It would be better if bi weekly 16351/52 NCJ CSMT is made to run via MDU, SA, KPD, TPTY. This will give a daytime link for Southern TN to KPD.
At present, there is no convenient train from TEN/TN/TCN to TPTY.
To compensate the loss for Kanchipuram to Trichy passengers, a bi weekly can be run from Mumbai to Rameswaram...
more... via GTL, RU, CJ, VM, TPJ, KKD. For this, LTT MDU slot can be used.
