The Erode–Kangeyam-Dharapuram-Palani line is a proposed railway line from Erode Junction (via) Kangeyam,Dharapuram to Palani in the state of Tamil Nadu. It is a part of Southern Railway zone of Indian Railways. This line upon construction will improve rail connectivity of the Pilgrimage center with Chennai and other states of the country. It was a revised version of the original pre-independence proposal by the British.

History
The revived proposal was initially prepared way back in 1915 to link Palani and Nanjangud via Erode and Chamrajanagar. The route was planned via Dharapuram, Kangeyam, Erode, Gobichettipalayam, Sathyamangalam and Chamrajanagar. The British had conducted surveys in 1922, 1936 and 1942 and survey stones were also laid for the proposed railway line. But after that the Erode-Chamarajanagar project pre-independence proposal did not take off.  In 2005 it was split into two different projects. One being the Erode–Palani line and the other Erode-Chamarajanagar line. The later one connecting Erode with Chamarajanagar has been split up into two sectors namely Erode-Sathyamangalam and the Sathyamangalam-Chamarajanagar section which is covered in the South Western Railway Zone's recent proposal of Bangalore-Chamarajanagar-Sathyamangalam line.

The recent Survey has been completed for the proposed Erode-Palani Rail link in the financial year 2006-2007 and estimated a sum of Rupees 289 crores.

Route
The proposed 91.5 km line goes through Erode Junction-Chennimalai-Kangeyam-Uthiyur-Dharapuram-Palani in the districts of Erode, Tiruppur and Dindigul.
