Multiple Euro Fighter trains?

Hello Is there a script or a way to have multiple Euro Fighter trains so I can make a Gerstrauler Infinity coaster like The Smiler and that new Scandinavian one just built.

or is there a way of adding a base to a floorless coaster design?

You can make a 3d's floor and then use the ''attachobject'' script (which is and in game one I think) and then place it next to the floorless trains. If it ends up sideways it means that you need to rotate the object in the original 3d's model file.
