Im curious is this possible to do and what will I need to do so .I have alot ot extra mth realtrax and want to use it if possible with my lionel fastrack track,can this be done,and how if possible.
It’s been about 40 years since I’ve worked with anything Lionel, But have you considered soldering the together?
You should post this question on the Classic Toy Trains forum, that’s where the Lionel and MTH guys hang out.
As far as I know, there’s no direct way to connect the two. Both systems, however, have a transition section to tubular track. It would be possible to go from Fastrack to tubular and then back to Realtrax. Since both Realtrax and Fastrack are the same height as tubular track, this should be relatively easy.
