My name is Tom and I am the iPhone app product manager at thetrainline.com. We picked up on your post and although a bit late we wanted to first, apologise for poor customer experience you had using our chat service and second, explain how to update the 7 day timetables in the app.

Since reading your post we have re-briefed our staff on the iPhone and because it is such a unique product we have asked them to direct iPhone related questions to iphone@thetrainline.com which is the email address I have used to register this post and the email address that feedback made through the application is directed to.

Now for how to fix the timetables. Unfortunately at present there is no auto refresh functionality (although it is a planned feature in our next big release) so you will have to do a bit of a manual work around.
1. Go into the timetables screen and use the Edit functionality to delete the current timetables.
2. Go back to the home screen and plan a journey for the route you wish to produce a timetable for.
3. Click the download timetable button in the footer and wait for the timetable to download.

Not the greatest process but we are looking to improve. And a bit of info about timetable in general, they update twice a year usually around early December and early May (although some years its only in December).

We will use the Notices functionality to keep people posted on when the next timetable change will occur.

Feel free to contact us on that email for anything related to the app and we will do our best to assist.

Cheers and apologies for taking up a large amount of your wall space,
Tom
