i need to leave cambridge on sunday by train.
the first train to leave cambridge departs at 5:00, and goes to london kings cross.
that will be fine i guess. it will arrive by 19:15, i'm sure?
tr2045 will arrive closer to that time, it arrives at 18:58. would you like tickets for that one instead?
yes, let's go ahead and book that.
my apologies, i believe there was an error in the database lookup. tr2045 is not available but tr3353 arrives at 17:51 on sunday. shall we book that instead?
yes, please give me travel time and departure time, please.
certainly. the departure time is 17:00 and the travel time is 51 minutes. i have booked your ticket. the reference number is bjj3gxmx. can i help with anything else?
no, that's all i need, thank you.
thank you for using our system!
thanks for your help bye!
you are welcome. goodbye.
