Computer-controlled model railway UK · practical setup guide
Computer-controlled model railway in the UK.
From first connection to safe automation.
A computer-controlled model railway needs control software, a compatible digital command station and a proven local connection. LocoLink brings the throttle, points, signals, track diagram, feedback, decoder tools and staged automation together on Windows, Mac, iPhone and iPad.

The complete control path
Six parts that must work together
Computer control is reliable only when the software, digital system and physical railway are tested as one chain.
Digital command station
The command station and booster still create the track signal and provide the physical connection to decoders.
Supported local connection
Use the exact network, USB, serial, interface or gateway route documented for the chosen system.
Track diagram
Represent track, points, signals, feedback and routes in the same visual space used for operation.
Feedback and blocks
Prove each detector and stopping section before it is allowed to influence automatic movements.
Manual fallback and stop
Keep emergency stop obvious and retain dependable manual control while automation is commissioned.
Commissioning sequence
Build computer control in three testable stages
Each stage has a clear pass condition. Do not move the complete railway before the small test path works.
Connect and prove one locomotive
Select the exact command-station profile, connect locally and test emergency stop, direction and one decoder function at low speed.
Add one point and one feedback input
Verify the accessory address, visible indication and detector state before drawing the complete track diagram.
Commission one guarded route
Measure stopping behaviour, validate block transitions and only then expand to shuttle services, timetables or automatic running.
System roles
What every part of a computer-controlled railway does
Confusing these roles leads to vague compatibility claims and difficult fault-finding.
| Part | Primary job | Pass check |
|---|---|---|
| LocoLink | Operator interface, project, track diagram, decoder workflow and automation logic | The requested action is clear and reaches the correct object |
| Command station | Translate software commands into the railway protocol | Stable connection and correct response for the exact firmware |
| Booster and track power | Supply the digital track signal and power | Reliable operation without unexplained cut-outs |
| Locomotive/accessory decoder | Act on its address and configured functions | Correct direction, functions and accessory position |
| Feedback module | Report occupancy or sensor events | Every input changes once, on the expected section |
| Routes and blocks | Coordinate safe movements through the track plan | Conflict, occupancy and stop behaviour are validated |
Compatibility reviewed . Use the LocoLink compatibility adviser for the exact fully supported connection route. “DCC” by itself does not identify the computer interface.

Practical engineering
How to control a model railway with a computer
The computer is not connected directly to every locomotive. LocoLink sends an action through a supported local connection to the command station. The command station and booster create the digital track signal, and the addressed decoder carries out the command. Feedback travels in the other direction so the software can understand occupancy and events.
Start with a deliberately small path. A locomotive must stop, change direction and trigger one known function. One point must move to the requested position. One feedback input must appear on the correct section. This makes faults attributable before a full roster or track diagram adds complexity.
Automation is the last layer, not the first
A computer-controlled model railway can remain completely manual. Add blocks and automatic routes only when addresses, feedback and stopping distances are repeatable. Preserve the existing project, keep an emergency-stop path available and test exhibition or club operation on the real hardware before relying on it.
LocoLink is the software in this workflow; Z21, ECoS, DCC-EX, NCE and Märklin CS3 are examples of supported digital systems. The product is always called LocoLink.

FAQ
Frequently asked questions
What is a computer-controlled model railway?
It is a real model railway where software communicates with a compatible digital command station to drive locomotives, operate points and signals, show a track diagram, process feedback and optionally automate routes.
Does the computer replace the command station?
No. The command station and booster still create the track signal and connect physically to the railway. LocoLink provides the operator interface, project and control logic.
Can I control a model railway from a phone or tablet?
Yes. LocoLink runs on iPhone and iPad for handheld control, while Windows and Mac provide a larger control-room view.
Do I need feedback for computer control?
Not for manual driving and point control. Reliable block automation normally needs correctly configured occupancy or event feedback.
Which command stations can LocoLink use?
Every digital system listed in the LocoLink compatibility adviser is fully supported. The adviser identifies the exact direct, interface or gateway connection route.
Can manual and automatic trains operate together?
Yes when feedback, blocks, routes and priorities are configured and tested for that operating plan. Commission one route before expanding mixed operation.
Does LocoLink need the internet to drive trains?
The control path to the command station is local. Downloads, licensing or optional platform services may use the internet separately.
How should I test a club or exhibition railway?
Keep the current working setup and backup, test LocoLink in parallel, verify emergency stop and every critical route on the actual hardware, and retain a manual fallback.
