Task-oriented dialogue about: train

I need to book a train for 8:45 to go to london kings crossing.
What day are you planning to travel?
I would like to travel on Friday.
I'm sorry I dont' have any trains for that day. Would you like to leave at a different time?
I will be leaving from Cambridge on Friday.
The earliest train I have is at 09:00. Is that ok?
That's fine. Can you give me the arrival time, travel time, and train ID please?
TR2000 takes 51 minutes to arrive at by 9:51. Would you like me to reserve this for you?
Nope, that's all I needed. Thanks!
Thank you for using the Cambridge TownInfo Centre, and have a great day!
