Here's how to solve that problem.
Translink has a page called stops and stations. 1. Go to it. 2. Enter the name of your nearet train station or bus stop. (If you just enter your street name, it will give you a map to choose from). 3. Select the stop/station you're interested in. It will give you a list of upcoming buses/trains from that place.
At home and at work I've bookmarked my regular stops and stations. It's good to know just how much time I've got - so I always show up just at the right time. :)
