Line 10 (Mumbai Metro)-Cedar Herald Index

Green Line 10 (extension) of the Mumbai Metro, also referred to as the Gaimukh-Shivaji Chowk (Mira Road) corridor, is part of the metro system for the city of Mumbai, India. This line is fully elevated.

In February 2017, the MMRDA announced that the DMRC was preparing a detailed project report (DPR) on Metro 10. Preliminary plans prepared jointly by MMRDA and DMRC. The line will run parallel to Thane - Bhayandar Highway, and will joint with metro route no 9 at Chhatrapati Shivaji Maharaj Chowk. The project is estimated to cost ₹3,600 crore (US$530 million).

Line 10 (Mumbai Metro)

Prime Minister Narendra Modi in Mumbai on September 7 laid the foundation stone of Mumbai Metro Lines 10 the long Gaimukh to Shivaji Chowk (Mira Road) Metro-10.It is expected to be completed in 2030 and is expected to provide interconnectivity among Mira-Bhayander, Thane, Borivali and rest of Mumbai. It will reduce the current travel time by between 50% and 75% depending on road conditions.

Construction

The Government of Maharashtra is keen to implement expeditiously the Master Plan Corridors recommended by DMRC on a fast track mode and to complete them in the next 3–4 years. To start with, it is decided to take up the task of updation of DPRs and also preparation of new DPRs for the following potential elevated metro corridors

Line 10 (Mumbai Metro)

1. Gauge (Nominal)::- 1435 mm

2. Route Length::-

3. Number of stations::- 4 (All Elevated)

4. Traffic Projection: :-

Extension from Gaimukh to Shivaji Chowk (Mira Road)

5. i. Design Speed 90 km/h

ii. Maximum Operating Speed 80 km/h

iii. Schedule Speed 35 km/h

6. Traction Power Supply: :-

a. Traction system voltage 25 kV AC

b. Current Collection Over Head Catenary

c. Receiving Sub Stations One near Kashimira/ Shivaji Chowk

(Mira Road)

7. Maintenance facilities: :-

No additional depot has been proposed for this extension. Same depot of Gaimukh to CSMT metro corridor, either at Owale or Gaimukh shall be used for this extension also after due augmentation.

8. Structure: :-

i. Elevated: Viaduct with precast twin „U‟ girders on a single pier with pile foundations' radius up to and flatter, for sharper curves and location of points and crossings I-Girder. Station structure with viaduct columns supporting the concourse girders by a cantilever arm.

ii. Underground section with New Austrian Tunneling Method (NATM). For the small underground section running under the hills, New Austrian Tunneling Method (NATM) of underground construction can be employed.

9. Terminals :-

Since this is an extension of Gaimukh to CSMT metro corridor on Gaimukh end. Thus this section has only one terminal station as mentioned below:

Shivaji Chowk (Mira Road) This is an elevated station. It is proposed parallel to proposed Kashigaon Station of Metro Line-9. Scissors cross overs are proposed at the rear end of this station. Scissors Crossovers will be provided at the terminal station viz. Shivaji Chowk (Mira Road) station.

10 Depot :-

No additional depot has been proposed for this extension. Same depot of Gaimukh to CSMT metro corridor, either at Owale or Gaimukh shall be used for this extension also after due augmentation.

Planning

The proposed Metro Rail at Mumbai has one corridor covering an approximate distance of about . The corridor will have four stations, all elevated. Some sections of the corridor are underground/below the hill. Almost all the stations are on the road stations.

The stations have been located so as to serve passenger requirements and to enable convenient integration with other modes of transport. Efforts have been made to propose station locations at a uniform inter-station distance as feasible. The average inter-station distance is ≈2 km, though it varies from 0.873 km to 4.34 km due to land-use and topographic reasons. The minimum inter-station distance is between Shivaji Chowk (Mira Road) Station and Kashimira Metro Station i.e. 872.941 m. The maximum inter-station distance is between Gaimukh Reti Bundar and Varsova Char Phata i.e. 4342.345 m.

Station Type

The stations have been planned with side platforms to avoid the viaduct structure from flaring in and out at stations, which obstructs the road traffic below. Care has been taken to locate stations in straight alignment. However, in some stations, site constraints have become the deciding criteria and a curve of 1000m radius has been introduced in the platform.
