Metro rail India has been a success story. Yet cities with lower projected ridership are also aspiring for rail based mass rapid transit system, being safe, punctual and reliable. The wish list can be fulfilled by Light Urban Rail Transit System named "Metrolite" policy by the Ministry of Housing & Urban Affairs (MoHUA) which proposes lesser capacity, at less cost, and low O& M costs. All Tier Two cities and suburban areas of Metropolitan cities are the key clients as the systems appears viable. 'Metrolite' would also act as feeder system to high capacity Metro.
