Bombardier Transportation MR-73, introduced in 1976.
Once used in majority on the Orange Line, they were migrated to the Green Line as MR-63 were being retired.
They are now used exclusively on the Green Line, Blue Line and Yellow Line.

Bombardier-Alstom MPM-10, named "Azur" by the public in 2012, entered service in 2016.
The order completely replaced the outgoing MR-63 model.
They use an open gangway design that allows passengers to walk from one end of the train to the other.
