I need to get to Bishops Stortford for a very important meeting. Can you find me a train to get me there by 11:30?
There are 21 trains making that trip, what day would you like to go?
On Saturday. And could you tell me how long that trip takes?
There are three trains that will get you there before 11:30. The trip lasts a total of 38 minutes. How early would you like to leave?
