So far 16 states have agreed to have a joint venture with Railways for creating more infrastructure facility, Prabhu told reporters here.
"If Tamil Nadu also agrees, it will help us expedite the process for more infrastructure for the state", he said.
"We have written a letter to Chief Minister (Jayalalithaa) to explore the possibility of redevelopment of the railway stations in Tamil Nadu," he said.
"There can be many opportunities in addition to what we are already doing," Prabhu said.
The ministry is negotiating with various industrial sectors, including steel industry, for its transportation, as the freight charges have been reduced to attract more cargo, he said.
