Imagine having control over your model railroad from any iOS phone or tablet. How much more convenient would operating your model railroad be with the same device you use throughout your daily life? The large, bright full-color screens found on today's smart phones and tablets are perfect for accessing the DCS features found inside your Proto-Sound 2.0 and 3.0 locomotives. Better yet, the expanded range and speed of wifi would ensure that your trains respond to DCS commands faster and more reliably than ever before.

When paired with M.T.H.'s DCS App and our new DCS WiFi Module, you no longer have to imagine controlling your model railroad with your phone, you can!

The DCS WiFi Module plugs into any DCS Track Interface Unit (TIU) and provides the user with wifi control over the layout when used with the M.T.H. DCS Mobile App. Setup is simple and quick and the module can be configured as a stand alone unit or easily combined into an existing wifi network.

What’s New

Version 3.2.1

Added iOS 9 support, corrected issues with the engine control direction buttons and Lionel TMCC engines, and added a link to the MTH privacy policy on App Settings.

I am running both Lionel & MTH Locos with this Premium APP

I am using the Premium APP on an iPhone 7 Plus. It is easy to program the APP to run Lionel & MTH Locos. Just follow the easy to follow prompts. I am operating over twenty locos with this APP on four main lines and from sidings. The soft keys are a lot better over the old hand held controller because each soft key has a description of what it does.

I would highly recommend this MTH DCS Wi-Fi APP for your layout. Start with the free APP and when you are ready purchase the Premium APP and you will have fun running your trains and so will visitors to your train room / layout.

Wonderful app. Nothing is perfect, but ALL MTH functions flawlessly. Most of Lionel command engines also do well. Why complain? If you are stuck on Legacy equipment, then use Lionel’s programming.
I am having so much fun running my system on an iPad. Great interface. Good response. Full features.
If you want to have great control, and a heck of a lot of fun, take the plunge. As a former Lionel postwar collector and MTH concert, quit complaining. If it doesn’t meet your expectations, then either you are doing something wrong or you need to get a component replaced.
Well done, MTH. Period.

Should be Free! Shame on MTH!

I love being able to control my model trains from the MTH DCS App. But the fact that we're being charged $20 to unlock all the features in the app when we've already paid close to $200 for the Wi-Fi DCS module is unacceptable! It took an entire year for this app to catch up to having most of the features that the remote control has. The app should be completely free and shame on MTH for ripping off its loyal customers.
