Here's a video showing the Waterloo/Kitchener service in action:
A couple notes:
1. The vehicle itself isn't much different from a bus. What makes it valuable is the dedicated ROW which allows it to move quickly around town. I love the idea of trains but having dedicated throughfares is what makes it truly valuable.
2. On the other hand, there's a 'je ne sais quoi` about rail that I've always loved...
3. The stations and interface are very clear and straightforward, with tickets etc.
4.The service runs through what must have been old rail ROWs, but also suburban side streets, or taking what would be a dedicated bus lane here in Victoria. The willingness of W/K to implement this seriously is good. The embedded track means that you can also have modal share on the same roads. Toronto's streetcars do this, and LRT in cities like Salt Lake also do this...
