Metrolink Express for Gandhinagar and Ahmedabad (MEGA) is a proposed mass-transit rail system for the cities of Ahmedabad and Gandhinagar, India.

The DMRC (Delhi Metro Rail Corporation Ltd) has already done its techno-feasibility study and submitted its report. Gujarat government has recently re-approached Delhi Metro Rail Corporation (DMRC) for a modified detailed project report (DRP) for a metro rail project in Ahmedabad.[3]

The state government has set up a Rs 200 crore company for the execution of the project. The company is named the Metro Link Express for Gandhinagar and Ahmedabad (MEGA).[4] The formation of MEGA is expected to give a major boost to both the metro rail project and the regional rail project which aims to connect the peripheral areas of Ahmedabad with the dedicated rail link.

Based on a long-term cost and benefits analysis conducted by consultants M/s Egis Rail of France, broad gauge was selected for this project.[5]

History[edit]

A metro rail system to facilitate movement between Gandhinagar-Ahmedabad was the outcome of the IPTS study for Ahmedabad initiated by Gujarat Infrastructure Development Board (GIDB) to identify the solutions for urban transport problem in the city. Preparation of detailed project report (DPR) for the metro system for Ahmedabad and Gandhinagar was initiated by GIDB in 2003 through Delhi Metro Rail Corporation (DMRC) and RITES. The DPR was submitted by DMRC in June 2005 and received Central Government approval the same year.[6]

As per the DPR, the total project cost was 4295 crore rupees, and the project revenues were estimated based on projected Fare Box revenue. In addition to Fare Box revenue, 10% of Fare Box revenue was estimated to be generated through value capture of property development. Based on above assumptions, the FIRR of the project was estimated to be 4.64%. It was assumed that about 1500 Crore rupees will be generated through property development, and another 1500 Crore would be infused by the Government as Viability Gap Funding. Later, it was decided not to go ahead with Metro Rail project to give priority to the BRTS and Regional Rail system Projects.

Considering the forthcoming developments in and around Ahmedabad – Gandhinagar, in 2008 it was decided to go ahead with the Metro Rail Project. It was also suggested to provide linkages of the Metro Rail System to GIFT City which is required to make it viable and to Sardar Vallabhbhai Patel International Airport.

In December 2009, the 32.65 km North-South Ahmedabad – Gandhinagar line was proposed to be shifted from Ashram Road to parallel regional rail network line of Western Railways operated by Indian Railways as there was no space on Ashram Road. Other reasons state government has declared Sabarmati Ashram as a silent zone and there is a lack of space for some of the major metro stations – Usmanpura and three stations planned between Paldi and RTO Circle.

In February 2010, the state government proposed that 10.9 km East-West metro line will be shifted from Income Tax – Shahpur Darwaza – Delhi Darwaza – Prem Darwaza – Kalupur Line towards Relief Road and wants it to be underground. Special Hydraulic platform with a small gradient that would gradually take a stationary metro train to the tunnel level on Relief Road – Kalupur stretch is also being proposed for this line.

In October 2010, Gujarat Infrastructure Development Board (GIDB) chief executive officer AK Sharma announced that work on the first phase of the Rs 1,100 crore Ahmedabad-Gandhinagar metro rail project would start the following year and the line was expected to be operational within two-three years. The metro line, in its second phase, would connect Ahmedabad with Dholera, the site of a special investment region. Details for the second phase were still to be worked out.

In January 2011 the Gujarat government decided to fast-track the Rs 12,000 crore metro rail project. Delhi Metro Rail Corporation (DMRC) submitted a project report on the alignment of metro network to the government. It recommended mostly an elevated route for the first phase of metro, with the stretch from Nehru bridge to Ahmedabad junction being underground.[7]

For the speedy execution of the metro project, the Gujarat government has already formed a special purpose vehicle—Metrolink Express for Gandhinagar and Ahmedabad (MEGA) – with authorised capital of Rs200 crore and initial paid-up capital of Rs10 crore.[citation needed] The government appointed businessman Sanjay Gupta to head the project (previously CEO of the Adani Group).[8]

The metro rail – meant for an estimated 17 lakh commuters daily —- would connect APMC Vasna to Akshardham via Ashram Road, Koba Circle (32.65 km) with 31 stations, and Thaltej to Ahmedabad junction via Sabarmati riverfront and Delhi Darwaja (10.90 km) with 11 stations, in the first phase.[7] The North-South metro route is to be connected to Mahatma Mandir. In recent state budget 2012–13 Gujarat Government allotted 500 crore rupees to MEGA.

On 14 August 2012, Union urban development minister, Kamal Nath, claimed in the Lok Sabha that he was yet to receive a DPR from the Gujarat government for the metro rail project. According to him, the Gujarat government had so far only taken an "in-principle" decision to adopt the framework of 50:50 joint ownership special purpose vehicle between the state and centre for the project[9] However, Minister of State for Urban Development, Sugata Roy, in a 2011 Lok Sabha session, had claimed that the Gujarat government had submitted a DPR prepared by DMRC. According to Roy, the Gujarat government had demanded central assistance to the extent of at least 25% of total project cost.[10]
