This train is one of the best train to Howrah.Honestly saying,opt this train instead of jnaneswari if having ample time.
I travelled recently on 12151 from Lokmanya Tilak terminus to howrah.Date 18/10/17.It arrived LTT late by 60 mins and departed at 9.40 pm,but still managed to arrived Howrah 8.20 am!!!.Food is not up to the mark,but overall a speedy journey though,overtaking the ontime 12809 mail at Jalgaon,Gondwana express near Bilaspur shows the priority.For railfanning too it's a good train.
Details about my journey on this train will be uploaded soon :)
