This car controls the tilting angle of the car body before reaching transition curves, using data such as the distance to each curve calculated based on the location of the ATS wayside coil stored in the train computer, curve diameter and cant to control the strokes of the air compressing cylinder attached between the pendulum beam and the bogie frame. JR Shikoku's Series 2000 DC Special Express and the Series 8000 EC number among these cars. (Fig. 5.2 illustrates the principle in diagram form.)
Speed is improved along curves by 30 - 35%.
5.3.3 Others
The development of other cars, including:
* bearing guide cars;
* hydraulically sealed circuit cars; and
* link cars,
is being supported to make the tilting device more compact, reduce tilting resistance and other reasons. At present, most cars are of the bearing guide type. Examples include the JR East Series E35 1 Special Express Train and JR Hokkaido's Kiha Series 281 Special Express Diesel Car. (See Fig. 5.3.)
