In common with all London transport authorities from 1933 to 2000, the public name and operational brand of the organisation was '''[[London Transport]]'''. ==London bus route historic numbering== Historically, bus routes run by London Transport were grouped by the type of service that they provided. The 1924 London Traffic Act imposed a numbering scheme known as the Bassom Scheme, named after [[Chief Constable#Metropolitan Police|Chief Constable]] [[A.E. Bassom]] of the [[Metropolitan Police]] who made it. Changing and short lines used letter suffixes. The numbers were grouped also by the company that operated the route. The numbering was revised in 1934 after London Passenger Transport Board was formed:<ref>{{cite news|title=How are bus routes (especially London bus routes) numbered?|work=The Guardian|location=London|url=http://www.guardian.co.uk/notesandqueries/query/0,,-197292,00.html}}</ref> ==References== {{reflist}} ==Other websites== * [http://www.railwaysarchive.co
