I have a train that departs at 15:40 and arrives in Cambridge at 18:23. Will that do?
That would work just fine. Could you tell me the price and travel time for that train?
The TR5385 has a travel time of 163 minutes. Would you like me to book you some tickets?
No, I don't want to book today. Could you just give me the price for that train? I think that is all I need today.
