About this app

Control you entire model railroad from most Android phones or tablets in this simple to use yet feature rich app! The M.T.H. Digital Command System (DCS) is the most comprehensive and innovative model train control system available. While, at the same time, the easiest to set up and use! You’ll be running your trains in just a few minutes after installing the Wi-Fi DCS app and connecting to any one of several M.T.H. DCS track interface units.

The DCS system is capable of running conventional AC or DC powered model trains utilizing track power controls as well as the ultimate experience of full featured MTH ProtoSound 2.0 or 3.0 and Atlas O® ProtoSound 3.0 locomotives. In addition, DCS is the only cross-platform model railroad control system. When cabled to a Lionel® command base DCS also runs TMCC® and Legacy® engines all within the same app, on the same track, at the same time!! No other system has this capability.

The DCS app connects directly with our entry level system, the DCS Explorer for those just starting their journey into model railroading. For more advanced users, the DCS Wi-Fi Interface Unit (WIU) in combination with the Track Interface Unit (TIU) or, the all new Wi-Fi Track Interface Unit (WTIU) opens up the vast array of features available within the world of DCS. Run multiple trains simultaneously on the same track, control switches and accessories, and immerse yourself in the depth of sound and control features that is Wi-Fi DCS.

Simply the best way to run YOUR railroad!!

Ratings and reviews

this app is Buggy!! Took forever to get it to connect. had to enter my wifi ssid and password manually into LuCi. Router would not connect automatically but even now the app is buggy. stalling and freezing occasionally. Having to restart the app, works sometimes. Sometimes works fine for a bit then crashes. Sure hope they are working on fixing it , because when it works, it's very cool.

I bought a WTIU specifically to run all my newer Protosound 2 and 3 engines since MTH's other technology is abandoned and expensive. The phone recognizes the WTIU is connected via it's own wifi. But when I open up the app, the app says "No WTIU found." Then, I try the home setup with ethernet cable via the online instructions. The same thing happens. No matter what configuration I use, the app DOES NOT, WILL NOT, CANNOT recognize the WTIU despite what my devices say. This app is garbage.

My engine screen is frozen and won't let me select any of the buttons, same thing with my track screen, but the track screen is the bell, whistle, throttle screen? I'm so confused as to what the heck is going on. I just set up my WTIU according to the instructions and I just downloaded the app. WTIU has had a successful firmware upgrade and still the screens are frozen. Not all of them though. Just the important ones. Can't add any locomotive. Please help. I'm using an android.
