Many of the abbreviations/terms used in the Bus and Model world can be very confusing, what do they mean? e.g. AEC, BMMO, etc. I am frequently contacted by people asking the answers. To assist everybody I have decided to compile this "Glossary" page. Have you ever heard or seen abbreviations or terms that have confused you in the past? If they have confused you then they undoubtedly will have confused others.

Please CLICK HERE to email and help me expand this list  with any abbreviations and terms together with their meaning, that you think would assist others. Please also email with items you would like to see the answers to. I look forward to hearing from you.

Whilst compiling this list I have become aware that with some abbreviations particularly those relating to London vehicles there are "official" abbreviations and also "common use" abbreviations. Where I receive more than one alternative I will show both.

Body Classifications




Model Bus



I am very grateful to Terry Stapley from the PSV Circle for providing me with the information for this section. 

These lists contain the "official" PSV Circle body classification codes which have been adopted for general use in the Industry and transport press. I understand British Bus Publishing adopted their own system of codes a couple of years or so ago.

There are two types of Body classifications i.e. Letters before seating capacity and letters after seating capacity. These are listed separately below.

The seating capacity of a double deck vehicle is expressed as a fraction with the number of seats in the upper saloon 'over' the number of seats in the lower saloon - for example 41/32 indicates a vehicle having 41 seats on the upper deck and 32 seats on the lower deck.

Note: The definition of 'highbridge' and 'lowbridge' refer to the body layout and not the overall height of the vehicle (that is 'lowbridge' has a sunken gangway on the upper deck or part thereof).
