Is there a logic to the numbering of bus routes in the London area,

disuse?

I defer to those who know what they are talking about but I think there
were
at least some basic rules. For example 1-99 were routes that orginated
in
central London, 2xx were once single deckers, 3xx were London Country
routes
north of the river, 4xx London Country south of the river and so on.

Which was broadly true when London Country was part of the LT Network
prior to 1970. Route development since that time plus the introduction
of many lettered routes means the logic no longer applies in a coherent
manner. Deregulation of services in surrounding counties has also had
some effect on numbering convention on cross boundary services.

Thanks Paul,

Any idea about 1xx?
