Чикаго, вагон метро № 3458

Ex 3032 -- Budd CTA 2600 series
There were only 256+1 cars of this type (Morrison-Knudsen 3200 series). An additional car was added to the order -- bringing the total to 257 cars -- which was paired with 2600-series car 3032, whose mate was damaged in an accident. Car 3032 was renumbered 3458 on February 25, 1994, and paired with car 3457, created the first "mis-mate" that consisted of two cars of different series.
