replacement busses

[Chris M]

Is there a standard plan or set of plans for what replacement busses will operate where and at what frequency, etc for any given disruption, or does it need to be arranged separately each time?
e.g. if there was a fault this afternoon that necessitated the shut down for several days of the Central Line between North Acton and West Ruislip, would somebody/somepeople need to sit down and work out what replacement busses were needed and then organise for them? Or would a plan for such occasion already have been drawn up and just implemented?

Chris - I think it is a bit of a mixture of pre-planning (drivers and buses available etc) and some situation-specific planning (estimated passenger numbers needed to be shifted etc). No doubt previous experience of rail replacement services plays a major part in both aspects.

All lines do have specific "plans" for various sections of their line. They give guidelines for such things as likely passenger flows and estimated number of buses, together with the ideal routing of buses.

They are just a guide though and as RussE said, they are subject to alteration dependant on the circumstances at the time.

Of late, engineering work replacement bus services appear to have been arranged to cater for the bare minimum journey. For example, engineering work which closes the Met south of Wembley has seen the bus service run from there to Stonebridge Park. In the past they would have run to cover the entire service (at least as far as Baker Street.)
