Train tickets for the 2026 FIFA World Cup will cost $80 and go on sale Wednesday, according to an announcement from the MBTA Monday morning.

The tickets will cover roundtrip service between South Station and Foxborough. They will be sold exclusively on the agency’s mTicket app starting at 11 a.m. on April 8, and will be valid for the entire commuter rail network.

The price tag is four times larger than the cost of a regular Commuter Rail trip between the two stations. Local fans have already expressed frustration about mounting transportation costs for attending the tournament.

Gillette Stadium — temporarily renamed Boston Stadium for the event — will host seven World Cup matches in June and July. Fans will be able to purchase tickets for the first five matches starting Wednesday. Tickets for Round 32 and Quarter-Final matches will be sold closer to match dates.

The MBTA did not provide information on the exact number of tickets that will be available but has previously said it expects to carry some 20,000 passengers on each match day. The agency warned passengers in its announcement that “Boston Stadium Train tickets are limited” and urged fans to purchase tickets as early as possible.

The T said tickets should not be bought without a valid ticket for a match on the same day. In order to buy a ticket, the agency will require passengers to register with an email address that was already used to purchase their match ticket.

“The MBTA is proud to have the opportunity to enable football fans from near and far to travel the Commonwealth, and we are ready to deliver unprecedented transit services to the seven World Cup matches held at Boston Stadium Interim Secretary of Transportation for Massachusetts and MBTA General Manager Phil Eng said in a statement.

“Taking the Commuter Rail will be one of the easiest and most affordable ways to get to and from the Stadium.”
