Naming Conventions for Fleet Lists

This page sets out the rules I like to follow when compiling fleet lists, and will help to give you an understanding of how to read them.

As a general rule, I try to avoid abbreviations and codes, as there is plenty of room on the page for all of the details. The exception to this rule is the seating layouts, which follow the pattern given in the fleet news section of 'Buses' magazine.

I do not use any of the abbreviations used by the PSV Circle for chassis and body types, as I find these very vague and a little confusing.

Some fleet lists may also be incomplete. This could be due to a lack of information, or I have simply not uploaded the list yet. I will indicate this where possible. The data provided many very, depending on the level of detail available on the source information.

Fleet Numbers and Registrations

If fleet numbers are used on a fleet, then this column will be present. Vehicles will be displayed in numberical/alpha-numerical order. If fleet numbers are not given, vehicles will be listed in registration order, with the oldest vehicles at the top and the newest vehicles at the bottom.

Chassis Types

The chassis type is given in the following pattern: Manufacturer, Model Name, Model Designation (e.g. Optare, Solo, M850). In the fleet lists these are separated by spaces only, the commas here are for illustration purposes.


The term integral refers to both buses designed and built as a single unit, and buses which comprise a separate chassis and body but both components are produced by the same manufacturer.

The only exception is where a manufacturer offered two different body styles on the same chassis. An example of this is the Transbus Trident, which was available with either a Transbus President or Transbus ALX400 body. In such occasions, the word integral will not be used, with the bus having a separate chassis and body description


'Fleet' refers to vehicles painted in the main livery for an operator. Other liveries for specific services will have a description added, such as 'Megabus'. Vehicles pending repaint into fleet livery may have a description representing their colour, such as 'allover red' or 'red & blue with fleet names'.

Seating Layouts

B Single Deck Bus
H Double-Deck Bus
L Lowbridge Double-Deck Buse (rare)
C Coach
F Front Entrance
D Dual Entrance (Normally Front and Centre)
R Rear Entrance
t Toilet
L Wheelchair Lift

This is a short code indicating the configuration of the vehicle, and is this only time where I will use an abbreviation. Where know each vehicle has a steating layout code such as B40F, which would indicate a bus with 40 seats and a front entrance.

For double deckers, the split between the upper deck and lower deck will be given. For example, H45/25F indicates a double decker, with 45 seats on the upper deck, 25 seats on the lower deck, and a front entrance.


The depot is usually given as the name of the town in which the depot is located, but can sometimes be the name of the street the depot is located on.

No distinction is made between a main depot, and a smaller outstation.
