Tearloch33 Posted January 11, 2011 Posted January 11, 2011 I recently purchased a LEGO RC #7996 Dual Cross-over, and now I am looking for solutions on how to discretely modify it to allow all 4 switches to operate independantly to allow for both sides to allow straight travel simultaneously. Any suggestions? Quote
JopieK Posted January 11, 2011 Posted January 11, 2011 I use wires (nylon) hot glued to the track (leaves no permanent damage) and a small motor. but it still is a challenge. Quote

andythenorth Posted January 11, 2011 Posted January 11, 2011 Use 2 more turnouts + some straights to build a passing loop around the crossover It sounds dumb, but actually gives some interesting switching possibilities. I might post pics. Quote

I think I know whose it was and I'll email him for details. Quote

I think I know whose it was and I'll email him for details. I think I have seen the photos you mentioned. He modified the springs to allow a center position, making it a 3 position switch instead of a 2 position switch. He gave instructions, but I would love to see a photo with the switch point removed to see the spring set up before I undertake his suggestion. I did find that you can set this switch up to run two tracks at the same time as long as the trains go in opposite directions. My only issue with that is that my son loves to make his train go backwards, negating the usefulness. If anyone has a picture of the spring setup inside the switch, I would love to see them. My other thought was to cut the slide bar connected to the switches, and modifying the mount to hook 2 throw bars in the middle. Any thoughts? Quote

Snapshot Posted January 15, 2011 Posted January 15, 2011 (edited) A interesting link : http://news.lugnet.com/trains/?n=30338 That's from Mark Bellis who also has the photo on Brickshelf. Use the two bits of info together and you should be there. He also has more photo's here. I'm getting out my modelling saw, knife and files..... Edited January 15, 2011 by Snapshot Quote
