Task-oriented dialogue about: attraction
train

I'm looking for colleges to visit in the centre of town.
There are 13 colleges in the centre. King's College and Saint Catharine's College are on the same street and both have free admission.
Can you provide the phone number and post code to the attraction?
King's College is cb21st and their number is 01223331100. Saint Catharine's is cb21rl and their number is 01223338300.
What is the entrance fee?
Both are free. Is there anything else you'd like help with?
Yes, actually. I could use some help finding a train to take me from Cambridge heading to Bishops Stortford.
What day and departure time do you prefer?
I want to leave on Saturday at any time after 21:15.
How many ticket will you need?
I would just like to know the travel time of one or more of the trains.
They are both 38 minute trips
Thanks. That's all the information I needed today. I appreciate your help.
You're welcome. Enjoy your stay in Cambridge. Good bye!
