an electric tilt train in queensland, australia. unlike other states in australia use different gauges, queensland s network made of 3 ft 6 in (1,067 mm) gauge track


the heavy duty 3 ft 6 in (1,067 mm) narrow-gauge railways in australia (e.g. queensland), south africa, , new zealand show if track built heavy-duty standard, performance standard gauge line possible. 200-car trains operate on sishen-saldanha railway in south africa, , high-speed tilt trains run in queensland. example of heavy-duty narrow-gauge line efvm in brazil. 1,000 mm (3 ft 3 ⁄8 in) gauge, has over-100-pound rail (100 lb/yd or 49.6 kg/m) , loading gauge large nonexcess-height lines. has multiple 4,000 hp (3,000 kw) locomotives , 200+ car trains. in south africa , new zealand, loading gauge similar restricted british loading gauge, , in new zealand british rail mark 2 carriages have been rebuilt new bogies use tranz scenic (wellington-palmerston north service), tranz metro (wellington-masterton service), , transdev auckland (auckland suburban services).


fastest trains

the reduced stability of narrow gauge means trains cannot run @ same high speeds on broader gauges. instance, if curve standard gauge rail can allow speed 145 km/h (90 mph), same curve narrow-gauge rail can allow speed 130 km/h (81 mph).


in japan , queensland, recent permanent way improvements have allowed trains on 3 ft 6 in (1,067 mm) gauge tracks run @ 160 km/h (99 mph) , faster. queensland rail s electric tilt train fastest train in australia , fastest 3 ft 6 in (1,067 mm) gauge train in world, setting record @ 210 km/h (130 mph). current speed record 3 ft 6 in (1,067 mm) narrow-gauge rail 245 km/h (152 mph), set in south africa, 1978.


a special 2 ft (610 mm) gauge railcar built otavi mining , railway company design speed of 137 km/h.


curve radius important high speeds: narrow-gauge railways allow sharper curves, limits speed @ vehicle can safely proceed along track.
