JR Shikoku 1000 series  The is a single-car diesel multiple unit (DMU) train type operated on local regional services by Shikoku Railway Company (JR Shikoku) in Japan since 1990. The 1000 series trains are used on the following JR Shikoku lines. A total of 56 1000 series cars were built by Niigata Transys between 1990 and 1997, delivered in four batches as shown below. Passenger accommodation consists of a mixture of longitudinal bench seating on one side and transverse seating bays on the opposite side. Toilets have been retro-fitted to a number of cars since February 2001. In 2008, 18 1000 series cars were modified to make them compatible with newly delivered 1500 series DMU cars, and were reclassified as 1200 series.
