What day would you like to travel? That's leaving after 16:00, yes? Or did you mean arriving after 16:00? If leaving after 16:00, the TR5212 leaves Cambridge at 17:59 and arrives at London Liverpool Street at 19:27.
Hi there. Can you help me find a train going to London Liverpool Street? I would like to leave from Cambridge on Friday. Any train after 16:00 should be fine. Yeah, that sounds good. Can you get me two tickets?
