Mumbai is probably the best-connected city, you have a very regular and clean bus service BEST that connects Mumbai right across. They have a few AC buses too that ply from Colaba to Andheri, very comfortable on a hot and humid day, and not that expensive either. The two train lines Western railway connecting Churchgate through to Andheri and Virar and the central Railway connecting CST to Thane and Kalyan and Neral are very efficient, and probably the cheapest way of getting around. The third line, Harbour line, connects CST to New Bombay, CBD, Panvel, Andheri and Bandra. This line however is not very punctual and the first to go under with a heavy downpour. However try and avoid the office hours on western and central lines. Taxis are available through the night, though you will have to a pay a surcharge of 25 per cent after midnight. Most taxi drivers are extremely friendly and will not jip you. Mumbai also offers an AC taxi service called cool cabs, for those of you who would prefer it. Auto rickshaws are yet another means of transportation; however they have licenses to operate only within and beyond the suburbs of Bandra.
