Mysore–Mayiladuthurai Express

Initially, numbered as 31 / 32, this service had 4 slip coaches linked with Island Express at Erode.[1] Later, C. K. Jaffer Sharief, the then Minister of Railways, introduced an exclusive full service between Bengaluru and Trichy as Train No.6531 / 6532 operated by Bengaluru railway division of Southern Railway zone, (before the formation of South Western Railway zone).[2]

Few coaches of the train were amalgamated and bifurcated at Karur for Madurai, numbered as 6531A / 6532A. After changing the train number from 6531 / 6532 to 6231 / 6232, it was first extended to Mysore, then to Thanjavur and to Nagore.[3] On 29 June 2002, the train number was changed from 6231 / 6232 to 6831 / 6832 as the service was transferred from Mysore railway division to Tiruchirappalli Railway Division with stoppage at Maddur was cancelled.[4] The Tiruchi–Nagore service was trimmed for the execution of gauge conversion in the Tiruchi–Nagore section, sanctioned in 1995–1996 Railway Budget.[5] As the Tiruchi–Thanjavur part was completed in 1998, the service again extended back to Thanjavur.[3] After the completion of gauge conversion Thanjavur–Kumbakonam section in Chennai Egmore–Thanjavur line, Lalu Prasad Yadav, the then Railway Minister extended the service up to Kumbakonam,[6][7] which was effected since 9 January 2006 along with change in train number from 6831 / 6832 to 6231 / 6232.[8][9] Further, the service was extended up to Mayiladuthurai Junction,[10][11][12][13] and was effected since 17 June 2006.[14][15] The train number was changed from 6231 / 6232 to 16231 / 16232 since December 2010 onwards as a part of train management system over the entire Indian Railways network.[16][17] There is a constant demand from delta people to divert this train through Salem - Namakkal -Karur line for reduce the travel time and also the fare.
