Hello friends. The name of this train is just "Pune-Darbhanga-Pune" express and not Gyanganga Express as shown. I have seen the boards of this train and also it shows as PUNE-DARBHANGA Exp. The 22131 Pune-Manduadih Express is actually the Gyanganga Express. announcement are also made same at all the stations.. So I am going to change the name now. Any comments/suggestions welcome.
