Three of the T's first new Orange Line cars arrived in Boston this week to begin testing and trial runs on an MBTA test track.

The cars, shot by photographer Brian Cummings of 781 Photography are at the MBTA's Wellington carhouse after traveling through the Panama Canal from Changchun, China, where they were manufactured by rail giant CRRC.

Six of the new cars have been made in China, with the balance in the order of 152 Orange Line and 252 Red Line cars to be built at CRRC's plant in Springfield. The new cars, which may begin seeing revenue service a year from now, are to replace aging trains, some dating back to 1969.
