LU Possessions Strategy

Tubelines were responsible for the upgrade of London Underground's Jubilee, Piccadilly and Northern Lines. A major problem for implementation was the short possession times available to contractors, mainly during overnight engineering hours. We were appointed to investigate the wider impact of longer closures on the Northern Line and to identify alternative public transport provisions.

Northern Line Closures

We undertook a study investigating the effects of partial line closures of the Northern Line. Each branch consists of 5 to 9 stations, which were analysed in detail. Alternative bus and pedestrian routes were chosen for their practicality and convenience for passengers.

Bus Routes to Alternative Stations

The study shows the most convenient bus and pedestrian routes from each station on the Northern Line to neighbouring stations during closures. Special consideration was given to disabled passengers, possible road closures and planned engineering works on other underground lines.

Line Closure Bus Provision

On branch on the Northern Line, proposals were developed for where provisional bus routes could be provided in parallel with the underground. For the duration of the closure, this additional service would take the pressure of surrounding stations and help to minimize additional travel time for passengers.
