Nagoya Municipal Subway 3000 series

The Nagoya Municipal Subway 3000 series is a Japanese city commuter electric multiple unit operated by the Nagoya Municipal Transport Bureau from March 1977 to March 2023 on the Tsurumai Line.
==History==
The 3000 series sets are the first generation of trains on the Tsurumai Line. The trains were introduced to promote the use of air-conditioned trains on the line. From 1977 to 1984 a total of 92 sets were manufactured; the sets were initially formed in four-car sets before they were reformed as six-car sets from 1993 with various cab cars from other sets inserted into other sets and rebuilt as intermediate cars. Minor refurbishment works began in 2003 and 2004 to replace the lamps.
Scrapping and retirements of the sets began in 2012 with the introduction of the N3000 series sets. The last set, 3114, was retired on 17 March 2023, with no special events held to mark their withdrawal; after the retirement of the sets all trains on the Nagoya Municipal Subway will use variable frequency drives.
==Design==
The 3000 series cars use a flat design with circular headlights.
==Specifications==
Construction of the cars is of a stainless steel. The sets use armature chopper control systems which produce a buzzing noise.
