How the licence reaches you
Online through your Lokstore account (14 days of grace without a connection), bound to one computer, or as a file. You sign in with a short code on the portal – you never type your password into the software. If a licence runs out, operation carries on; only nothing new can be started.
All prices incl. VAT · Pre-order: you pay now and receive your licence by e-mail at launch, expected on 15 November 2026.
Try before you buy: once per Lokstore account you can unlock a free test licence yourself in LoDi-Aura.
The train drives itself – and stops to the centimetre.
Drag the train onto its destination track. LoDi-Aura sets the route, pulls away gently, keeps to speed limits and stops right on the mark.
- The loco learns itself. On every run through a block LoDi-Aura measures the real speed – no tables to maintain.
- Braking by physics. The braking distance is calculated; a heavy freight train brakes earlier.
- Sequences without code. Departure whistle, shunting move, lights by the clock – put together from building blocks.
Draw it, set it up, drive it – in one program.
Lay track, assign blocks and detectors – and run trains on it straight away.
- The full kit. Turnouts, slips, turntable, traverser, signals – everything a layout has.
- Start without hardware. The simulation runs your plan before any device is connected.
- Find mistakes early. One click checks the plan and names every mistake in plain words.
Manage, drive and program your locos.
Loco profile, throttle with function keys, CV programming and the online loco database in one place.
- Read and write decoders. Via RailCom, main track or programming track – mfx included.
- Multiple traction. Several locos in one train run at the same speed.
- Maintenance in view. Running hours and kilometres are counted.
Your LoDi devices find themselves.
Rektor, S88- and Shift-Commander are found on the network, firmware updates run from the program. LoDi devices never need a licence.
- Your command station can stay. Bring in a Märklin CS2/3, ESU ECoS, Z21 or Lenz station with a command-station licence.
- On the tablet too. Further computers and tablets on the home network drive along – with roles and rights.
- Online backup. Every state of your layout kept in your Lokstore account if you like.

Frequently asked questions
Do I need LoDi hardware?
Not to try it – the simulation runs without devices. For real operation you need a command station: a LoDi-Rektor (no licence needed) or your Märklin CS2/3, ESU ECoS, Z21 or Lenz station with a command-station licence.
Can I keep my current command station?
Yes. Bring in any third-party station with a command-station licence for €49 – or all of them with Professional.
