CPA can be used as Terminal point for Eastern bound trains.
Example:-
1) 12209 /12210 Kanpur Central - Kathgodam - Kanpur Central Garib Rath Express to CPA
2) 22445/22446 Kanpur Central - Amritsar - Kanpur Central Weekly SF Express to CPA.
3)...
more... 14123/14124 Pratapgarh - Kanpur Central - Pratapgarh InterCity Express to CPA
4) 14101/14102 Prayagraj Sangam - Kanpur Central -Prayagraj Sangam InterCity Express to CPA etc.
Can be extended from CNB to CPA which will reduce load on CNB.
GOY will take time because NCR is busy in handling Freight trains & Prayagraj.
Rather than Redeveloping New Terminal points in NCR.
