sorry just rechecked the ticket its Hannover we booked through the db website.
That makes more sense.
They give us 14 minutes to change trains I need to know is it doable?
Under normal conditions this would be enough. However, due to the aftereffects of the recent floods and re-routings, please check your connections and timetables.
And please recheck if there is really no direct train. The usual direct routes do not go via Hannover. There is a deviation on the main route because of flood damage - from Braunschweig trains go via Magdeburg which means an hour or so delay, but the Southern route via Erfurt and Leipzig is not affected.
I don't know when the OP will travel, but there are usually several direct trains a day.
Just checked yesterday, there are also connections via Fulda, Leipzig etc. didn't find a single one via Hanover. Something strange going on there ...Edited: 3:04 am, July 17, 2013
Either they travel in the wee hours ddle of the night, or something went wrong indeed.Edited: 5:42 am, July 17, 2013
When we arrived in Frankfurt I went to the information booth & the kind gentleman there checked our tickets & instructed me to go to the ticket enquiry area & they changed our ticket to a train a few minutes later & its direct to berlin thankyou everyone for your advice.
Very good! It will save you a lot of time.
