The Red Line's aging fleet of trains is struggling to cope with the cold and the snow, leading to reduced service and grueling delays this week on the MBTA's busiest subway line. On Tuesday morning, the MBTA issued an alert to Red Line riders to expect delays of up to 30 minutes after "multiple disabled trains were removed from service." Riders pack the platform of a Red Line station during rush hour on Wed. January 28, 2026. The Red Line already has the oldest trains in the MBTA's rapid transit network. As of today, though, the T only has 6 of those new CRRC Red Line trains (with 36 cars) in service.
