The definitive wireless controller for your Märklin Central Station 2 or 3. Take full command of your model railway from anywhere on your local network — no adapter, no laptop, no fuss.

Central Station brings the CS3's own layout, roster and automation into a fluid, native app across iPhone, iPad, Mac and Apple TV. Everything you can do from the CS3 itself, done faster — and now your track plan is reproduced exactly as the Central Station draws it, ready to share with anyone.

Everything you need. Nothing you don't.

◐

Locomotive control

Circular speed gauge, one-tap stop, direction toggle, and a 24-function grid with Märklin-standard icons for lights, sound, horn, smoke and pantograph.

▧

Pixel-accurate CS3 layout

Not an approximation — your track diagram is reproduced exactly, using the same connection geometry, curve maths and switch artwork the Central Station draws itself. Turntables come complete with all 48 numbered stalls. Tap any accessory to throw it.

◈

Digital turntable

48-position dial with target picker and left/right incremental controls. Detected automatically when a turntable article is present in your layout.

▶

Live webcam

Plug a USB webcam straight into your CS3 and Central Station finds it on its own — no setup, no URL to type. Any IP camera works too, with MJPEG streams and JPEG snapshots both supported.

⇄

Share your layout

Export a track plan as a single file and send it by AirDrop, Mail or Messages. Open one someone sends you and it lands straight in your list — never overwriting a layout you already have.

◉

Game controllers

Connect up to four PlayStation, Xbox or MFi controllers. Thumbstick = speed. Buttons = direction, lights, functions. Perfect for family operating sessions.

▤

Multi-loco view

Drive 2 or 4 locomotives side-by-side on iPad or Mac. Full column view with independent speed, direction and function controls for each.

↻

Real-time sync

Live state sync with the CS3 every 2 seconds — see speeds, directions and function toggles change from any hand controller in real time.

◆

Routes & automation

Build named sequences of switch, signal, speed and delay commands. Trigger routes on feedback contacts. Monitor CS3 automation state live.

Built for hobbyists, not tourists

Automatic CS discovery — UDP broadcast plus HTTP subnet scan finds your Central Station in under two seconds.
Full roster import — reads lokomotive.cs2 directly, including custom accessories, function types and MFX UIDs.
CS3 backup management — list, download and create backups without opening the CS3 web UI.
Layout files — export any track plan as a .cslayout document. Keep it as a backup, or send it to another modeller and let them open it with a tap.
Hand-thrown turnouts drawn correctly — manually operated points render in the Central Station's own grey, distinct from decoder-driven ones.
Favourites & smart collections — filter your roster by name, favourite, or collection tag.
Keyboard shortcuts — arrow keys for speed, D for direction, L for lights, 1–9 for functions.
Statistics — paths completed and operating hours per locomotive, with charts.
Split View, Stage Manager, multiple windows — first-class multi-window support on iPad and Mac.
No account. No tracking. No subscription.

How it works

Central Station talks to your CS2 or CS3 over your local network — UDP CAN on ports 15730 and 15731 for commands, and HTTP on port 80 to read your layout and roster. It does not touch the cloud.

Requires a Märklin Central Station 2 or a CS3 running firmware 2.6 or later, and an iPhone, iPad, Mac or Apple TV on the same Wi-Fi network.
