Numbering of bus routes change
Historic numbering change
Historically, bus routes were grouped by the type of service that they provided.
The 1924 London Traffic Act used the Bassom Scheme. It was named after A.E. Bassom of the Metropolitan Police who made it. Changing and short lines used letter suffixes. Also, the numbers were grouped by the company that operated the route.
|Route Number||Former type of Service|
|1–199||"Central Area" red double-decker services|
|200–289||"Central Area" red single-decker services|
|290–299||"Central Area" night routes|
|300–399||"Country Area" north of the River Thames (rural services were operated by London Country Bus Services after 1970)|
|400–499||"Country Area" south of the River Thames|
|701–799||Green Line Coaches|
|800–899||"Country Area New Towns" routes|
