In this video we take a look at something unbelievably small… T Gauge.
With a track gauge of just 3mm and a scale of around 1:450, this is the smallest commercially available model railway in the world. But the big question is… does it actually work?
I bought a T Gauge starter set to find out, and in this video I’ll show you exactly what you get, how it runs, and whether it’s a practical option for building a layout. We’ll take a look at the track system, rolling stock, costs, and some of the surprising engineering that makes something this tiny even possible. I’ll also show you how I powered it using a simple DIY controller.
