This led Stevenson to bring the rear wheels forward in the 4-2-0 formation, with the cylinders between the leading wheels.

The extra weight of the larger boilers was borne by the leading wheels, making the locomotives unstable, particularly at speed.

The axle or axles of the leading wheels are normally located in a truck (or "bogie").

When this change was carried out the Penn Central fitted its cars with a welded bar pilot to protect the leading wheels from debris impact.

Innovations in steam locomotive design included the introduction of compound engines and bogie rather than axle leading wheels.

The locomotive was being transported along the M5 Motorway when a fire started on the lorry under the loco's leading wheels.

Due to uneven weight distribution the axle load on the leading wheels was 169.7 kN higher than that of the driving wheels.

The two leading axles steered and were of varying track, so that each tyre ran on a clean surface rather than following a rut.

Many of the locomotives were fitted with a speedometer, which was attached to the engineer's side frontmost leading axle.

On these early 2-6-0 locomotives the leading axle was merely used to distribute the weight of the locomotive over a larger number of wheels.

The rear axle was an inside-framed Bissel truck, pivoted ahead of the leading axle.

During their thirty-five years of service they exhibited excellent performance and only minor problems were experienced, such as oval wearing of the leading axle's inside crank.

The K class design used a "Bissel bogie" leading axle and a plain trailing bogie.

They had three cylinders with divided drive: the inside cylinder driving the leading axle, the outside cylinders driving the centre.

Thus boiler capacity could only be increased by making the boiler longer, not wider, bringing the smokebox and cylinders in front of the leading axle.

It had one leading axle and five coupled axles and was one of the most successful designs produced for the Deutsche Reichsbahn.

A single leading axle (known as a pony truck) increases stability somewhat, while a four-wheel leading truck is almost essential for high-speed operation.

They had unusual six-wheeled tenders, with the leading axle mounted in a rigid frame and the other two axles mounted in a bogie.

This locomotive was a 2-2-0 (Whyte notation) type, meaning it had one unpowered leading axle and one powered driving axle.
