The Mumbai suburban railway or the 'local' is broadly categorised in 2 different ways :
1.The slow local , which stops at every station between 2 major stations.
2.The fast local runs express (skipping stops) until a certain station, and from that station onward runs like a local.
There are 2 classes of travel:
1. The local (second class) and the first class and 4 types of accommodation :
a) general compartment which is mostly frequented by males. It is open to females and children as well.
b) general first class , again open to males, females and children. The coach is designated by red and yellow slant stripes.
c)ladies' compartment, commonly known as ladies' second class. This compartment is reserved solely for females, however male children up to the age of 13 can travel in this compartment. Men are not allowed to travel, and may face a penalty.
d)ladies first class.
The first class is priced approx 10 times higher than the local class, has slightly better seats than the second class. It generally tends to be less crowded. However, during rush hours, it is often equally crowded. So, where you pay just Rs.10 for commuting from one station to the other in the second class and Rs.20 for a return ticket, you pay about Rs.100 for a one way first class ticket. Tickets can be bought for single journey (one way) or a return journey. A return ticket is valid till the next day when purchased on weekdays and till Monday if purchased on a Friday.
The ticket counters usually have long queues, even at 7am in the morning !!!!! So, if you plan to have a longer stay in Bombay, you can even download the mobile app which is m-indicator - Mumbai. To use it, just sign up with your mobile number and add money to your Rwallet, have the e-ticket on your mobile screen and you are good to go :)
