Engineering work 25-26 November 2023 (Heathrow T5)

[Dstock7080]

Due to planned Heathrow engineering works on Saturday 25 and Sunday 26 November, the Elizabeth Line and Heathrow Express will not be running to Heathrow Airport all weekend. Piccadilly Line trains will be operating between central London and Heathrow as normal, serving Heathrow Terminals 2 & 3 and Terminal 4, but they are likely to be busier than usual and no trains will run to or from Heathrow Terminal 5.

An inter-terminal transfer bus service will be running between Terminals 2&3 and Terminal 5, starting from Heathrow Central Bus station. Passengers wishing to travel between Terminal 4 and Terminal 5 can use the free H30 bus or TfL buses 482 and 490 between Hatton Cross, Terminal 4 and Terminal 5.

In connection with track renewal work between Sudbury Town and Alperton and power supply work at Heathrow Terminal 5, the Piccadilly Line train service will be suspended Acton Town-Uxbridge and Heathrow Terminals 2&3 and Heathrow Terminal 5 from approximately 01.20 on Friday night 24 November until close of traffic on Sunday 26 November.

Revised train service, Saturday 25-Sunday 26 November:-
Cockfosters-Heathrow T2&3 (via T4 loop), every 5min
Arnos Grove-Northfields (reversing via Northfields depot) every 10min
These services combine to provide a 3½-3½ minute service between Arnos Grove and Northfields
At Heathrow T4, trains will generally stand for 1-2 minutes before continuing to Heathrow T2&3
At Heathrow T2&3, both platforms will be served by eastbound trains. Most trains will stand for 7-8 minutes, before continuing eastbound to Hatton Cross.

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 )

Is this what happened before the T5 extension?

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.

Between 1986 and the closure of the T4 loop in 2005 (for construction of the extension) eastbound trains used both platforms at Terminals 1, 2 & 3, alternating between platforms. Trains had several minutes booked to stand there.

This stand time for loop trains is now taken at Terminal 4.
