So this is an idea I have had since rct2. Almost all coasters with high capacity systems have service bays, and these also contain extra trains for capacity and to make sure if other trains have issues, they can replace them. What if we can make use of this, and allow for extra trains to be stored in a service bay, and they automatically put more trains on circuit for longer queue times. Also another thing that would be awesome to implement is to add switcher tracks, like this. This would allow for what I mentioned above, but also allow for dual-station boarding. Imagine the possibilities with the coasters if we implemented these things?
