The Tamil Nadu Government is now claiming they went with a monorail because they feared a Chennai earthquake. Obviously, when the Big One hits, the best place to have multi-ton metal vehicles is balancing over the heads of pedestrians (not safely ensconced in pressurized, quake-resistant underground tubes).

Also, after a government assembly where critics were denied the ability to raise questions, PMK member G. K. Mani revealed that the monorail "bogies" the government plans to purchase are currently sitting abandoned in Malaysia. It's unknown at this time if they're in the same state of disrepair as the ones found in France, but considering how desperate Lava is to unload them, it would be wise to check the cars for vagrant orangutans before signing for them.
