How are locomotive wheels numbered?

In this system numbers are assigned to the leading, driving, and trailing wheels of the locomotive. The first number is the number of leading wheels. The middle number (or numbers) give the number and arrangement of drivers. The last is the number of trailing wheels (typically under the firebox).

What are the wheels on a steam train called?

The leading wheel or leading axle or pilot wheel of a steam locomotive is an unpowered wheel or axle located in front of the driving wheels. The axle or axles of the leading wheels are normally located on a leading truck.

What are the seven 7 components of the steam engine?

What are the seven 7 components of the steam engine?

Tender. Attached rail vehicle that holds both water for the boiler and fuel such as wood, coal, or oil.
Cab (US+ and UK+) Footplate (UK+)
Whistle.
Reach rod.
Safety valve.
Generator / Turbo-generator.
Sand dome.
Throttle lever (US+)

Which type of mechanism is found on the wheels of a steam locomotive?

When heated, water turns to an invisible vapor known as steam. The volume of water expands as it turns to steam inside the boiler, creating a high pressure. The expansion of steam pushes the pistons that connect to the driving wheels that operate the locomotive.

What is Bo-Bo wheel arrangement?

Bo-Bo is the UIC indication of a wheel arrangement for railway vehicles with four axles in two individual bogies, all driven by their own traction motors. It is a common wheel arrangement for modern electric and diesel-electric locomotives, as well as power cars in electric multiple units.

What is Bo-Bo and Co?

The letter or number refers to the number of axles in a single frame, for example: A locomotive with two bogies (diagram right), each bogie having two axles is a Bo-Bo or a B-B. The same problem has appeared in the US where the Bo-Bo or Co-Co arrangement is common but they are widely referred to as B-Bs or C-Cs.

What are the parts of a steam train?

Why are train wheels called bogies?

The name is derived from the German railway engineer Wilhelm Jakobs (1858–1942). Versions of it are used on both freight and passenger vehicles.

What are the main parts of a steam engine?

Crudely speaking, there are four different parts in a steam engine:

A fire where the coal burns.
A boiler full of water that the fire heats up to make steam.
A cylinder and piston, rather like a bicycle pump but much bigger.
A machine attached to the piston.

What are the basic parts of a steam engine?

The basic parts of the steam engine in a locomotive would be a boiler, slide valve, cylinder, steam reservoir, piston, and a drive wheel. In the boiler, there would be a firebox where coal would be shoveled into.

What turns the wheels on a locomotive?

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.

What are locomotive wheels made of?

The wheels will be made out of steel, and they are made out of steel for a few reasons. First, did you know that road vehicles lose a ton of energy just by pushing its tires down the road? Tires made out of rubber bend and they wear out relatively quickly.

What are the components of a steam locomotive?

Steam locomotive nomenclature is a listing of the components found on a Steam Locomotive . The following components appear on the illustrations shown above. Boiler — A water container that is brought to a boil by hot gases passed through long tubes, thereby producing steam. From time to time the tubes need to be cleaned as they accumulate soot.

How is the wheel arrangement of a diesel locomotive classified?

The wheel arrangement of small diesel and petrol locomotives can be classified using the same notation as steam locomotives, e.g. 0-4-0, 0-6-0, 0-8-0. Where the axles are coupled by chains or shafts (rather than side rods) or are individually driven, the terms 4w, 6w or 8w are generally used.

How is Whyte notation used in steam locomotive classification?

Whyte notation. The notation counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, numbers being separated by dashes. Other classification schemes, like UIC classification and the French, Turkish and Swiss systems for steam locomotives, count axles rather than wheels.

What was the name of the wheels on a steam locomotive?

Drivers1 — The wheels that deliver locomotive power to the rails. The drivers are weighted so that the center of gravity of the drivers and rods coincides with the center of rotation. Main rod — A steel arm that converts the horizontal motion of the piston into a rotation motion of the Driver. Also called the connecting rod.
