Key results

  • For the first time, new data on passenger rolling stock by traction type has been included in the statistics. As of 31 March 2022, 71% of all passenger train operator rolling stock were electric. Diesel vehicles made up 18%, and 11% of the passenger fleet were either bi-mode or locomotive hauled. Seven of the 24 passenger operators had a fully electric fleet.
  • In the latest year (April 2021 to March 2022), 2.2 electrified track km were added to the network. This was due to remodelling at London King’s Cross as part of the East Coast upgrade. The proportion of electrified track was similar to previous years at 38.1%.
  • The average age of rolling stock for all passenger train operators as of 31 March 2022 was 16.9 years. Lumo started operating in October 2021, and has the lowest average age for all operators of 0.8 years.
