In British practice, this is sometimes extended to indicate the type of tank locomotive: T means side tank, PT pannier tank, ST saddle tank, WT well tank. The suffix F indicates a fireless locomotive F. Note that this locomotive has no tender. Other suffixes have been used at times, including ng for narrow-gauge locomotives i. In Britain, small diesel and petrol locomotives are usually classified in the same way as steam locomotives, e.

This may be followed by D for diesel or P for petrol, and another letter describing the transmission: E for electric, H hydraulic, M mechanical. Thus DE denotes a six-wheel diesel locomotive with electric transmission. 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.

Thus 4wPE indicates a four-wheel petrol locomotive with electric transmission. For large diesel locomotives the UIC classification is used. The main limitation of the Whyte Notation in classifying locomotives was that it did not cover non-standard steam locomotive typessuch as Shay locomotives , which use geared trucks rather than driving wheels.

This led to the design of other forms of classification. The most commonly used system in Europe outside the United Kingdom is the UIC classification scheme, based on German practice, which can more completely define the exact layout of a locomotive. In American and to a lesser extent British working practice, most wheel arrangements in common use were given individual names, often from the name of the first such locomotive built.

For example the type arrangement is named Planet , after the locomotive on which it was first used. This naming convention is similar to the naming of warship classes. Here is a list of the most common wheel arrangements: in the illustration the front of the locomotive is to the left. Wikimedia Foundation.

The first number was always the leading wheels and the last number was always the trailing numbers. The numbers in the center were the driving wheels, which moved the locomotive. A notation that contains 4 or 5 numbers is a Mallet articulated locomotive. A few wheel arrangements can't be covered by the Whyte notation.

This includes a Turkish arrangement that started out as a But when a pair of carrying wheels were added to the design, between the central and rear driving axles to fix an axle load issue, it cannot be explained using the Whyte notation. Some steam locomotives, although rare, don't rest their driving wheels on the rails. This is also impossible to explain using the Whyte notation.

The driving wheels rest atop other wheels.
