Crashcoaster on coasterforce posted this and tbf i think he could be spot on.
Complete the first section of track. arrive in the launch area, go to launch forwards it doesn't make it, launches backwards then does the next part of the track up until the lift hill. hits the lift then rolls back down the lift hill back through forwards, then hits the launch and back to the station.
Then I've suggested the back bit on its own could just be a maintenance shed if it is running 2 trains at a time.
