Here’s what I found on the Chennai Local (Suburban) Train Timetable for 2025:

General Schedule Overview

The South Line (Chennai Beach–Tambaram) operates its first EMU at around 3:55 AM from Chennai Beach, with the last service at around 11:59 PM. Peak hours see trains every 7 minutes, while early morning and late-night gaps stretch to 20 minutes.
On the Tambaram–Chengalpattu section, trains start from around 4:50 AM, with the last one at 11:40 PM; during peak hours, frequency is about every 15 minutes.
The reverse runs (Chengalpattu to Tambaram) begin around 4:05 AM and continue until 11:10 PM, also on a 15-minute headway during busy times.

AC EMU Services Update

AC EMU services in the Chennai suburban network underwent a schedule revision effective May 2, 2025, per an official Southern Railway update. If you rely on AC trains, you’ll want to check the latest timing details on Southern Railway’s platforms.
