Bangalore Metro Rail Corporation Ltd. (BMRCL) this week invited bids for civil construction work to extend Bangalore Metro’s 42.17 km Purple Line further north of the newly opened Whitefield (Kadugodi) Station.
This 588 meter long extension of the 73.92 km Bangalore Metro Phase 2 project‘s Reach 1B will take the Purple Line across the Indian Railways’ Bengaluru-Chennai line and up to Belatur Colony on Whitefield-Hoskote Road.
It will have no new stations, and its intended purpose is purely to improve train operations by adding a train reversal crossover-track facility.
Estimated Value: Rs. 42.30 crore
Contract Period: 18 months
Pre-Bid Meeting: October 20, 2023
Bid Submission Deadline: November 16, 2023 at 3 pm
Technical Bid Opening: November 16, 2023 at 3:30 pm
Brief Scope: Extension of metro line by length of 588 m (Approx.) beyond Whitefield Metro Station in Reach-1B and extension of 3rd line at Whitefield Depot by length of 28 m (Approx.) for Bangalore Metro Rail Project, Phase-2.
Tender: BMRCL/Phase-2/Reach-1B Extn./Via /2023/99
To give a little background, trains at Whitefield (Kadugodi) currently only use 1 platform to serve passengers. As the line literally ends 14 meters north of the station (view satellite imagery) inbound trains are forced to arrive at a restricted slower speed.
This new extension with a train reversal cross-over track facility will greatly improve train throughput and allow BMRCL to run high frequency train operations in the future. By using both platforms, a positive side effect is improved crowd management.
There’s one possible reason I can think of why this never got featured in Reach 1B’s original plan. Its extension involves crossing the Indian Railways’ line and dealing with its bureaucracy to secure design approvals and mega blocks.
The juice here was just not worth the squeeze compared to other challenging sections such as at Benniganahalli or Doddanekundi where the South Western Railways has sought a design change to increase the length of 65m open web girder to 85m.
