2 ) No proposal total politics.
3 ) Clearing track for Rajdhani is not tough but clearing track for crawlers is real pain and as far as reducing congestion is concerned it won't.
4 ) No help for ncr and mostly NR will get choked with this diversion as well.
5 ) 10m 20m will get consumed in MGS BSB only add extra 30...
more... min run in BSB ALD 100 kph section with PSRs present after 4/5 stns.
6 ) rerouting via PPTA HJP is another thing, the rajendra pul is quite old and needs to be relaxed before any mishap occurs.
7 ) Howrah Rajdhani running via Patna and BBS/SDAH running via BSB holds no comparison.
8 ) Ranchi Rajdhani has different route in JH only it serves different cities of JH and BSB is in UP BBS in OR SDAH in WB why should other state rajdhani serve BSB ? Same case with Ranchi Garibrath.
any more question champ ?
