Construction Sky Bus can run at 100 km/h using electric power[citation needed], with suspended coach shells that carry the passengers. Railway Heavy 52 kilograms per metre (100 lb/yd) rails of standard gauge are placed in 8m x 2m-box enclosures. These rails are supported over 1m diameter columns 10m tall, spaced at 15-20m intervals on pile foundation. This structure is constructed in the divider space between road lanes. Sky Bus follows existing road routes without disturbing traffic. Bogies Two standard axle bogies provide the drive mechanism. Each bogie is driven by 3-phase alternating current (AC) motor. A third rail provides power. Braking is either regenerative (returning electricity to the grid) with supplemental disc and (emergency) mechanical braking. Power is delivered to the vehicles using brushes or by current carrying wheels. Coaches The coaches are double walled lightweight shells with wide larger windows & are suspended below the rails. The air conditioned coaches have 4m-wide automatic doors. They offer audiovisual information to passengers. Each pair of coaches carries 300 passengers. Each coach is 9.25m long and 3.2 m wide. Trains consist of two coaches, with total length of 18.5m. Traverser The traverser automatically shifts units between tracks. The traverser is a modified form of transverser used in others industries for lifting & shifting objects. In the traverser a platform of track is hung to a bogie which consist of a motor & is also mounted on the track. The traverser acts like a station. A distance of 50m from the last station to the traverser is maintained to provide holding capacity for two units as a third unit is getting traversed in case of unforeseen delay. Station A Skybus Metro car at a station The station is an air-conditioned platform 5.5m above ground. Stations have automatic doors and lifts. A smart card opens the station door. The station fits in a 50m long spot. Margao test In 2004 the Konkan Railway carried out a test of Sky Bus in Margao, Goa with the help of Goa state government. On 25 September, one employee was killed and three injured in an accident, ending the trial. The track ran 1.6 kilometre (1 mile) The test track was supposed to be extended to 10.5 km. Rajaram defended Sky Bus, stating that the accident was avoidable.
