Sources within CMRL stated that metro projects in Chennai, Coimbatore, and Madurai are currently receiving priority. Recent studies and inspections have been carried out for metro proposals in Coimbatore and Madurai, but there has been no significant progress made for Trichy. The estimated cost of the Trichy metro project is Rs 109.17 billion.

A senior CMRL official noted that implementing metro corridors in Trichy would not encounter major obstacles, as there are no serious overlaps with existing flyovers or overbridges. However, the official emphasized that securing funds for the project is a significant challenge. The official further mentioned that the Trichy metro plan has not been prioritized or fast-tracked by the state government and is currently on hold.

The DFR outlines two metro corridors that would span 45 km across Trichy city. According to CMRL sources, Corridor 1 will be 19 km long, connecting Samayapuram with Vayalur and featuring 19 metro stations. Corridor 2 is proposed to be 26 km long, linking Thuvakudi with Panjapur and having 26 metro stations.
