A Twin Coach Model 23-S bus in service with the Kahului Railroad Co. in 1936. It is pulling out of the main bus stop in Wailuku with students headed for schools on the Paia route.
Three buses first entered service in August 1935 and five more were added in Mid-December 1935. By the end of 1936 the fleet totaled 16.
The bus was 25' 6" (777.3 cm) long, 6' 4" (193 cm) wide, 8' 7" (261.6 cm) high and weighed 4 tons (17,600 kg) empty. It was powered by a front-mounted Hercules JXDLT engine rated at about 80 horsepower. A governor limited the speed to 33 m.p.h for safety. The bus seated 28 passengers who entered and exited through a doorway located behind the front wheel. An emergency exit was located on the driver's side behind the rear wheels.
