Suvitha trains in this route is operated in the circuitous main line route with extra distance ,extra running time and extra fares .So this service is forced to the travelling public from Tirunelveli-Chennai Egmore sector with extra distance ,extra running time and extra fares . This is unwarranted.Separate service may be introduced in the Chennai-Thanjavur-Trichy sector..Chennai Egmore-Tirunelveli Suvitha should be operated via chord line with lesser running time over the SF running time since SUVITHA fares are collected more than 3 times over the normal fares.
