Once the traditional RRI signalling system is replaced by Electronic Interlocking system with a fully computerised Visual Display Unit at PGT and opening up of the 5th platform, the train handling capacity of Palakkad Jn. would improve manifold. Expecting the Chennai Palani Express to get extended to Palghat similar to Amrita Exp being extended to Pollachi. Also, in the new TT w.e.f Oct 2016, new trains in the PGT POY PLNI route should be included..
My Suggestions are:-
Mangalore/Kannur- Madurai Intercity Express
Kannur...
more... Palani Fast Passenger DEMU
Ernakulam Madurai Express
Palghat Rameswaram ONT Express.comments are welcome... thanks
