Overall this new bridge & Munger bridge will not serve any purpose for NF bound trains..as Barauni Sonpur Section is a huge troll which is presently served by Begusarai Mokama Secn. In future when Munger bridge will be used for diversion Jamalpur & Kiul will prove to be a huge bottleneck.Siliguri to Mughalsarai <16 hrs impossible in distant future.
