Western railway elevated corridor

[3] According to Sharat Chandrayan, CPRO of WR, "The road-show was mainly to explain requirements for the project to prospective bidders and to understand their suggestions before bidding takes place".

[6] The SSA is the state's commitment to help Railways in land acquisition, shifting utility services on time and attaining more FSI to help developers generate funds.

WR demanded an FSI of five for 13 land parcels across the city, in order to optimise commercial development of its existing plots as major source of funds for the project.

[8] The Maharashtra government sought central funding for the Mumbai Elevated Rail Corridor Project, which is aimed to revolutionise suburban commuting in the city.

The ministry had withdrawn the documents after realizing that the dispute between the state government and the railways over the signing of the SSA was frightening off potential bidders.

Six infrastructure firms – Reliance, Larsen and Toubro, GMR, Gammon, ILFS and CAF Spain – had bought the earlier RFQ document at a cost of ₹1 million (US$16,000) each.

The study found that terminating the corridor at Bandra would result in 40% reduction in passenger volume, which would make the project financially unviable.

The Railways commissioned Rail India Technical and Economic Service (RITES), its engineering arm, to conduct a fresh study as instructed by the PMO.

According to a railway board official, the contract for the corridor will be awarded by May 2014, if the Maharashtra government agrees to sign the state support agreement (SSA), after the new report.

[12] Following the November meeting, WR commissioned RITES to conduct a study on passenger volume projections if the elevated corridor was allowed to operate only between Virar and Bandra.

The study found that terminating the corridor at Bandra would result in an estimated loss in ridership of 40%, which would make the project financially unviable.

Chairman of Railway Board Arunendra Kumar and the Chief Secretary of Maharashtra J. Saharia met on 14 June 2014 to discuss the future of the project.

Due to space constraints in South Mumbai, the southern section of the line was planned to be underground from Oval Maidan to Mahalaxmi.

However, the proposed Line 3 of the Mumbai Metro would pass through the same area, requiring the construction of a tunnel at greater depth for the WR corridor.

In March 2016, Mumbai Railway Vikas Corporation (MRVC) announced that it had sent the Maharashtra government a modified state support agreement (SSA) for an elevated corridor from Andheri to Virar.

[25] It will consist of a 63.27 km two-track elevated corridor running above the existing Western Line, occasionally going underground and at ground level.

[27] Railway officials announced on 29 September 2012 that a decision had been taken to alter the earlier alignment and go underground for an additional 8.5 km stretch between Bandra and Jogeshwari to avoid having to buy and remove over 100 buildings extant on the planned route.

According to Mahesh Kumar, general manager of WR, the realignment would save money because he estimates that land acquisition and rehabilitation along the stretch would cost over ₹20 billion (US$230 million).

Western Railway (WR) intends to fund the project by commercially developing 130,000 square metres of land in 8 locations, of which five plots are Mumbai Central, Bandra, Andheri, Mahalaxmi and Borivali.

This would mean that Western Railway has to acquire a large number of expensive Multi Storey properties between Jogeshwari and Bandra and Dadar to Churchgate to lay the Elevated Corridor.
