Having not kept current with all this wifi and the several Lionel 'Lionchief' systems, it certainly can be confusing to many of us out here. Our club has 6 or 7 Lionchief engines but no wifi as yet. From this discussion above, the Lionel system appears to be complex in trying to figure what runs with what.
Is the MTH wifi still 'better' in that it will operate Legacy easily if I remember correctly?
