I need on that will leave London after 21:00.
I have two trains that will leave after 21:00. One leaves at 21:39 and one leaves at 23:39. Which would you prefer?
What time does the one that leaves at 21:39 arrive in Cambridge? Also, what is the train ID?
The train ID is TR5906 and it arrives by 23:07 in Cambridge. Would you like me to book that one for you?
