As of now there are only 2 passenger train's on Bangalore Dharmavaram route
1. HUP GTL DEMU
2. BNC BZA passenger
So after entire Bangalore Dharmavaram route is doubled my wish is they introduce few more passenger train's only upto Dharmavaram from SBC And one passenger train between GTL SBC . As there are many commuters who commute upto SSPN
