113 series

The 113 series (113系) is a Japanese suburban electric multiple unit (EMU) train type introduced in 1963 by Japanese National Railways (JNR), currently operated by West Japan Railway Company (JR West) and Shikoku Railway Company (JR Shikoku), and formerly also operated by East Japan Railway Company (JR East) and Central Japan Railway Company (JR Central).

The design was derived from the earlier 111 series, and used newer MT54 motors with an output of 120 kW. They are used in the mild temperature areas of Japan, due to their brakes not being capable of handling cold weather. The 115 series were built to operate in colder areas.

Variants

113-0 series

These sets were the first of the 113 series, and were put to use on the Sobu and Yokosuka Lines. They had the same body structure as the 111 series, only the driver's cab had been extended. In 1970, AU73X, AU74X, AU75X type air conditioning was fitted experimentally to sets operated in the Kansai area. The test was successful, and hence was fitted into the majority of the cars. Production of the -0 series ceased in 1973, and most sets have now been withdrawn.
