The daily ticket sales at Tambaram fetch ₹ 1 million, half of which comes from suburban travellers. It is the second most revenue-generating station in Chennai after Moore Market Complex. A total of 52 trains pass through the station.Tambaram Railway Station divides Tambaram into East Tambaram and West Tambaram. There are nine platforms in the station. Platforms 1-4 are used for suburban trains between Chengalpattu and Chennai Beach and platforms between 5 and 9 are used by the suburban electric trains between Chennai Beach and Chengalpattu and Tirumalpur and also long-distance express trains. Most of the suburban electric train services originating from Tambaram to Beach and Chengalpattu leave from the first two platforms. There is a foot overbridge connecting East and West Tambaram with access to all platforms. In 2008, Southern Railway started building an additional platform at the westernmost side of the railway station, making Platform No.1 a double-discharge platform, a design that helps commuters to alight on either side of the train, similar to the one at Park railway station, where the passengers could alight on the western side for quicker access to Chennai Central.
