What Do You Need to Get Started with DCC-EX? (Beginner Guide)
What do I need to start a DCC model railway?
At its simplest, a DCC model railway needs a DCC command station, a suitable power supply, a way of controlling the trains, and locomotives fitted with DCC decoders.
The command station sends digital instructions through the track to each locomotive decoder, allowing individual trains to be controlled independently. Your throttle provides the controls you use to select a locomotive, change its speed and direction, and operate functions such as lights and sound.
How those components are provided depends on the DCC system you choose. Some systems combine several of them into one package, while others allow the individual components to be selected separately.
If you are considering DCC-EX, there are two main ways to get started: use a ready-to-run command station, or build and configure your own system.
What do you need to get started with DCC-EX?
A DCC-EX system follows the same basic principle. You need a command station to generate the DCC signal, a suitable power supply, and a throttle or other control interface.
DCC-EX gives you a choice between building and configuring the system yourself or using a ready-built command station.

Looking for the simplest route into DCC-EX?
The CSB1 Ready-to-Run Command Station
combines the command station, display and built-in Wi-Fi control in a ready-built unit.
A suitable power supply can be selected with the system if required.
There are two ways to set up DCC-EX
| Option | Best suited to |
|---|---|
| Ready-to-Run system | Users who want a ready-built command station with minimal assembly and configuration |
| Builder Edition / DIY setup | Users who want greater control over components, installation and expansion |
Option 1: Ready-to-Run system
The CSB1 Ready-to-Run Command Station provides a straightforward way to start using DCC-EX without having to assemble the command station yourself.
- Ready-built DCC-EX command station
- Built-in display
- Built-in Wi-Fi control
- USB-C connectivity
- Power supply available as an option
Once connected to your layout and a suitable power supply, you can control trains using a compatible phone, tablet or wireless throttle.
If you are new to DCC-EX and would rather concentrate on running trains than building the electronics, the Ready-to-Run Command Station provides a ready-built starting point.
Option 2: Builder Edition / DIY setup
A Builder Edition or DIY setup gives you greater flexibility over how your DCC-EX system is installed and configured.
- Board-only command station
- Choose your own power supply
- Choose your display and enclosure
- Flexible installation and expansion options
This approach can suit experienced modellers, custom installations, clubs, or anyone who enjoys building and configuring their own model railway electronics.
It requires additional components, wiring and configuration compared with the Ready-to-Run version.

The essentials for a DCC-EX setup
Every DCC-EX system needs three main components:
- Command station – generates the DCC signal and sends commands to your railway
- Controller or throttle – lets you select locomotives and control speed, direction and functions
- Power supply – provides the power required by the command station and railway
Your locomotives will also need suitable DCC decoders to receive and respond to the commands sent through the track.
With a Wi-Fi capable DCC-EX command station, the throttle can be a compatible phone or tablet, browser-based throttle, or dedicated physical wireless throttle.
Power supply requirements
The power supply you need depends on your command station, scale and layout requirements.
- The CSB1 Ready-to-Run Command Station can be purchased with a suitable power supply or without one if you already have an appropriate supply
- Builder Edition and DIY installations require you to provide a suitable power supply for your chosen configuration
For many CSB1 installations, a 15V 5A power supply provides a convenient ready-to-use option.
The appropriate voltage and current capacity should always be chosen for the scale, locomotives and equipment being used on the railway.
Can I expand my DCC-EX system later?
Yes. You do not need to build a fully automated railway from the beginning. You can start with locomotive control and add other capabilities as your layout develops.
- EX8874 motor shield – adds additional track output channels
- PCA9685 servo controller – provides servo control for applications such as turnouts and signals
- Sensors and automation – can be added as your layout and control requirements develop
DCC-EX can therefore start as a straightforward way of controlling trains and expand later to include turnouts, routes, sensors and layout automation.
Summary
If you're starting a DCC model railway, you need a command station, suitable power, a way of controlling your trains, and DCC decoders fitted to the locomotives.
With DCC-EX, you can choose whether to build and configure the command station yourself or use a ready-built solution.
