I am looking for a train that departs from cambridge after 14:00.
There are hundreds of those! What day are you traveling and what's your destination station?
I need to leave from Kings Cross on a Saturday please.
Sure, Are you leaving, or going to london kings cross?
I am going to London.
Okay, I'd recommended TR6203 leaving at 15:00 and arriving at 15:51, total duration 51 minutes. The price is 18.88 pounds. Would that work for you?
Yes thank you very much that's all I needed!
You're very welcome. Enjoy your trip. Goodbye!
