use a zero distance switch to allow the wireframe train to switch over to the launch track.

the black line shows the path of the wireframe train. the fake train(custom train shown in colour) would stop where the two tracks cross over, it would then have a simple rotation animation so it turns to face the direction of launch then proceed.
Amazing animation


after the wireframe train is in position, the custom train would then attach back and continue the layout.
I hope its understandable, i would actually make it all work buts its real late.
