I've got a MHT locomotive w/ ProtoSound 2.0. I'm running it on Lionel 0-27 gauge track because i need the #27 curves and the smallest curves MHT offers are #31. The train works fine. :thumbsup: Anyways...my problem is that the Lionel switches have a nice feature on them that automatically triggers the switch once the loco touches the track so it does not derail itself if the loco is entering the switch from the opposite side from which it exited. The MHT loco dies (temp. looss power and gets put into neutral) sometimes when it passes over the switch. The other problem is that the twin coil packs in the switch are activated the entire length of the train as it passes by (you can hear the coils buzzing). How can I modify the Lionel switches to make this feature work with my MHT loco? I am not afraid of a soldering gun, plastic welder, MIG welder, whatever I need to do to make this work!
