Hey everyone!

A ride which I have built several times is a dueling and an inverted coaster which share the same track! The sitdown coaster will be on top, and the inverted coaster will be on the bottom of the track! It can be very tricky to keep the trains synchronized throughout the track, especially through inversions.. But it will look spectacular if you can manage it! Probably the most time-consuming part about making a ride like this will be the supports.. For a ride like this to work, the track would have to be suspended from the sides! 

There is actually an easy trick to synchronize the rides without the stations being next to eachother, which I didn't know yet when I wrote the tutorial: Simply copy and paste a piece of the front of both stations next to the other station, and make the piece invisible! Now the rides will think they are next to each other and they will synchronize! This should allow you to make the stations on top of each other!
