Our mission

We do not have a manual.

That is not a missing feature. That is the standard.

We believe the UI should explain itself. The next step appears when it matters, feedback is visible immediately and beginners can start without reading paperwork first.

See what mattersButtons, status and warnings make the current state obvious. Act without searchingSetup, connection and driving stay close to the place where you are working. Grow without stressAdvanced options appear only when your layout asks for them.

Migration · Pro

Switching from another app?
Bring your layout along.

Already invested years in another model-train control program? You don't have to start from scratch. LocoLink imports your locomotives, addresses, function mappings and (where supported) your switchboard structure in seconds — so you can pick up exactly where you left off.

  • ✓Locomotives + DCC addresses — names, addresses, F0–F31 function labels and preset mappings stay preserved.
  • ✓Switchboard layouts — turnouts, signals and section blocks come across as editable elements (Pro).
  • ✓Side-by-side preview — review every imported item before it lands in your library, no surprise overrides.
  • ✓Works alongside your old setup — LocoLink doesn't touch the source files, so you can run both apps until you're ready.

New: smart product database

Layout building

  • Switchboard editor with blocks, routes and signals
  • Turntables, crossings, lights, relays and sounds
  • Stations, trains, wagons and car traffic tools
  • Project library, thumbnails and quick project switcher

Automation & feedback

  • Automatic driving, shuttle service and route strategies

Serious layout support

The details advanced operators ask for are already built in.

LocoLink is designed for real club rooms and growing home layouts: NCE and major command stations, multiple throttles, editable decoder presets, Dutch signal output reservation, Dynamo/RMC783 and G-scale booster monitoring in one clean workflow.

NCEready for popular North Coast Engineering layouts F23/F24ditch-light presets with horn-triggered crossing logic

Multiple command stations

Use several NCE, Z21, ECoS, CS3 or DCC-EX stations in one workspace. No per-station add-on or hidden upgrade.

Decoder presets

Save reusable decoder setups for function keys, horn triggers and lighting behavior. Start from a preset, then tune every decoder by hand.

Dutch signals done right

NS main, combination and advance signals reserve 3 static DCC outputs: red, green and yellow, with automatic aspect mapping.

Dynamo / Dinamo RMC783

Listed in the setup wizard with bridge-ready support for clubs and layouts that use Dinamo hardware.

G-scale & boosters

Scale-aware booster presets up to 10A / 24V for G-scale, with live voltage, current and temperature monitoring.

macOS Experience

Your layout, your workspace.

Arrange multiple windows across your displays. Locomotive list, driver's cab, switchboard, turnouts — all open simultaneously, exactly where you want them.
