The Bangalore Metro Rail Corporation is set to begin trial runs this month on the 19.75-km Silk Board Junction-to-KR Puram stretch of Namma Metro Phase 2A, part of the Blue Line, according to Deccan Herald's reporting. Bengaluru Development Minister Krishna Byre Gowda had said back in June that testing would proceed in two segments: first from KR Puram to Marathahalli, then from Marathahalli to HSR Layout. The catch, as Deccan Herald's own sourcing makes clear, is that two of the stations on this line, Marathahalli and Silk Board, are not yet finished, so trains will likely run through those sections without stopping for some time.
1. Why Two Stations Are Still Incomplete
Marathahalli's composite girders have been installed, but finishing work at the station continues. Silk Board is the more complicated case: work at its dead end is ongoing, and the station is meant to eventually connect to the already-operational Yellow Line station nearby via an elevated walkway or travelator. Compounding this, the separate road flyover and ramps at Silk Board Junction, one of Bengaluru's most congested intersections, remain behind schedule, which several reports flag as a risk to the metro line's overall completion timeline as well.
2. When Will This Actually Open for Commuters?
Trial runs are not the same as commercial operations. While October 2026 marks the start of testing on this stretch, Goodreturns' coverage of the Blue Line's progress says the full commercial launch of Phase 2A has slipped to around March 2027, having originally been targeted for December 2026. For anyone budgeting a purchase decision around "the metro arriving," the realistic planning horizon is still several months out, and even then, Marathahalli and Silk Board stations may continue to be served later than the rest of the line.
3. What It Means for Buyers Along This Corridor
The Silk Board-KR Puram stretch runs through some of Bengaluru's most established Outer Ring Road micro-markets: KR Puram, Marathahalli, Sarjapur Road and HSR Layout, all of which have long drawn renters and buyers employed in the IT corridors that line the ORR. A metro connection here, even a delayed one, is a meaningful long-term infrastructure signal for these neighbourhoods, in the same way we've covered the Manyata Tech Park effect on Hennur rental yields on the other side of the city. KR Puram itself sits at the edge of the Old Madras Road corridor, which we've separately compared against Whitefield in our locality guide; better connectivity at that end is a relevant, if gradual, data point for buyers weighing that belt, including pre-launch options like Sattva Group's own Sattva Aangane further along Old Madras Road.
The Bottom Line
Phase 2A's trial runs are a genuine milestone, but not a finish line. Two stations on this stretch are still under construction, and the realistic commercial launch window has moved to around March 2027. Buyers evaluating ORR-adjacent neighbourhoods should treat this as confirmation that the corridor's long-term connectivity story is progressing, not as a reason to expect an imminent change in commute times.
