I am looking for a train to ely on wednesday.
Where are you leaving from?
should depart from cambridge at 17:15
I can get you on a train leaving Cambridge at 17:50. 
That won't work I need to arrive by 17:15.
I have the TR1549 leaving at 17:50 and it will be arriving at 18:07 is that a little better for you?
No that still won't work. Is there anything earlier please?
I've got a train that will arrive at 16;07 or if you prefer earlier, 14:07. would you like me to book one of those for you.
As long as I am there by like I said earlier, 17:15 so yes the 16:07 will work for me. I am also looking for attractions in south
How many tickets would you like to book?
I don't need to book any train tickets, thanks. What attractions do you recommend in the south? 
There are 8 attractions in the south. I would recommend the Byard Art museum which has free admission. Do you need a booking , or need help with anything else? 
No, that's it for today. Thanks for your help.
