi Metro became the second underground rapid transit system in India, after the Kolkata Metro, when the Vishwa Vidyalaya–Kashmere Gate section of the Yellow Line opened on 20 December 2004. The first phase of the project was eventually completed in 2006, on budget and almost three years ahead of schedule, an achievement described by Business Week as "nothing short of a miracle".
În 16 ani au construit 300 de kilometri de metrou, 8 linii şi mă tem că la un cost mult mai mic decât metroul bucureştean.
Timpul scurt de realizare şi costul scăzut a fost influenţat şi de faptul că nu tot parcursul este în subteran, o parte este la nivel sau suspendat.

Delhi Metro has introduced the driverless train operation on the 59 km long Pink Line from Majlis Park in the northern part of the city to Shiv Vihar terminal metro station in the North-East Delhi.
The official ceremony was attended by the Secretary of the Ministry of Housing and Urban Affairs (MoHUA) Durga Shanker Mishra and the Managing Director of DMRC, Mangu Singh, while the Minister of MoHUA Hardeep Singh Puri and the Transport Minister of NCT of Delhi, Kailash Gahlot, attended via videoconference.
Delhi Metro Rail Corporation (DMRC) says that initially the train operator will remain onboad to instil a sense of confidence and assistance. The technology’s higher level of diagnostic features will help move from conventional time-based maintenance to condition based maintenance. This will also reduce maintenance down time of trains.
The driverless train operation will bring more flexibility in train operations, reduce human interventions and human errors. It will also help in improving the availability of coaches for service. The driverless trains will remove the manual process of checking done before induction, subsequently reducing burden on train operators. The parking on stabling line in depots will also be done automatically.
The driverless technology was launched on the Magenta Line in 2020 with which the Delhi Metro had entered world’s 7 per cent driverless metro system. The DMRC has already started reaping benefits of driverless operations on the Magenta Line in terms of increased availability of coaches for service. Reliability of the trains have increased manifold due to exhaustive self-tests done before induction in service everyday automatically eliminating all possibilities of human error. The benefits will further increase with a longer network under driverless train operation.
With this project, the automated train operation on Delhi Metro system reaches 97 km, which is 4th largest in the world and the only driverless network in India. After the completion of Phase 4, when driverless operations will be available on the extensions of the Pink and Magenta Lines as well as on the Aerocity – Tughalakabad Silver Line, DMRC shall become the world’s second largest driverless metro network with 160 km of automated operation.
