The Keha-class rail buses (Japanese ケ ハ, Korean 게하) were gasoline- powered 3rd class rail buses of the Chosen Government Railway ( Sentetsu ). There were five different types of this class made in Japan and Korea .
history
The first petrol rail buses in Korea belonged to the narrow-gauge Naheka class as well as the standard-gauge Keha 1 and Keha 2 classes, which were commissioned in 1930.
The Keha1 class of Maruyama Sharyō and the Keha2 class of Nippon Sharyō were delivered to Sentetsu in 1930. These somewhat streamlined rail buses were powered by a 107 HP (80 kW ) six-cylinder underfloor engine of the type 6Rof. Due to their lightweight construction, they weighed 25 t. They were 20 m long and had a top speed of 70 km / h. They had seats for 100 passengers. The interior design was rated positively by travelers. They were so successful that more were ordered.
After the success with the first six gasoline-powered rail buses, Sentetsu put 21 more into service over the next two years. The Gyeongseong Works supplied eleven with the numbers 15 to 25 in 1931 and ten more with the numbers 26 to 35 in 1931. These also had a Waukesha 6RB engine and 100 seats, but they were a little shorter than the first six rail buses. The radiators in the passenger compartment were heated by hot water pipes from a boiler in the goods compartment. The rail buses were equipped with both air brakes and hand brakes. The compressor had a V-ribbed belt . There was a driver's cab at both ends of the rail buses. The remaining rail buses were renumbered at a later date with numbers in the range from 70 to 79.
In 1934, a single rail bus manufactured by Nippon Sharyō was put into operation in Korea, which looked very similar to the JNR -Kiha07 class. The Gyeongseong Works built a single rail bus with the number 1 for their own use in 1936. This rail bus could carry 20 passengers and had a conference room with a table. Mechanically, these rail buses were almost identical to the other rail buses, but they were 4 m shorter.
Nippon Sharyō delivered five rail buses for 100 passengers each in a new design. They were powered by a 170 hp Kawasaki KP170B 6-cylinder engine and were intended for use on mountain routes. In 1942, an unknown number of probably seven rail buses in another design variant was finally delivered by Nippon Sharyō.
All these rail buses each had only one drive axle ( wheel arrangement 1A-A1). The rail buses from 1930 had a 12V alternator , the later ones had a 24 V generator of the type L3, 24V, 900W standardized by Sentetsu , which was driven via one of the axles .

After Korea's liberation from Japanese rule, 31 of the 60 rail buses with different drive variants ( Shiki class steam railcars, Jiha class diesel rail buses and narrow and standard-gauge petrol rail buses) remained in South Korea and the remaining 29 in North Korea. The South Koreans were eventually operated by the Korean National Railroad . Around 1954, the Korean National Railroad gave the standard-gauge rail buses new numbers in the 100 series. The petrol rail buses were taken out of service and scrapped between 1957 and 1963. They have been replaced by the DC class Korail Commuter Diesel Hydraulic Car.
