Bombay (Mumbai)

Several systems were in the planning stages for this city on an island off the west coast of India. One plan called for a 17.5 km, 20 station subway between Bandra and Colaba. Another called for an elevated line between Bandra and Kurla. A once  promising one was the home grown Sky Bus, a made in India monorail, with three lines.

Update 5/2003: An elevated 10 km LRT will be built between Andheri and Ghatkopar via Asalpha, Marol, Chakala and Saki Naka. The SkyBus was rejected because the technology of a vehicle running over air is yet unproven. Described as "not for for mass transport", it is reminiscent of the way your bank will only loan you money only when you don't really need it.

In January 2004, a master transit plan, including a 146 kilometer metro, was unveiled by the Mumbai Metropolitan Region Development Authority (MMRDA). Included was 32 km of subway.

In June 2004, government approval was given for a 13 station  elevated light rail line between Ghatkopar and Versova.  The line is expected to open in 2008. It will be mostly elevated,  except a short stretch underground where it crosses the Western Express Highway. A short spur will also connect with  Mumbai's international airport.

In April 2005, Mumbai contracted with Delhi Metro Corp to build a full fledged subway system. The ambitious 9 line system will begin construction in late 2005. Eleven stations and 8 km of the initial line will be underground.

The 145 km metro wll also include a 13 station elevated light rail line which was approved seperately and integrated into the project. The metro's first 11 km line is expected to open in 2011.

The Bombay subway map also bears a frightening resemblance to the New York City subway.

Bombay currently has an extensive commuter rail system, but it's in no way a subway.
