DARK Green @SriGuruVenkat ........Extremely Nice by running via ECoR region as Punctuality will be maintained & distance is also less.
Chennai has very less quota in Bengaluru-Patna Sanghamitra EXpress & Ernakulam-Patna bi-weekly Express.
.
This will also provide direct connection for Gomoh-Parasnath-Hazaribagh Road- Koderma-Gaya-Jehanabad to Chennai-Visakh.
