Engineering work 25-26 November 2023 (Heathrow T5)

The Piccadilly Line is also closed between Acton Town and Uxbridge on the weekend of 25/26 November 2023 (Met line to Uxbridge will still operate )

When Heathrow Terminals 2&3 opened both platforms were used as terminating platforms like at most terminating stations.


Then in 1986 T4 loop opened so all trains operated via T4 and only via the eastbound platform 2 at T2&3.

Then in 2008 when T5 opened the platforms at T2&3 became used for T5 services with T4 services only using the eastbound platform. 

From the T4 loop trains can access both the westbound and eastbound platforms at T2&3 before using a crossover east of the station to get onto the eastbound line. I imagine this arrangement this weekend allows the usual 8-10 minute crew break at T4 to move to T2&3 to keep the service moving.
