Kiha110-0 is a single-car diesel multiple unit (DMU) train type developed
by JR East in order to replace obsoleted Kiha58 series vehicles used on
the express services of the Kamaishi and Yamada Lines. JR East delivered
3 pre-production vehicles in 1990.
They feature lighter and more powerful than the former DMU trains. Their
body constructed by the steel is 20,000mm long and 2,800mm wide. The floor
level becomes lower than the former DMU trains so the difference between
the step of the doorway and the floor becomes smaller. Passengers can open
or close plug doors manually by pushing buttons. They employed pipe-style
front-end skirts, and the tight lock coupler with the automatic jumper
coupler.
Lightweight bolster-less bogies, DT58/TR242, are adopted. Motored bogies,
DT58, adopt 2-axle drive. Their wheel base is 2,100mm long. The brake system
is the electric command brake.
Kiha110-0 vehicles are equipped with a prime mover, DMF13HZA or DMF14HZA,
rated at 420PS and are equipped with hydraulic transmission gears, T221rz
of Voith featuring the filling and emptying of the hydrodynamic circuit
in order to achieve high service speed and high acceleration performance.
All seats are adjustable reclining. Their seat pitch is 940mm. A Japanese
style toilet if fitted. The air conditioner is AU26J-A driven by the prime
mover.
Two production series cars, KiHa110-4 and 5 were subsequently delivered
in 1991. Both cars are equipped with Niigata DMF13HZA engines, and use
DT58A motored bogies and TR242 trailer bogies. Hydraulic transmission gears
were changed into multi-plate wet clutch hydraulic transmission gears,
DW14A-B.
Two-car diesel multiple unit (DMU) train, Kiha111/112-0 were also delivered.
All seats are adjustable reclining. Their seat pitch is 940mm. Kiha111-0
vehicles are equipped with a Japanese style toilet. The air conditioner
is AU26J-A driven by the traction engine.
Hydraulic transmission gears, T221rz of Voith, sued for pre-production
vehicles were changed into DW14A-B. The prominent anti-fall plates on the
front ends were began to be fitted later.
