am looking for a train. The train should leave on monday and should depart from cambridge.
There are many trains available.  Do you have a specific day or time in mind? 
I would like to travel on Monday after 12:00. 
What is your destination?
I want to go to leicester.
The next train after 12:00 leaves at 12:21. Would you like to purchase tickets for that train or is there anything else I can help you with?
I'd just like the travel time and train ID for that one please.
12:21 and time is 105 minutes. May I hemp with anything else ?
Yes, can you please tell me the train ID that departs at 12:21? 
My apologies, the ID is TR4096 and the duration is 105 minutes. Is there anything else that I can help you with?
That is all for now. Thank you so much for the information.
You're quite welcome. Have a safe trip. Goodbye.
