Sir there is only one way to tackle this
1: connecting barwadih/garhwa to Ambikapur to Korba.
2: connecting raipur to Jagdalpur to warangal and let it come under the ambit of secr.
Then only shortest routes(north to south) from major cities like patna and Guwahati to major metros like hyderabad, chennai, bengalore and kochi be established and the benefit would be to...
more... entire CG as there are many trains to and from these cities.
This two projects should have been strategic for secr but don't know why this zone is sleeping from making new rail corridors since it's inception and only focussing on freight lines.
Also it has been too late now and in near future secr might be loosing trains further.
