i'd like a train to london kings cross to arrive by 21:15.
sure, which day would you like to travel?
i am travelling on thursday and going to cambridge.
might i suggest train tr6595 leaving cambridge at 19:00 and arriving at london kings cross at 19:51. would that work for you?
yes, that does work. could you book it for 1 person please?
okay, i went ahead and reserved your ticket for train id tr6595. the cost will be 23.6 gbp payable at the station, and your reference number is gktt3otz .
that's everything i needed. thank you!
you're welcome. have a great day!
