Its Urgently needed to be done.
The Hwh Patna Rajdhani is an unnecessary thing ER doing. It should stop sending that Sunday Holiday Rajdhani to Patna, and make the Hwh Rajdhani via Gaya a Daily affair.
Regarding Poorva, the ER should make 12381/82 a Four days a week and 12303/04 to a Tri-weekly train. And also should remove the DNR, ARA, BXR halts and instead should provide these 3 halts to 12393/12394 which starts from Patna but serves only Patna. Pity.
