Hi I'm looking for a train departing from Cambridge that leaves after 17:15. What is your destination? I will be going to bishops stortford. I would recommend TR1567 which leaves Cambridge at 17:29 and arrives at Bishops Stortford at 18:07. No, can you find another one please? The next one after that departs two hours later. Would you like to reserve a seat on either train? Yes, either train would be fine. I have booked your seat on the TR1567. Total fee is 10.1 GBP payable at the station. Reference number isCWX49ENL Thank you. Could you also recommend a college in the Centre to visit and provide the post code? Christ's College would be great, their postcode is cb23bu. Is that all you need?
