ACE is included in the feed, but we did not include it in the animation. We don't currently have geometries for the route alignment (the train tracks), so we'd be drawing straight lines between the ACE stops — didn't look that great in the GIF, so we left it out.
If you want a quite fast and nice solution for aligning routes, pfaedle[1] is a great tool that creates a gtfs shapes.txt by using open street map train track / street data.
