Where are you departing from? We have 19 different trains along that route for Sunday. Do you have a specific time in mind?
I need to find a train departing on Sunday that is going to Cambridge. I am departing from leicester. Yes I need to leave after 18:30 on sunday and I need to make a reservation for 8 people. Can you give me a reference number for the booking?

There are five trains that meet your specifications. The earliest leaves at 19:09 and arrives in Cambridge at 20:54. Would you like me to book this?
