i'm looking for a train to broxbourne.
where would you like to leave from, and what day and time would you like to travel?
i'm going to be leaving from cambridge. i need to leave on tuesday by 13:00.
is there a time you would like to get there by ?
i don't have an arrival preference.
the earliest train leaves at 5:01. the latest train leaving by 13:00 would depart at 12:01. there is also one that leaves at 13:01. the trains run every hour.
actually, i'd like to arrive by 13:00. could you give me the train id for the train arriving closest to that time?
train id is tr6357. would you like to book ?
