Great track. You inspired me to make some new wood extended XlC's to add to my plastic track. I have a question about how you hooked up the cross over section. The Scalextric plastic track has the 2 left and 2 right tracks connected with wires under the track. The red and green sections I added to your photo. How did you make this connection on the new wood section of your XLC. Or is there another way to power those "inner lanes" ?
