The trains will ease travel in the crowded southern districts of Thiruvananthapuram, Kollam and Alappuzha.
"This project would be a joint initiative of the centre and the state. The Mumbai Railway Vikas Corporation (MRVC) will be submitting a detailed project report by December," said Chandy to reporters after meeting Southern Railway and MRVC officials.
"This project once commissioned will bring down the traffic on the roads in these two sectors," Chandy said.
The project has been designed to supplement the existing trains that run on these sectors, he said.
Chandy asked top railway officials at the meeting to run superfast trains in the northern districts of the state.
