Noida Metro Rail Corporation (NMRC)’s board on Monday approved the revised Detailed Project Report (DPR) for 29.7 km Noida Metro Aqua Line‘s Extension to Knowledge Park V in Greater Noida West, per Indian Express.

The revised DPR prepared by Delhi Metro Rail Corporation (DMRC) envisions a 17.43 km extension of the Aqua Line from Sector 51 Station to Knowledge Park V via 11 new stations. Along the way, a proper interchange facility is proposed to be built with the Delhi Metro’s Blue Line at Sector 61 Station.

11 stations are proposed to be built at Noida Sector 61, Noida Sector 70, Noida Sector 122, Noida Sector 123, Greater Noida Sector 4, EcoTech 12, Greater Noida Sector 2, Greater Noida Sector 3, Greater Noida Sector 10, Greater Noida Sector 12 and Greater Noida Knowledge Park V.

Here’s my take on how the line’s alignment and the location of its stations might end up looking:

Although not disclosed, I see this plan definitely involving part demolition or abandonment of the Aqua Line’s viaduct built north of Sector 51 Station (view on Google Maps). This additional viaduct with a buffer-stop was built by CEC – SAM India JV to allow the reversal of trains and position the line for its future extension.

In order to accomplish this re-route, the Aqua Line will have to cross the Blue Line twice – once at the intersection of Vishwakarma Marg – Vikas Marg and the other just south of Sector 61 Station.

Here’s a map showing both features:

The revised DPR has now been sent to Noida Authority for its approval. Following their feedback and approval, the DPR will subsequently be sent to the Uttar Pradesh government for its cabinet’s approval.

The project’s prior DPRs envisioned a 14.95 km eastern extension of the Aqua Line from Sector 51 to Knowledge Park V. A foot overbridge (FOB) was planned to connect Sector 51 (Aqua Line) and Sector 52 (Blue Line) stations. That plan was cancelled for a more tightly-integrated interchange facility.

GR Infraprojects was declared as the lowest bidder in December 2021 for this extension’s first civil package (Noida’s Sector-51 to Greater Noida’s Sector-2) after four rounds of bidding, but a contract was never awarded. It goes without saying, but NMRC will have to re-invite bids for the line’s construction for the fifth time when the project receives approval.
