 These cars were the first cars to feature a single flip-dot sign above a window next to the center doors, instead of two rollsigns found in the 1000 series cars.In place of the second rollsign, these cars are also the first cars to feature an exterior loudspeaker, as the 1000 Series cars lacked on loudspeakers, until it was rehabbed in 1993.The bulkhead on these cars were slightly higher than the 1000 series cars, and also have the flip-dot destination signs.
