The 8600 series (8600系) is a tilting limited express electric multiple unit (EMU) train type operated by Shikoku Railway Company (JR Shikoku) in Shikoku, Japan, on Ishizuchi limited express services between Takamatsu and Matsuyama since June 2014, replacing ageing 2000 series diesel multiple unit trains.[1] A total of 17 vehicles were delivered by February 2018, replacing all diesel units on the route.[2]

Design

The trains are built by Kawasaki Heavy Industries to a "retro-future" concept, with black front ends intended to evoke images of a steam locomotive.[3] The exterior livery includes orange and green highlights evoking the satsuma oranges and olives for which the region is famous.[2] Each vehicle is built at a cost of approximately 250 million yen, financed partially by national infrastructure investment subsidies.[2] The trains will operate at a maximum speed of 130 kilometres per hour (81 mph) in service, although they have a maximum design capability of 140 km/h (87 mph).[3] Tilting capability enables the trains to negotiate curves with a radius of 600 metres (2,000 ft) or more at a speed 30 km/h (19 mph) higher than the limit for conventional non-tilting trains.[3]

Formations
