Chennai Central railway station, Colonial railway terminus in Park Town, Chennai, India

Chennai Central is a red-brick railway station in Park Town, Chennai, designed by George Harding in a mix of Gothic Revival and Romanesque styles. Its long facade has rows of arched windows, a central tower with a clock face and a white steeply pitched roof, and two symmetrical towers with white arched roof sections. Signs at the base read "CHENNAI CENTRAL" and "புரட்சி நடிகர் எம்.ஜி.ஆர். மத்திய ரயில் நிலையம்".

The station opened in 1873 to relieve congestion at Royapuram harbor station and quickly became the main hub for trains between South India and the rest of the country. Over the decades, the facilities expanded several times to meet growing traffic demands.

The station's official name since 5 April 2019 honours former Tamil Nadu chief minister M. G. Ramachandran, and the long form appears on the red signs at the base of the facade. The building was earlier called Madras Central, then Chennai Central after the city's renaming in 1996.

Trains operate from early morning until midnight, with peak hours in the morning and late afternoon. Signage is available in English and Tamil, and most ticket counters are located on the ground floor near the main entrances.

In 2014, this station became the first in India to offer free Wi-Fi for all travelers. Since then, thousands use the network every day to check connections or bridge waiting times.
