I'm looking for a train to Broxbourne. What day would you like to travel on? I would like to leave on Tuesday after 21:00 from cambridge. Can you accommodate? Yes, there are trains departing at 21:01, 22:01 and 23:01 on Tuesday. Which time would like? 2 tickets on the 21:01, please. And can you give me the reference number once that's booked? I have booked your tickets. Your reference number is LJWDINYN . Is there anything else I can do for you? Thanks. I would also like to go a museum on the east side. I found 4 museums, I'd recommend the Cambridge Artworks as it is free to enter. Would you like any information on it? Just the address, please. They are located at 5 greens road.
