April 24 – Original Post:
A consortium of Siemens India Ltd. – Siemens AG today emerged as the lowest bidder for providing the communications-based train control (CBTC) signalling solution for Bangalore Metro’s 19.143 km Yellow Line (Line-3 / Reach 5) connecting RV Road – Silkboard – Electronic City – Bommansandra.
Tenders for this international competitive bidding (ICB) contract of the 73.95 km Phase 2 project were invited in October 2019. Here are the financial bid values, unverified at this time, submitted by all 3 bidders. BMRCL’s estimate is unknown.
|Siemens||30 million Euros|
|Hitachi (Ansaldo STS)||38.6 million Euros|
|Alstom||40 million Euros|
April 29 Update: Naveen Menezes on Twitter was able to get the exact bid amounts in INR from BMRCL
With CBTC signalling in place, BMRCL will be capable of operating its 15 CRRC Nanjing Puzhen trains on Bengaluru’s new Yellow Line with high frequencies and headways of 1.5 minutes (90 seconds) with unattended train operations (UTO) or driverless operations in the future, if desired.
Alstom’s U200 Distance-to-Go (DTG) signalling solution on Bengaluru’s Line-1 (Purple Line) and Line-2 (Green Line), built in Phase 1 and being extended in Phase 2, can support train services with a minimum headway of 2.5 minutes. Prior to the suspension of operations due to COVID-19, BMRCL was operating trains with a headway of 4 minutes during peak hours and 10 minutes during non-peak hours.
Here’s a nice video comparing the old Distance-to-Go signalling (Fixed Block) with CBTC signalling:

If no issues arise during financial evaluation, then Siemens will be issued a letter of award in the coming weeks and enter its 6th city in India. Prior to this, they’ve won signalling contracts for parts of Delhi & Kolkata’s metro systems and the entire Chennai Phase 1, Gurgaon RMRG Line-1 and Nagpur Phase 1 metro systems.
