Can you help me find a train going to london kings cross leaving on thursday? Did you have a certain time you needed to leave or arrive by? I would like to leave cambridge and arrive by 20:15. I could suggest train TR8636, which arrives by 07: 51, should I book? I don't need the booking yet. You've already give me the train ID. I just need the departure time and the travel time. Thanks. you leave at 7 and arrive by 7 51. What is the travel time? I'm also looking for information on a hotel, carolina bed and breakfast. The travel time is 51 minutes. As far as that hotel goes, it's a moderately-priced 4-star guesthouse on the east side. I want to book for 5 people, 4 nights, starting from sunday. Booking was successful.
