It is out with the old and in with the new on the MBTA Blue Line.
As of September, the Blue Line has been all new six-car trains, all of the time.
The first of 94 new Blue Line cars began operating last year, replacing over time the old four-car trains.
The old trains and Maverick Station under construction are seen in the top photo at left, with the new Maverick and new cars attracting passengers in the bottom photo.
The new six-car trains are safer, more reliable, and bring increased capacity.
The old cars have been retired except for 20 maintained as backups, otherwise to be seen again only in the annals of the T.
