Hi, I was just wondering - has anyone yet considered whether there might be a way to "9voltify" the LEGO 7996 set (switched rail crossing)? I mean, there we do have a very useful piece of track, however it is only usable for RC trains so far. What (...) (16 years ago, 31-Dec-07, to lugnet.trains)

Jeffrey- Of course, there's the "easy" way: Simply use two motors, linked by a wire, and separated by enough distance to cover the non-conductive gap caused by using a 7996. We have tried this and it works fine (and also improves operation (...) (16 years ago, 10-Jan-08, to lugnet.trains)

(...) Running wires between cars is probably not as tough as getting the lead from the motor to the car or engine. Although LEGO made a train headlamp kit, the wire coming off the motor connector tended to get in the way, especially on turns. We (...) (16 years ago, 11-Jan-08, to lugnet.trains, FTX)

(...) I wish that I had read this a few months ago (when I should have). I just bought a 7996 with the intention to convert it to 9V. I am very disapointed that you can not have both of the parallel straights switched to go straight at the same (...) (16 years ago, 8-Mar-08, to lugnet.trains)
