Three prospective routes have been identified as in-demand corridors for the planned metro track network in Trichy, according to a comprehensive mobility plan (CMP) for strengthening the public transportation infrastructure finished by Trichy Corporation through a Bengaluru-based consulting firm.

The total length of 68 km of the identified public transport corridors can be used as a master plan for the Trichy metro proposed by the Chennai Metro Rail Company (CMRL).

Three routes were identified as in-demand metro lines based on hourly passengers per hour direction data (PPHPD) collected and estimates made up to and including the year 2042. After passing Srirangam and Thillai Nagar, Route One would connect Samayapuram in the northern suburbs with Vayalur in the western suburbs over a distance of 18.7 kilometers.

The longest of the three routes of 26 km is planned for Route 2. By the Central Bus Stand, it will link Thuvakudi with the Panjapur Integrated Bus Terminus. Route 3 will travel 23.3 km, linking the semi- ring road and the international airport at the Trichy railway junction with Panjapur. Integration of three metro corridor alignments is necessary at three locations. Potential intersections include Central Bus Stand, Junction, and Panchapur IBT. The number of bogies in the metro train and the type of network, Metro Lite or Metro Neo, for Trichy, will be created based on the city's capacity for visitors.
