JTJ is not a big town Machi. The station is very big because of the merging of two important lines. The town is very small. I have been there once. Within one hour you can visit the entire town. TPT is bigger. Most of the passengers alight/board at JTJ are from TPT. But KPD is very big place . As vellore is near by . Vellore has VIT , government engineering coll and the most important CMC where thousands visit. So only i said Machi
