DMRC Publishes New Phase 4 Map & Table of Delhi’s Metro Project

So back in late-March, the Delhi Metro Rail Corporation (DMRC) published a notice inviting Express of Interest (EoI) bids from companies to appoint a consultant for conducting a hydro-geological study on the upcoming underground corridors of the 103.93 km Phase 4 project.

The basic scope of this key pre-construction activity is to identify the impact due to the:

de-watering on ground water due to the upcoming Phase-IV of Delhi MRTS network. The main elements of the study are to delineate the area of influence due to dewatering, to predict change in water level due to dewatering using ground water modeling and to develop a mitigation plan

Within that notice, is this brilliant detailed table of Phase 4’s lines which indicates their lengths (elevated, underground) as well as the number & characteristics of stations. The lengths of the corridors can be expected to change marginally by the time detailed designs are prepared and civil bids are invited, but this can be taken as a good benchmark:

Also included within the notice is this Phase 4 map which is said to have been updated in January 2017, around the time when the project got approved by the Delhi Government’s Cabinet.

This map was prepared on top of their map for Phase 3, and a higher resolution can be viewed here or within the notice.

The biggest take-aways, both excellent, include:

1. Confirmation that the Aerocity – Terminal 1 section of the Airport-Tughlakabad line has indeed been dropped.
2. Addition of a station at Saket D-block which will serve the Select Citywalk Mall – Saket District Court area that I’ve always desired.

Other observations:

1. In addition to the Kalindi Kunj Depot, the Magenta Line will have a new depot at Mangolpuri.
2. The new Aerocity – Tughlakabad line and its spur between Saket – Lajpat Nagar will be served by a depot at Rangpuri.
3. The map obviously doesn’t include the Najafgarh – Dhansa Bus Stand extension of Line-9 which got approved this week. Perhaps it will be in the next iteration.
4. This map only includes lines approved within Delhi’s borders. There are many proposals, some serious and some so not, elsewhere in the NCR (eg. Gurgaon, Faridabad & Ghaziabad) which are currently awaiting their respective state government’s approval.

Are there any other observations you’d like me to add? Just leave a comment below.

Phase 4’s Current Status

The project was approved by the Delhi Government’s Cabinet in January 2017 and has since then been waiting for the Central Government’s approval. There’s still no word or confirmation on its funding split and which external agency (is JICA still onboard?) is going to provide a loan to fund it. Meanwhile, behind the scenes, consultants are currently conducting various pre-construction surveys, such as geotechnical investigations, topographical surveys and soon a hydro-geological study. Data captured from these activities will help prepare detailed designs, cost-estimations, and will be included in the tender documents whenever the DMRC invites civil construction bids.

Recap:

• New Lines:
Tughlakabad – Aerocity (20.20) – shown in moss green below
