Easy Control for Märklin CS2 and CS3
RailControl Pro is an easy-to-use app for controlling your model train layout with your iPhone or iPad.
Connect
With RailControl Pro it’s easier than ever to connect Märklin Central Station 2 or Central Station 3 to your iPhone or iPad.
Control Locomotives
Control speed, driving direction and the functions of your locomotives with just a touch, click, keystroke, or even a game controller.
Control Articles
Turnouts, signals, turntables and other accessories, can be controlled in the Track Diagram or Articles overview.
Control Events
Events can now be started straight from RailControl Pro as well.
Real Multi Window
Juggle with windows on iPad. Be it to host your favorite locs next to each other, or just to keep the track diagram within reach. Feeling brave? RailControl Pro also supports Stage Manager.
Dark Mode
RailControl Pro aims to blend in. Controlling your trains in a dark room, or outside in the sun? We have your back!
Keyboard Shortcuts
Pros use keyboard shortcuts. That's why RailControl Pro has them. Controlling locs with a keyboard turns out to be great.
Game Controllers
Connect up to four game controllers to your iPhone or iPad and hand it over to other people for even more fun!
Free Trial
Try RailControl Pro one week for free with the trial. After the trial period, RailControl Pro requires a yearly subscription to work.
