I once ran some newer tinplate stuff through RealTrax switches, 042 and 054, without trouble. Interestingly, I did have to use a file in some areas for one or two modern engines when the tinplate ran fine. All this said, I realize RT might not be a good choice if your goal is to stay with a tinplate style track to match the trains.
i agree with Marty on Ross. I now use all Ross modern track and switches and love it. If their tinplate is comparable in operation then I'd say it is a safe bet. Perhaps you could ask about purchasing a switch and some track with the ability to return it if it doesn't work well with your stuff.
