All the trains running in Pollachi - Palakkad Town & Pollachi - Palani sections are still run as special trains. Especially, all the trains in Pollachi - Palani section are operated as special trains for nearly an year. While the trains that are introduced in other parts of India are operated as regular trains the recent past, it's not correct for the railways to continue operate specials in PGTN-POY-PLNI section. For example, Goa Rajdhani express (Train no.s 22414/22413) was introduced on November 15th, 2015 as a regular train.
