Sapporo Municipal Subway 3000 series

The Sapporo Municipal Subway 3000 series was a rubber-tired Japanese city commuter electric multiple unit operated by the Sapporo Municipal Transport Bureau from October 1978 to March 2012 on the Namboku Line.
==History==
The 3000 series sets were introduced in 1978 to increase the transportation capacity on the Namboku Line in preparation for an extension from Kita-Nijūyo-Jō to Asabu. The first set was introduced on 1 October 1978, initially classified as the eighth 2000 series set, but due to significant changes from the 2000 series in terms of appearance and equipment the train ultimately received a designation of its own. Four more trains were built from 1982 to 1990, making up the smallest roster of trains on the Namboku Line and the Sapporo Municipal Subway as a whole.
The first set, 3101, was retired in March 2003 and scrapped in 2005. The remaining four sets were then replaced by 5000 series sets from 2010 to 2012, with the last set retiring in March 2012. No 3000 series cars have been preserved.
==Design==
The 3000 series sets used a streamlined front end with side-mounted rectangular headlights.
==Specifications==
Construction was of steel. The trains used armature chopper-controlled traction systems which produce a buzzing noise.
