A part closure will affect Piccadilly line customers from Saturday 10 February until Wednesday 14 February for important engineering work. Vital upgrade works to points at Northfields will be completed during the closure [...] Other important work will also be completed including infrastructure work at Heathrow Airport stations.
[...]
The points at Northfields are on a complicated stretch of track where trains come out of Northfields depot to enter service. The track in this area features some components from the 1930s and must be replaced as the assets are unreliable and maintenance is costly. The closure will take five days because it is not a like-for-like renewal, which means that once the first section is removed, the rest of the track in the area must be removed and replaced.[...]
[...] Customers travelling to Heathrow Airport should use Elizabeth line services. There will be rail replacement buses serving local stations from Acton Town to Heathrow Airport, as well as many local buses.
Richard Jones, Director of Asset Performance Delivery for TfL, said:
[...]
The points are located beneath a bridge, which means they cannot be replaced quickly during engineering hours. This has meant the need for a closure of the line to carry out the work. With the line closed, infrastructure work will also take place around Hounslow and at stations at Heathrow Airport so that TfL can minimise future disruption.
