Gaugemaster Infinity Digital:
Wireless DCC Model Railway Control System
With Infinity Digital, Gaugemaster has rewritten the rulebook on what design engineers think a digital system should be, and built one that does everything a modeller wants from a modern digital model railway control system. Proudly designed, engineered, and manufactured in the UK, the Gaugemaster Infinity Digital range represents the next generation of digital model railway control; intuitive, expandable, and built for the way real modellers operate.
With the Gaugemaster Infinity Digital System, wireless Bluetooth® control with a 3.3-amp power supply straight out of the box is standard; there’s no longer any need to deliberate between wired and wireless operation. The supplied wireless remote handset gives you up to 50 metres of freedom around your layout – and that’s just one of many cutting-edge features that set the Infinity system apart. Its customisable settings allow you to run your layout exactly how you want, with precise, effortless control through a wireless DCC control system over every digital locomotive and accessory.
For those with larger layouts, the Infinity Digital Plus is the go-to system. This model railway controller offers all the benefits and features of the standard unit, but also boasts a larger 6-amp supply, making it suitable for O scale layouts. G Scale modellers haven’t been forgotten either, with the Infinity Digital G controller designed with the higher 6-amp supply and 20v output, ideal for most G Scale layouts.
Of course, the Infinity system is fully NMRA compatible, supporting 68 light and sound functions, with all 68 function buttons fully customisable as toggle or momentary actions, and a stored library of up to 100 locomotives and 100 accessories, all with the innovative “Share” feature, which allows information to be set up on one handset and shared with the next for flexible operation. For more information on functions, compatibility and system setup, visit the Infinity Digital FAQs.
Additional innovations include the Yard/Drive mode, Animation Sequence feature, Scale Clock/Speed display, and even an optional Locomotive Fuel Tank simulation. One feature that truly redefines digital control is the new Multiple Working Consist function. Forget complicated setups; this system makes double-heading effortless and uniquely allows complete sound function control for each locomotive within the consist.
Getting Started with Gaugemaster Infinity Digital
Getting started with Gaugemaster Infinity Digital is easy. We have curated three starter packs tailored to your specific needs. Our Starter packs contain everything you need to power your Digital layout. Don't forget that your locomotives will need decoders to be fitted to operate on any digital system.
Within each starter set, you will find a Digital Remote Controller, a Base Unit, and all the necessary cables, transformer, and accessories to get the system up and running. Connect the controller to your layout with a suitable wire, and you will be in control in moments.

Expanding Infinity Digital
Taking control of your layout is easy with Gaugemaster Infinity Digital, as it can grow to suit your needs. Updateable and expandable, the Infinity Digital Base Units can connect up to two Digital Remote Handsets, enabling instant control with a second controller. If you need more power, an Infinity Digital expansion module provides an additional 14 volts, 3.3-amp power district, and the Infinity Digital Plus expansion offers a 14 volts, 6-amp power district, with both expansions allowing you to add two more remote handsets to the environment. G scale users can also expand with the Gaugemaster Infinity Digital G expansion, which enables an additional 6-amp district with the higher 20-volt output. If you already have all the power you need and only want additional operators, the Wireless Handset Receiver Unit is your go-to option, allowing you to connect two more handsets to any Infinity Digital system.
The best bit about expanding Infinity Digital? You can control anything from N to G Scale, all from one handset! Each system and expansion can be connected with an Infinity Lead Set (available separately and as part of an expansion unit), allowing one or more handsets to control multiple base units at the same time, whether that be the Digital, Digital Plus, or Digital G, giving you full control of all your layouts. This works for the additional expansion modules too, all designed to operate seamlessly within your Infinity Digital environment.


In addition to controlling all locomotives and expanding the system with the Gaugemaster Infinity Digital Expansion modules, the range also includes modules for controlling other areas of a layout. The Infinity Digital Switch Accessory Decoder is the ideal interface between point motors and your Infinity system, allowing you to make full use of accessory control and accessory sequencing, and the Infinity Digital Reverse Loop Module takes care of all those polarity issues that come with reverse loops, triangles and turntables.
