This is obviously a useful app, but there numerous usability problems. Why do I have to use one app (Train Time) for schedule info, then start another app, then re-enter start and end points to buy a ticket? Especially when entering start and end points is particularly tedious in these apps. This wouldn't be such an annoyance if you could control a decent list of favorites. Nope. You get two. With seemingly no way to edit. If there is a way, it's not in the Help or FAQs...
