Why are Network Rail cutting down trees?
Leaves falling from trees onto the railway reduce trains’ grip and cause disruption to services, and a single tree can have as many as 50,000 leaves. This all adds up, and it’s one of the reasons we carry out vegetation management.
How do trains cross tracks?
Unless the switch is locked, a train coming from either of the converging directs will pass through the points onto the narrow end, regardless of the position of the points, as the vehicle’s wheels will force the points to move. Passage through a switch in this direction is known as a trailing-point movement.
How do trains keep on track?
The wheels on each side of a train car are connected with a metal rod called an axle. This axle keeps the two train wheels moving together, both turning at the same speed when the train is moving. This is where the wheels’ geometry comes in. To help the wheels stay on the track their shape is usually slightly conical.

How are the wheels on a train different?
Train wheels aren’t perfect cylinders. They’re beveled to make them wider on the inside. This means that when the train shifts left or right on the track, the diameter of the wheels can change. But because the wheels are connected by an axle, they still spin at the same rate.
What makes a train stay on the tracks?
The wheels that have to travel a greater distance have a greater diameter, and everything stays aligned. The end result is a train that stays on the tracks. This content is created and maintained by a third party, and imported onto this page to help users provide their email addresses.
Why does a train always turn at the same speed?
Trains typically have wheels that are connected together by a fixed axle, meaning that the wheels on both sides of the train always turn at the same speed. This can present problems when turning, because one wheel has to cover more distance than the other.
