I am looking for a train departing from london kings cross.
There are 70 trains departing, what is your destination?
I would like to arrive in Cambridge on Tuesday by 17:00.
Of course. When would you like to leave?
It does not matter as long as I am in Cambridge by 17:00.
Sure, train TR0269 arrives by 16:08. That is the last train to arrive by 17:00. Would you like to book it?
Yes, please book the train for 4 people.
That booking reference will be F6JIDI3M. Is there anything else I can help you with today?
No, that's all I needed. Thank you.
Okay.  Glad we could help.
