The 3200 series (numbered 3201–3457) is a series of Chicago 'L' car built between 1992 and 1994 by Morrison-Knudsen. 257 cars were built. As of 2013, 255 of them remain in service. The bodyshells of these cars were built by Mafersa, of Brazil, as a subcontractor to Morrison-Knudsen.[1]
The 3200 series was the last series of five interoperable series of Chicago 'L' cars known as the High Performance Family, and the last cars ordered for the Chicago Transit Authority that use direct current motors. Subsequent train orders are using alternating current motors.
The original order for 256 was motivated primarily by the impending opening of the Orange Line, which would need new cars when it opened in October 1993.[2] The order was completed in 1994.[3] The 3200-series contains many innovations over the previous 2600-series. Computers control much of the cab functions and simplify operation for the motorman. Diagnostics are also easier to perform on this series than on previous series. In addition, fluted steel siding is included on these cars for the first time since the 2200-series, in order to reduce graffiti. The series also introduced openable hopper windows for use in case of air conditioner failure.[3]
Cars 3441-3456 were originally equipped with pantographs for use on the Yellow Line, which was powered by overhead lines until 2004. The pantographs on 3451-3456 were removed in the late 1990s when they were reassigned to supplement the Brown Line, while the rest lost their pantographs when the Yellow Line was converted to third rail power in 2004.[3]
Car 3457 was an additional car built specifically for the purpose of serving as a mate to the 2600-series car 3032, whose mate had been damaged. 3032 was subsequently renumbered 3458.[4]
The 3200-series cars are currently all assigned to the Orange and Brown Lines and make up those lines' entire fleets. At various points during their service life a small number were also assigned to the Yellow and Purple Lines.
