I need help finding a train leaving Cambridge after 20:45. Many trains leave Cambridge around 20:45, what is the destination? I need to get to london liverpool street. I have several options for you, and the price and exact departure time varies by day of the week. Do you have a day preference? I would like to leave on Thursday Train TR3695 leaves 21:59 and arrives on 23:27. Would you like to book it?
