Send me the literature review of skybus technology as soon as possible

The Skybus Metro was a prototype suspended railway system invented by Indian technologist B Rajaram with the Konkan Railway.The system consisted of an elevated track with the cars suspended below, similar to the Schwebebahn Wuppertal or H-Bahn systems in Germany.A 1.6 km (1 mi) test track in Margao, Goa started trials in 2004, but on 25 September, one employee was killed and three injured in an accident when the coaches hit the concrete track pillars.The test track was supposed to be extended to 10.5 km, but no progress has been made since the accident, and the system has not been adopted anywhere else in India.In 2013, the Konkan Railway announced the demolition of the line.
