4.2 Introduction of pendulum-type diesel rail car (New Sprinter)
4.2.1 Speedup in narrow-gauge railway
Table 4.2-1 shows narrow-gauge railways of main countries. In the case of the maximum
speed in commercial operation, South Africa has the highest value of 160 km/h, then Japan
has that of 130 km/h (partly 140 km/h), and Thailand and Taiwan have that of 120 km/h. It
is needless to say that the narrow-gauge railway is inferior to standard- and broad-gauge
railroad in high speed traveling.
However, the national railway of South Africa achieved a high speed of 245 km/h in
1978, which was equal to the speed of standard- and broad-gauge railroad at that time
though it was the record of test traveling. Moreover, the motive power performance of a
car is greatly improved because of the recent advancement of car technology. Therefore, it
is estimated that even the narrow-gauge railway realizes a speed much higher than the
present speed.
