How to get Suburban train ticket for travelling from Park town station,chennai to chrompet ?...?

I am a entirely new person to chennai . I just wish to know how to get Suburban train ticket for travelling from Park town station,chennai to chrompet ? ... whether there will be too much rush ?...

There is a ticket counter at the station itself. You can purchase
the ticket from park to chromepet at the station counter.
Rush depends on the timings. Office hour rush will be there
on morning and evening.

Do not purchase tickets elsewhere.

tickets can be brought from the park station itself, just as you enter the station, you will find the ticket counter to your left, there might be rush in peak hours ( 8am to 8pm weekdays), if you are returning on the train same day, you can ask for a a chrompet return ( return ticket for same day), save time in standing in line while returning
