On average over 20 million journeys a month are being made on the Elizabeth line, making it the busiest railway in Great Britain according to the latest figures from the transport regulator, the Office of Rail and Road.
For the period Oct to Dec 2022, the report shows that the Elizabeth line recorded 62.2 million passenger journeys. Although that puts it slightly behind Govia Thameslink Railway’s 62.8 million journeys — GTR is made up of four separate railway services (Thameslink, Great Northern, Southern and Gatwick Express).
The figures don’t include Northern Ireland’s NI Railways, but it doesn’t affect the overall findings that London’s newest railway is now the busiest single service in the UK, and a railway that is less than a year old is now carrying one in six of all rail passenger journeys in Great Britain.
This is not unreasonable though as there has been the delay as trains are paused outside Paddington station (to be removed in May), and the service has soaked up a lot of traffic to/from Heathrow Airport, so there’s lot of luggage in the aisles, which can make the trains feel fuller, even if they’re not occupying any more seats.
