Can someone breakdown the differences between all the LionChief systems (LionChief, +, ++, 2.0)? Went on the Lionel site where they reference a chart that I could not find. Have bought 2 different used Lionchief engines for my grandson, since they didn't come with boxes or documentation I have no idea what versions they are. I have to say I think the system is great for kids to the point where I wish kits were available for converting transformer controlled engines. Thanks for any responses.
