It's official. Monorail is coming to town. Even before completion of a feasibility study, Delhi government has decided to implement the transport system as a 60-km feeder service to various stations of Delhi Metro. This, despite the fact that internationally, the system has only been implemented in amusement parks or connected tourist destinations. Considered an eco-friendly mode of transport, monorail is usually an elevated network which runs on a single track and has tube tyres.
