Trichy and Chennai will be connected through Mayiladuthurai by trains starting from Jan 2008.  The route is getting converted from Main line to Broad gauge now by Railways as part of Standardisation of rails. The estimated project cost is about 270 crores and work is in full flow there.

Apart from giving more choices and trains for people  in Trichy and Madurai for connections, this line will be a boon for passengers from Kumbakonam, Thanjavoor and Mayiladuthurai as this will shorten their travel time to Chennai.
