What to know about the new MBTA fare pilot program now in effect

Two MBTA fare pilot programs started Tuesday.

For six months beginning Sept. 1, riders can make unlimited transfers within two hours and pay a lower express bus fare, according to the MBTA.

Riders can now make “unlimited” transfers between bus, subway, and ferry routes within a two-hour window, the MBTA website said. Riders must use the same payment method for all transfers and will only be charged for the highest-priced service.

Previously, riders could only make two transfers within two hours and could only receive a free transfer if they were switching between modes or between different numbered bus routes.

“For example, a rider could take a bus to the subway, run errands and return home within two hours while paying just one subway fare instead of multiple fares throughout the trip. The pilot is designed to reduce complexity and make it easier for riders to travel throughout the MBTA system,” the T said previously.

Additionally, the MBTA lowered the fare of an express bus from $4.25 to the local bus fare price of $1.70. Express buses connect the suburbs and communities outside of Boston with train stations and bus stops in the city, according to the MBTA.

The express bus program will save a daily express rider up to $500 during the six-month pilot period, according to the MBTA.

The change to the express bus fare does not apply to the Silver Line.

This fall, seniors over the age of 75 who do not have a driver’s license will be able to travel across all MBTA modes for free. Eligible seniors must apply for the program online when it becomes available this fall.

The start date for the senior program has not yet been announced, but the T said it will be in the fall of 2026.

“This pilot is in partnership with the Registry of Motor Vehicles (RMV) and aims to give our older generation more dignity, autonomy, and travel options,” the transit agency said.
