During a detailed simulation test, the train speed on the remaining section of Phase II-B between KR Puram and Yelahanka will be just 36 km ph, the document stated.
The document added that trains on the
“In all, there are 88 curves and 36.44% of length falls in horizontal curves on the stretch,” as per details.
The entire 37-km network, estimated to cost Rs 10,584 crore, comprises of 17 stations — Kasturinagar, Horamavu, HRBR Layout, Kalyan Nagar, HBR Layout, Nagawara, Veeranna Palya, Kempapura, Hebbal, Kodigehalli, Jakkur Cross, Yelahanka, Bagalur Cross, Bettahalasuru, Trumpet Junction, KIA West and Airport Terminal.
Officials estimate the daily ridership to touch 4.32 lakh in 2031.
As per the document, the BMRCL will be using precast pretensioned U-girder superstructure, which will be transported to the site and erected on the spans using road cranes. There will be two girders for each span to cater for the two tracks: “Since these units are erected as a single unit per span, the speed of construction of superstructure becomes very fast compared to the segmental construction. Since the pier cap will have to accommodate two U girders, it has to be wider and hence is made as a precast prestressed unit.”
The stretch will also get the latest technology available in the signalling and train control system known as Communication Based Train Control (CBTC). While the BMRCL has already taken possession of the properties needed for the project, the utility is yet to finalise the contractor to execute civil works.
No Metro-cum-Road flyover
The BMRCL, which had initially planned to construct a Metro-cum-Road flyover between Mahadevapura and Ramamurthy Nagar, has dropped the plan, citing a lack of space. As per the revised plan, the BMRCL will be adding two new lanes near Benniganahalli Lake for traffic moving towards IT corridor or Hoskote from Jyothipuram. Namma Metro, which has already provided two new lanes near Tin Factory for the traffic moving from KR Puram, will get an additional lane. The work on adding three new lanes might begin in about a month’s time as the BMRCL is currently in the process of razing properties.
