MGS arrival was 8min before.. n PNBE arrival was 35min before.. so speed was ultimate no doubt about that.. GZB WAP4 was superb in speed.. :)
The worst part was mera coach B3 pathetic condition me tha.. meri seat 71 SL thi jisme side wala borad bhi nahin tha curtains to IR ne pehle hi hata diya hai n coach ki halat aisi.. toilet ki khidki tooti hui thi n bahar ka najara visible tha :(
Overall train got good priority in route till patna (dont know aage ki kahani) :)
