JR West developed Kiha127 series diesel railcars to run on upgrade Kishin
line linking Himeji and Niimi. The standard formation of kiha127 series
is 2-car formation by -0 sub-class vehicle with the toilet and -1000 sub-class
vehicle without toilet. Twin cab vehicles are classified into kiha122.
Their body construction is that the pressed stainless sheet and the outside
sheet are combined and those sheets themselves keep the strength, such
as 223-2000 series suburban electric trains. Their bodies are made stronger
than Kiha126 series. Their body design is similar to 223-2000 series DC
suburban electric multiple unit (EMU) trains. Two double slide doors are
located at the both ends of the body. Kiha127 series differ from kiha126
series in having no footstep.
Lightweight bolster-less bogies, WDT65/WTR259, are adopted. Vehicles are
equipped with a motored bogie and a trailer bogie. The brake system is
the electric command brake, such as kiha126 series. Kiha127 series are
equipped with a traction engine, SA6D140HE-2, adopting Common rail direct
fuel injection for anti-air pollution, a vehicle and are equipped with
hydraulic transmission gears, DW21 in order to achieve high service speed
and high acceleration performance. Since the generators for auxiliary power
is driven by the traction engines, and can supply 440VAC such as electric
trains, electric system is same as EMU trains.
Passenger accommodation is 2+1 abreast switchable transverse seating such
as 223-0 series. 2 air conditioners, WAU707 rated at 20,000kcal/h, are
fitted on the roof.
