Trying to figure out how to get to Gillette Stadium for Taylor Swift’s highly anticipated Eras Tour? The MBTA this week will be adding tickets for the special event train service to the Foxboro concerts.

On Friday, the MBTA Commuter Rail and Keolis are releasing additional tickets for the May 20 and 21 round-trip train service to the Swift concerts at Gillette Stadium.

The MBTA is releasing more tickets “to meet the high demand for this service” as excited Swifties descend upon Gillette for the sold-out shows. Swift is returning to Gillette for the first time since her 2018 Reputation Stadium Tour.

The Boston special event trains will depart from South Station with stops at Back Bay and Dedham Corporate Center before arriving at the final destination of Foxboro Station.

The Providence special event trains will depart from Providence Station with stops at Pawtucket/Central Falls, Attleboro and Mansfield before arriving at Foxboro Station.

Trains will depart Foxboro Station 30 minutes after each concert ends.

The $20 round-trip tickets will be sold exclusively on the mTicket app, and will go on sale Friday at 11 a.m.

Tickets will be released for the May 20 and 21 special event trains from Boston and Providence. No additional tickets will be released for the May 19 special event train from Boston.

Due to high demand, no refunds or exchanges will be available. Tickets must be purchased prior to boarding the event train.
