July 1932. 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. However, in December 2013, it was announced that Turnham Green will be made a permanent stop on the Piccadilly line once the line has been upgraded, with work scheduled to commence in 2019 and introduction of the first new train in 2022. A consultation published in January 2014, concluded that the business case would currently have an overall negative impact on business across London from introducing increased stopping at Turnham Green, but did outline the future plans to do so when upgrades had taken place, with passengers benefiting from improvements to the District line and the Night Tube (on Friday and Saturday nights, beginning with the Jubilee, Victoria, Central, Northern and most of the Piccadilly line, then expanding across other lines in subsequent years) from Autumn 2015 in the interim, giving the following conclusion: However, we recognise the continued frustration among those who wish for the Piccadilly line to stop for more of the day at Turnham Green station. The signalling constraints and the size of the train fleet mean that we are unlikely to be able to implement changes in the short term. TfL therefore plans to stop Piccadilly line trains at Turnham Green station all day once the line is modernised and we have a new and larger fleet of trains and a new signalling system. This upgrade is set to commence in 2019 with introduction of the first new train in 2022.In the interim, passengers using Turnham Green station will benefit from the upgrade of the District line. The introduction of a fleet of new larger and walk-through, air-conditioned trains will start this year and be complete by 2016. This will be followed by a new signalling system enabling a faster,
