This is why our elders told us not to speak if we don't know about something.

HWH-NDLS is 'totally' for passenger trains, and GC is for mixed traffic. Dear sir, can you tell me which section GC falls on? Okay, let's assume you were talking about the mainline via Patna. From when did Bokaro become a part of the grand chord? Last I checked, it was from Sitarampur to DDU. Perhaps in your world things work differently.

While I agree CIC is mainly for freight movement, what do you mean by it's less important for passenger movement? Even Bokaro is a steel manufacturing hub, and SER is a high freight movement zone. Should they close them for passenger traffic and let the goods running?

Mindset like yours is one of the reasons cities like Dhanbad don't get trains because they're coal loading city, why passenger trains should ply from there. And according to you, we should perhaps seal the Howrah-Mumbai line via SECR, because as we all know SECR is the hub of freights and minerals and ores are much more important than passengers.
