I would like to leave after 11:15.
I have many available. Is your destination Cambridge or do you have another location in mind?
Yes I would like to go from leicester to cambridge and leave after 11:15 please.
The first available train leaving after 11:15 would be train TR4354 which departs at 12:09 and arrives at 13:54. Would you like me to book you a ticket for this train?
