Concerns have been raised about the noise levels of new London Underground trains, particularly on the Piccadilly line. While some lines like the Central, Jubilee, Victoria, and Northern lines have partially automated trains, the Piccadilly line currently does not. The introduction of automatic train operation on the Piccadilly line was discussed with Sadiq Khan, Chair of Transport for London (TfL).
Labour London Assembly Member Joanne McCartney expressed her concerns to the Mayor regarding the potential increase in Tube noise due to automatic train operation. However, Mr. Khan clarified that automatic train operation is not being introduced on the Piccadilly line at this stage. The new trains will initially work with the existing signalling system, with plans for automatic operation to be considered in the second stage of the upgrade.
Mr. Khan highlighted that noise levels are influenced by various factors, including rail conditions, train design, and track curvature. TfL regularly conducts engineering works and grinding to minimize noise levels across the network. Additionally, efforts are made to address noise and vibration issues by removing insulated rail joints and improving rail conditions.
The first stage of the Piccadilly line upgrade will bring a new fleet of trains by late 2027, increasing service frequency to 27 trains per hour by 2028. The second stage, which includes full signalling upgrades for automatic operation, would further enhance capacity and reduce journey times. However, the progress of Stage 2 depends on the availability of funding, as current estimates for the project are being updated for discussions with the government.
Overall, the upgrades aim to improve the commuting experience, increase capacity, and unlock economic benefits. While Stage 2 of the upgrade was paused due to funding challenges, TfL continues to work towards enhancing the London Underground network for the benefit of passengers and the community.
