how hard is it to install into the small engines and toby. and how simple is putting Decoders into any  non-DCC locomotive.

what is gapping cause i'm trying to insulate the turnouts with plastic frogs and was wondering what in the world is it.

Can you buy the locomotive after the set is discontinued? I hope so cause that class-J is a wonderful locomotive.

the turnout has a remote control box to change tracks and it has a plastic frog. what I would like to do is turn it into an isolated siding so that the two trains on the siding and main line will not derail each other.

yes this a turnout and the track i'm using is bachman E-Z track.

I was wondering if you can change a switch into an insulated one, could you also tell me the most quickest and cheapest way to convert it. Thanks for your help!
