The Metropolitan Transportation Authority is preparing to order 650 new compressed natural gas buses, replacing more than 10 percent of its fleet in a single procurement cycle aimed at improving reliability and reducing operating costs for a system that serves over one million daily riders.
Key Takeaways
- The MTA will release a request for proposals for 650 new 40-foot CNG buses, with manufacturer submissions due October 19, 2026.
- The order replaces 620 aging CNG buses already in the fleet, some of which are 21 years old and well past their expected service life.
- CNG buses will account for roughly 30 percent of standard bus purchases under the MTA’s 2025–29 Capital Plan.
- The capital plan also funds 500 zero-emission buses and charging infrastructure at depots in communities disproportionately affected by poor air quality.
- All natural gas used by the MTA’s CNG fleet is offset by renewable natural gas sourced from landfills and farms.
- Forty-one new buses have already entered service since July, replacing vehicles with an average age of 18 years.
A Fleet Modernization Built Around Reliability, Not Just Emissions
Governor Kathy Hochul announced the procurement on September 10, describing the order as the single largest purchase of new MTA buses in over a decade. The 650 buses will be 40-foot, low-floor models powered by compressed natural gas, a fuel the MTA has used for years and one that agency officials say is cheaper, quieter, and more mechanically reliable than diesel. MTA Chair and CEO Janno Lieber framed the decision in practical terms, noting that the electric bus industry has not yet matured enough to fill this volume of need at this speed.
The MTA committed nearly a decade ago to transitioning its full fleet of close to 6,000 buses to zero emissions by 2040. That goal remains on the books, but the path to reaching it has shifted. Electric bus performance across the fleet has been uneven, with range limitations, charging infrastructure gaps, and maintenance challenges slowing the rollout. The CNG procurement does not replace the electric commitment; the same capital plan includes funding for 500 zero-emission buses and depot charging systems. But the 650-bus order signals that the MTA is unwilling to let fleet age climb while waiting for electric technology to scale.
The Procurement Follows a Broader Push for Faster Bus Service
The order is a direct extension of the “Next Stop: Faster Buses, Better Service” initiative that the MTA launched in July alongside Governor Hochul and Mayor Zohran Kwame Mamdani. That plan identified fleet age and mechanical reliability as factors dragging down bus speeds citywide. Since July, 41 new buses have already entered service, replacing vehicles with an average age of 18 years. The oldest bus retired under the initiative was 21 years old.
For riders across the five boroughs, the reliability problem is not abstract. Chronic delays and inconsistent service have plagued the city’s bus network for years, with disabled New Yorkers, older adults, and parents with strollers disproportionately affected. Newer buses spend more time on the road and less time in the shop, which translates directly into more frequent and predictable service on routes where riders have few alternatives.
CNG as a Bridge Fuel: Cost Savings and Environmental Offsets
The MTA’s decision to invest heavily in CNG rather than wait for a larger electric order reflects a calculation about operating costs as much as emissions. Compressed natural gas is cheaper per mile than diesel, and the agency says CNG buses require less maintenance overall. The fuel also insulates the MTA from diesel price volatility, a factor that matters at the scale of a fleet serving more than one million riders every weekday.
On the environmental side, the MTA offsets 100 percent of its CNG fuel consumption through renewable natural gas. RNG is produced from methane captured at landfills, farms, and other organic sources, which reduces lifecycle greenhouse gas emissions compared to conventional natural gas. CNG buses are also quieter than their diesel counterparts, a meaningful difference for neighborhoods where bus routes run through residential streets at all hours.
The capital plan does prioritize zero-emission infrastructure in communities most affected by air pollution. Charging equipment installations will focus on depots serving those neighborhoods, ensuring that the electric portion of the fleet expansion targets the areas where clean-air benefits matter most.
A New Procurement Model Designed to Encourage Innovation
The RFP is part of the MTA’s new Rolling Stock Program, which restructures how the agency buys buses and rail cars. Rather than issuing rigid specifications, the program gives manufacturers flexibility to propose new designs and technologies within broader performance requirements. The MTA says the approach is intended to speed up delivery timelines, reduce costs, and encourage competition among manufacturers.
MTA Chief of Rolling Stock Jessie Lazarus described the 650-bus order as a deliberate use of scale, noting that large order sizes allow the authority to leverage its multibillion-dollar capital commitment to get better pricing and faster turnaround from manufacturers. Proposals from interested bus manufacturers are due by October 19, 2026.
FAQs
How Many Buses Is the MTA Ordering?
The MTA is seeking manufacturers to build 650 new compressed natural gas buses, replacing 620 aging CNG vehicles currently in the fleet. Once delivered, the new buses will represent more than 10 percent of the MTA’s total bus fleet.
Why Is the MTA Choosing CNG Over Electric Buses?
The agency says electric bus technology has not yet scaled enough to fill this volume of need reliably. CNG buses are being ordered as a bridge solution while the MTA continues investing separately in 500 zero-emission buses and depot charging infrastructure under the same capital plan.
When Will the New Buses Enter Service?
Manufacturer proposals are due October 19, 2026. The MTA has not announced a specific delivery timeline, but the procurement is funded through the 2025–29 Capital Plan, and deliveries are expected to begin within that window.
Will the New Buses Serve All Five Boroughs?
The MTA operates bus routes across all five boroughs. The 650 new CNG buses will replace aging vehicles system-wide, serving more than one million daily riders across the city’s 345 bus routes.
