Body/Seating Codes

The Local Transport History Society publishes these illustrated PDF booklets to a standard format of 7x5 inches, which makes them easier to read on a PC or tablet screen without annoying scrolling. If you are viewing on a mobile phone we recommend you rotate your phone to the horizontal for best results. The booklets should automatically resize to your device. You will need to have the Adobe Reader installed.

The Adobe DC Reader for Windows, Mac Os, iPhone/iPad, Android phones and tablets can be downloaded HERE.

All our PDF booklets use the standard PSV Circle seating codes when describing the body and seating arrangements for double and single deck buses and coaches as detailed below:

The seating capacity of a double deck vehicle is usually expressed as the number of seats in the upper saloon 'over' the number of seats in the lower saloon - for example 30/26 indicates a vehicle having 30 seats on the upper deck and 26 seats on the lower deck. Highbridge and lowbridge refer to the body layout and not the overall height of the vehicle (i.e. lowbridge has a sunken gangway on the upper deck or part thereof).

Letters placed before the seating capacity:

AB  Articulated Bus
AC  Articulated Coach
B   Single-deck bus
C   Single-deck coach
CH  Double-deck highbridge coach

CO  Convertible open top vehicle

L    Double-deck lowbridge bus
