๐Ÿš‚ How does an automated model railway know where a train is?

That question became one of the biggest challenges during the build of Holgate's automation system.

Over the build we tested several different approaches, including:

๐Ÿ”น RailCom
๐Ÿ”น Hall Effect sensors
๐Ÿ”น Infrared detection
๐Ÿ”น Current detection

Each solution had strengths, but also practical limitations when operating a busy club exhibition layout with locomotives owned by multiple members.

In our latest Holgate article, we explain the testing process, what worked, what didn't, and why current detection ultimately became the solution that allowed DCC-EX and EX-RAIL to safely manage train movements around the layout.

It's a fascinating look behind the scenes at the real-world engineering decisions that helped shape Holgate's automation system.

Have you used train detection on your own layout? We'd love to hear what worked for you.


How Holgate tested RailCom, Hall Effect sensors, infrared detectors and current detection to solve train location detection for DCC-EX and EX-RAIL automation.

Many modellers are interested in DCC-EX but aren't ready to convert their entire locomotive fleet to DCC.

A question we are often asked is:

โ“ Can I run my existing DC locomotives with DCC-EX?

The answer is yes.

DCC-EX can operate conventional DC locomotives using PWM control, allowing you to continue using the locomotives you already own while benefiting from modern wireless throttles, accessory control and future expansion options.

In our latest article we look at:

๐Ÿš‚ Running DC locomotives with DCC-EX
๐Ÿ“ฑ Wireless control using phones and tablets
๐Ÿ”€ Point motors, signals and accessories
๐Ÿ”„ Moving from DC to DCC at your own pace

Are you still running DC, fully DCC, or somewhere in between? Let us know in the comments.

Can DCC-EX run DC locomotives? Learn how DCC-EX uses PWM control for conventional DC trains, plus wireless throttles, accessory control and a simple upgrade path to DCC.
