In 1990, TSE (Trans Shikoku Experimental) 2000 series are diesel multiple
unit (DMU) train pre-production type developed by JR Shikoku for speeding
up at the curve and the gradient. TSE 2000 series feature the pendulum
body tilting mechanism in order to speed up at the curve for the first
time among the DMU trains in the world.
They feature the lightweight stainless-steel body. Reducing the wheel diameter
realizes the lower centre of gravity and footstep-less side doors. There
are two types of end cars. Type 2000 vehicles have a streamlined cab end
and type 2100 vehicles have a gangwayed cab end covered with horizontal
slideable plug doors.
Bogies are S-DT56, which was developed based on DT51 tried by 381 series, with built-in roller devices for body tilting system, and equipped with yaw dampers to ensure smooth ride characteristics even at high speed. The brake system is the electric command brake, incorporating the exhaust braking and compression release engine braking.
TSE 2000 series are equipped with 2 traction engines, SA6D125-H, a vehicle
and hydraulic transmission gears, TACN-22-1601, giving a maximum service
speed of 120ksm/h and high acceleration performance. The air conditioner
is AU26 driven by the traction engine.
All seats are adjustable reclining. They are 2+2 abreast seating and seat
pitch is 980mm. Type 2100 also provides sofa area. Video monitors, which
displaies vehicle front image and plays karaoke, are fitted in passenger
rooms.
TSE 2000 series vehciles were modified to mass production standard after introducing mass production type of 2000 series. Video monotors were rtemoved. Sofa area of type 2100 vehicle is alse removed and standard recling seatings are fitted. Front plug doors were removed and a new cover was fitted.
Although TSE 2000 series had been used on "Uwakai" intercity
services linking Takamatsu and Uwajima with mass production type of 2000
series, they were withdrawn by displacement with 8600 series in 2018. |
