This morning, the Bangalore Metro Rail Corporation Ltd. (BMRCL) commenced trial runs/testing on the Green Line’s 4 km underground section between Mantri Square (Sampige Road) and National College Stations. The train was operated by a 3 member crew at 10 km per hour with a primary aim to look out for any flaws in the track-system and third-rail system from which Bangalore’s trains draw power. In the coming weeks, the BMRCL and its various subcontractors’ engineers will operate and monitor the train’s response to higher speeds, and check its braking & track system performance as well as the interconnection with the Operations Control Centre (OCC).
The underground section with 3 stations is officially referred to as UG-1, and was built by the Coastal-TTS JV (tunnels & 2 stations) and Coastal-GYT JV (Majestic Station). The final TBM breakthrough to build the line’s tunnels was achieved by TBM Krishna at Majestic Station’s South Shaft in September 2016. Between March 13-22 2017, the BMRCL closed down a section of the Green Line between Sampige Road and Rajajinagar stations to configure & integrate the line’s traction, signalling and telecommunication systems. Following that, the underground section’s 3rd Rail system was charged up on March 28.
Here’s a video I shared on Twitter earlier today of a train rolling into the Majestic Station’s lowest level which houses the Green Line’s platforms:

With this development, the entire 12 km pending section of the 42.30 km Phase-1 project, between Sampige Road and Yelachenahalli, is now being tested. This figure includes the 8 km elevated Reach 4 & 4A, between National College & Yelachenahalli stations, on which the BMRCL commenced testing in November 2016.
The BMRCL held a media event at 4 pm to have the city’s Development Minister “officially” flag off testing from the KR Market Station. As per initial information coming in, one train left towards Chickpet Station while another left towards Majestic Station. Here are some images from the event:
More images and information on the testing schedule & subsequent opening will be added here later, so do check back.
Update: As per The Hindu, this is what the BMRCL has for public consumption:
BMRCL states that Low Speed Dynamic Tests will be conducted by April 14, multiple train tests and anti-collision tests by April 20 before going to the CMRS in the ‘last week of April’. BMRCL Managing Director Pradeep Singh Kharola sought to allay fears about completion of Chikpete station. According to BMRCL’s March newsletter, around 8% of the work on the roof remains. “We will complete this within 10 days,” he said.
BMRCL’s MD isn’t the most reliable or frank person out there, so the above dates should be taken lightly. Meanwhile, take a look at some images of Chickpet Station’s site which is far from becoming usable:
