In 1875, the Great Southern India Railway Co. extended its line from Chennai to Tirunelveli and a train station named Kodai Road was built near Ammaianayakkanur village, to facilitate visits to the then new hill station of Kodaikanal.It has been operated by the Southern Railway Zone of the Indian Railway since 1951.
Kodai Road continues to serve as the rail to bus transfer point for passengers going to the now popular tourist destination of Kodaikanal, about 2 hours distant via the SH-156 Ghat Road. It also serves the nearby village of Kolinchipatti. This village is famous for flowers. Among the approximately 30 trains per day that serve Kodai Road is the Pandian Express, which runs between Chennai Egmore and Madurai.
