Inclusion of Elizabeth Line data
Since services in the central section of Crossrail started running in May 2022, there has been a significant uplift in National Rail journeys counted in the LENNON database. Before May 2022, Crossrail services were operated under ‘TfL Rail’ branding, which ran between Paddington and Reading or Heathrow Airport, and between Liverpool Street and Shenfield. These journeys were direct replacements for previous National Rail services and were counted in LENNON. Following the opening of the central section, when Crossrail services began operating under ‘Elizabeth line’ branding, these journeys started being recorded in LENNON, replacing some journeys that would have been taken on other modes such as London Underground and DLR.
From September 2023 onwards, the ‘Daily domestic transport use by mode’ statistics include a second rail usage timeseries which excludes Elizabeth Line services (and other relevant services that have been replaced by the Elizabeth Line) from both the travel week and its equivalent baseline week in 2019, where appropriate.
Before May 2022, services which would correspond to the current western Elizabeth Line services were operated by TfL Rail and Great Western Railway (GWR). Therefore, journeys allocated to the Elizabeth line in the current travel week, and journeys allocated to the relevant TfL Rail/GWR services in the equivalent baseline week are removed. This allows for a more meaningful like-for-like comparison of rail demand across the period because the effects of the Elizabeth line on rail demand are removed .
This time series excluding Elizabeth line services presents a lower recovery than the time series which includes the effect of Elizabeth line services.
From September 2023, the ‘Daily domestic transport use by mode’ statistics bulletin exclusively refers to the time series excluding Elizabeth Line services, however, the time series including Elizabeth Line services is still available in the accompanying data tables.
