TfL website:
The Piccadilly Line has no service between Acton Town Station and Hyde
Park Corner Station in both directions.

Where do trains which terminate at Hyde Park Corner switch from Southbound
to Northbound tracks for their return journey? What is the highest level of
frequency that can be provided north of Hyde Park Corner in circumstances
where all trains are turning back at Hyde Park Corner?
