The long-awaited new cars for Orange Line trains are going into service this week, the MBTA announced Monday.
Six of the new cars will go into service at 6 a.m. Wednesday, MBTA General Manager Steve Poftak said.
He announced the news on the same day the transit agency revealed that the Orange Line would see weekend station closures in October and November as part of a major acceleration of repair work on three MBTA lines.

That plan will bring closures to one of the Orange, Green or Red Lines almost every weekend from September through the end of the year.
The fleet of 152 new Orange Line vehicles is part of a $1 billion revamp ordered for it and the Red Line.
The cars will be more spacious, with wider doors and LED lighting, more accessibility areas and new communications systems, according to the MBTA.
