I am planning a trip in Cambridge
That sounds like fun! What information can I help you find?
I need to first find out what train will take me away after I am done.  I need to get to Peterborough on Sunday by 21:45
Where will you be departing from?
Departing from Cambridge. I need the departure time, train ID and price.
Okay, we've got a few options.  The best looks like train TR6958 that leaves Cambridge at 20:34 and arrived in Peterborough at 21:24.  The price is 13.2 pounds.
Thanks! i'm also looking for a place to stay in the east.
I found the express by holiday inn cambridge. It is a 2 star  expensive hotel free parking and internet. The address is15-17 norman way, coldhams business park.
