Yet the line is still active and the intention is to connect with the south of the city. Another line's also projectedbut is not know when it'll be finished yet. The ticket costs about 10 rupees.

Bus

BEST  
Mumbai bus fleet is managed by the company BEST. The buses are red and have one or two stories. They go all over the city and it’s been said that it's the most organized and reliable bus network of India, even though you need to be patient with timetables and traffic jams. The good news is that fees are very cheap.

Rickshaw

In some areas of the city, especially in the suburbs, it's still possible to catch the famous Rickshaws, a kind of motorcycle with three wheels which can accommodate up to 3 people. Prices tend to be
discussed before making the trip, but now most of them work with a taximeter. 

Cabs

Classic Cabs of the city can be recognized for their black and yellow color and for being Fiat brand. Currently you can also find the "minicabs", which are private companies and are painted in green and silver or red and yellow. The so-called "cool cabs" are blue and usually have air conditioning. Most taxis have taximeter, but it can't hurt to keep an eye on it from time to time to check whether the price is right. 

Train

It has several lines but the main ones are the Railway Central and Western Railway, and many stations where other long distance lines concur.
