What about the highest revenue making Guna-Jhansi-Kanpur section? do you even know the importance of this train on the route.
Gwalior already has a train for ADI, then why to divert this train? even ETW-GWL electrification is not completed for your FYI.
Kanpur-Jhansi-Guna route is way more speedy than slow Etawah-Gwalior-Guna route, and additional congestion in Etawah-Kanpur is also their you can't deny these facts.
