17 March 2026 – Major public transit agencies across the globe are announcing expansions and grappling with operational challenges, from service improvements in the Pacific Northwest to record ridership in India and enduring technical quirks in California. The week’s news highlights a sector in flux, responding to growing demand and climate pressures.
King County Metro Launches Systemwide Overhaul
In one of the most significant service changes in recent years, King County Metro will expand bus service and launch systemwide all-door boarding starting Saturday, 28 March. The changes, announced last week, aim to make transit faster and more accessible across the Seattle region. The expansion includes earlier morning trips, later night service, and increased frequency on weekends, with a particular focus on south King County and the Eastside.
The rollout coincides with other strategic adjustments, including a new path for Route 8 to connect with the soon-to-open Judkins Park Station on the expanding 2 Line light rail. County Executive Girmay Zahilay has also proposed a further major expansion of bus service across South King County, which could begin rolling out as early as August if approved.
Minnesota Moves Towards Transit Consolidation
Meanwhile, in the Twin Cities, a legislative panel has approved a plan for a Metro Transit takeover of all bus and rail services in the metropolitan area. The bill, passed five days ago, would make the Metropolitan Council the exclusive comprehensive transit provider beginning 1 July 2027. This move aims to streamline operations and planning across the region’s complex network of services.
Global Metro Expansion Continues Apace
Beyond North America, metro networks are growing rapidly. In India, the Delhi Metro has reported a staggering 235.8 crore (2.358 billion) passenger journeys in 2025, cementing its status as the nation’s largest network. On the subcontinent’s west coast, officials in Pune announced the expansion of its metro network, with new routes set to open in May and July of this year, promising to revolutionise the city’s commute.
Public Insight: The Sweltering Subway
A new study, highlighted across public forums and news reports last week, has quantified a common commuter grievance: subway systems are becoming uncomfortably hot. Researchers from Northwestern University analysed over 85,000 social media posts and Google Maps reviews from 2008 to 2024, finding a direct correlation between above-ground temperatures and passenger complaints about below-ground heat.
“Subway systems act as heat reservoirs,” one report concluded, with the issue drawing attention from transit advocates and engineers alike. This comes as agencies like New York’s MTA celebrate operational milestones, with Metro-North and the Long Island Rail Road reporting on-time performance rates above 97%.
Legacy Systems and Future Plans
The push for modernisation contrasts with the reality of ageing infrastructure. A report revealed that San Francisco’s Muni Metro still relies on floppy disks for part of its train control system, a testament to the challenges of upgrading complex, legacy transit technology. Elsewhere, forward-looking plans are taking shape, such as Austin’s CapMetro approving its Transit Plan 2035 last November, focusing on bus upgrades and rail expansion.
Frequently Asked Questions
When does King County Metro’s new all-door boarding start?
The systemwide all-door boarding policy, along with expanded bus service, takes effect on Saturday, 28 March 2026.
What did the subway heat study find?
The study, analysing over a decade of commuter feedback, found that above-ground temperatures directly influence passenger complaints about uncomfortably high temperatures in underground metro systems, highlighting a growing climate resilience challenge for cities.
Which metro system recorded the highest ridership in India?
The Delhi Metro Rail Corporation (DMRC) remained India’s largest metro network, recording 235.8 crore passenger journeys in 2025.
