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.
