An airport train, built to connect Oslo, Norway, with the new Gardermoen International Airport 48 km (30 mi) away, is described as the world's quietest heavy railcar. At its design speed of 200 km/h (124 mph), the noise level it generates is substantially below that of conventional intercity trains although it operates at a higher speed. Measured at a distance of 25 m (82 ft) from the track, the train clocked in at a noise level of 88 dBA, compared with up to 95 dBA for a normal train operating on the same track at 130 km/h (80 mph). A reduction of 8 decibels means that the perceived noise is cut in half.
