Designed to accommodate 150 commuters and travel at speeds as high as 100 kmh, Sky Bus railway transit coaches built for India's Konkan Railway (Mumbai, India) by Kineco Pvt. Ltd. (Goa, India) are expected to ease public transportation in congested metro areas. Coaches will have 4m/13.1-ft-wide sliding passenger doors and travel in tandem above existing roadways, suspended beneath an overhead concrete-enclosed railway supported by vertical concrete columns. Inside the track enclosure, electrically powered "bogies" will travel on a patented "floating" track system.
