To provide a better interchange with the Richmond branch of the District line, Piccadilly line trains began stopping at Turnham Green station in the early mornings (from the first train until 06:50 Monday to Saturday, 07:45 on Sunday) and late evenings (from 22:30 until the last train) only from 23 June 1963. During the rest of the day they run non-stop through the station as before. Local residents have been campaigning for more Piccadilly line trains to stop at Turnham Green with trains only stopping in the event of delays to the District line whereby large numbers of passengers are left waiting on the platform or occasionally while scheduled maintenance work is carried out.

Is it true that does the piccadilly line stop at turnham green on sundays?
yes
