Why do railway curves feel off-balance? Because they’re meant to.

Cant deficiency is one of the most important—and misunderstood—concepts in railway track design. In this video, I’ll explain why engineers don’t aim for perfect balance on curves, and how cant deficiency helps high-speed and freight trains safely share the same track.

You’ll learn:

What cant deficiency actually is (in plain English)

Why equilibrium cant only works at one speed

How cant deficiency affects bogie behaviour and wheel-rail forces

The benefits (and risks) of designing with cant deficiency

Real-world design trade-offs from the UK and beyond

How tilting trains extend the limits of what’s possible

Whether you're just starting in rail or want a deeper understanding of horizontal alignment principles, this is the breakdown you’ve been looking for.
