Lionel's D27 Disappearing Train Layout Revisited

This is a recreation of a well known vintage track design. We are recreating this design for a customer. This is a 4 x 8 foot layout for an O-Gauge train. As a long train disappears into the tunnel it secretly descends down under the table and makes a complete loop and comes back up and out the other end of the tunnel just as if it were going straight through. At one point, only the front of the engine at one tunnel and the caboose at the other tunnel will show and the entire train will be under the layout. Its supposed to be a great illusion. I have not seen it happen in person yet but we will soon as all the track will be laid soon. I am carving up a stack of foam to create a mountain out of it. I will keep you posted on more of the progress! Cheers!
