I am glad I was able to buy spare DCS remotes and TIUs. As I've stated before on other threads, and not withstanding technological challenges, I believe it is short-sighted decision, and frankly, a bit nervy, on MTH's part to go exclusively towards "Smart" handheld devices to run trains. There's just too many operators, myself included, who are challenged using "swipe" screen applications. Plus, using the DCS remote is fun! It bridges the digital age with analog push-button nostalgia.
Hopefully, Lionel will not pursue a similar path with Legacy, as I also find the Cab I and II's fun to use!
