The KiHa 285 series (キハ285系) was a tilting diesel multiple unit (DMU) train type developed by Hokkaido Railway Company (JR Hokkaido), originally intended for use on limited express services in Hokkaido, Japan. One three-car trainset was completed in September 2014 by Kawasaki Heavy Industries in Kobe, but plans to construct any further KiHa 285 series trains were cancelled the same month, and the trainset built was scrapped without entering revenue service.
The KiHa 285 series train uses a new compound tilting system, which tilts the train vehicles by up to 8 degrees using a pendular system (tilt of up to 6 degrees) combined with air suspension tilting (tilt of up to 2 degrees).[1] The train also uses a new motor-assisted ("MA") hybrid diesel traction system, which supplements conventional diesel traction with batteries, inverters, and electric motors.[1] The train was designed to allow a maximum speed of 140 km/h (87 mph) even on curves.[2] Total development costs for the train came to 2.5 billion yen.[3]
