Keio 1000 series (1996)

The Keio 1000 series is a Japanese suburban commuter electric multiple unit operated by the Keio Corporation since January 1996 on the Inokashira Line.
==History==
The 1000 series sets were introduced as a new train for the Inokashira Line, replacing the 3000 series sets and increasing transportation capacity. From 1995 to 2010 a total of 145 cars were produced, with the sets entering service on 9 January 1996. Replacement of the 3000 series sets was complete by 2011.

The 1000 series cars feature a slightly curved front with bottom-mounted horizontal square casings; the sets feature unpainted stainless steel bodies but feature pastel colors on their cabs as opposed to the Keio corporate livery of pink and navy blue. A stripe running down the side of the cars is painted in the same colors as the cabs. Set 1729 is painted in a special rainbow livery; this livery was originally intended to be temporary but due to its popularity the livery has essentially been made permanent.
==Specifications==
Construction of the cars is of stainless steel. The sets are equipped with various types of variable frequency drive traction systems; these were the first Keio trains on the Inokashira Line to be equipped with variable frequency drives. Odd-numbered sets between 1701 and 1710 use Tōyō Denki Seizō GTO drives while even-numbered sets within the same batch use Hitachi 3-level IGBT drives; all even-numbered sets have since been refurbished to use Tōyō Denki Seizō IGBT drives instead. Sets 1711 to 1715 use Tōyō Denki Seizō IGBT drives while all remaining sets use Hitachi 2-level IGBT drives.
These are the first Keio sets to feature an electronic horn. Each batch of sets are manufactured slightly differently and feature different specifications.
