Colin & David Johnson

The Railway Gauging Experts

Founded as a family business in 2008. David brought his 30 years in the railway industry, his proven experience in gauging technology and a passion for developing software. Colin brought his diverse engineering experience from aerospace and motorsport, and his desire for things to be presented clearly.

D/Gauge set out to answer one question. Why doesn’t the train fit? The solution has typically been to make the train smaller, or move the infrastructure entirely. Both an extreme and costly response, one they aim to avoid.

D/Gauge challenge every aspect of gauging by going back to first principles. That’s been their focus ever since. They have led cutting-edge research, created smarter, deeper datasets and invested in a new software fit for the future.
