The Mumbai suburban local trains have 2 classes – first class and general (second) class. First class tickets are priced much higher than the regular ones. If you’re travelling on the western line during non – peak hours, it would be advisable not to waste money and buy the regular ticket and travel in the second class, but if you’re travelling during peak hours, it is always advisable to buy a first class ticket. The base fare for a first class ticket is Rs 41/-. Even if you wish to travel from Churchgate to Marine lines, your base fare would be Rs 41/-.
Generally, people who travel on a daily basis buy monthly season tickets, which turn out comparatively much cheaper. The first class fare for a monthly ticket from Churchgate to Borivali (western line) is Rs 580/-.
