BANGALORE (Metro rail News): Alstom Transport India has announced that the signalling & electrification work for  Bangalore Metro‘s 15.257 km Reach 1A & Reach 1B (Baiyyappanahalli – Whitefield) extension of the Purple Line has been completed.

Bengaluru Metro Rail Corporation Limited (BMRCL) can now undergo full-fledged dynamic train testing on the extension after the development, which is anticipated to open in the middle of 2023.

The 2.25 km Byappanhalli – Benniganahalli (Tin Factory) – KR Puram segment, where civil construction work is still in progress, is not included under the scope of this milestone.

The Whitefield extension is the longest expansion of the Phase 1 lines of Bangalore Metro’s 73.92 km Phase 2 project. All 24 track turnouts for it had been cast in September 2022 by Texmaco Rail and Engineering.

In October, BMRCL began simple test runs between the 3.5-kilometre Whitefield metro station and Pattandur Agrahara metro station. Since then, testing has been gradually extended to the western sections of the line with the primary objective of looking for Schedule of Dimension (SoD) clearances.

The 2.25 km Byappanhalli – Benniganahalli (Tin Factory) – KR Puram section of the line has undergone numerous design changes and has been hampered by difficulties with land acquisition.

The launch of a 65-meter Open Web Girder (OWG) above Indian Railways tracks at Benniganahalli, scheduled to take place on 23rd December, has been postponed.

A BMRCL representative told Christin Mathew Philip at TOI about the delay in installing many HSFG bolts and tightening them to design torque; due to this, OWG’s launch has been delayed by a few days.

BMRCL will begin operations between KR Puram and Whitefield only once end-to-end civil and track construction on the full extension is done. This is because the depot still needs extensive civil and systems installation work.
