City Thameslink, Blackfriars and St Pancras International are the three major London train stations with the highest percentage of cancellations, according to an analysis of data by The Standard.
City Thameslink had the highest rate of cancellations, at 10.4 per cent of trains, between July 25 and August 16 2025, according to the Office of Rail and Road (ORR).
Some 1,259 of 12,033 scheduled stops were cancelled over that period.
This was followed closely by London Blackfriars, where 10 per cent of scheduled trains were cancelled, meaning 1,636 of 16,295 trains did not arrive at the station.
At London St Pancras International, a total of 1,856, equating to eight per cent of trains, were cancelled.
The table below reveals train cancellation data at London’s 50 busiest stations.
Of London’s busiest stations with the most cancellations, 15 were on the Elizabeth line, including busy commuter stations Liverpool Street, Paddington and Tottenham Court Road.
At Farringdon, 5.8 per cent of journeys were cancelled, followed by Heathrow Terminal 4 where 4.5 per cent of trains were cancelled.
Among the top 50, 12 London Overground stations were listed as having among the highest cancellation rates.
Highbury and Islington was the Overground station with the highest percentage of cancellations at 5.5 per cent, followed by Richmond at 5.4 per cent and Shepherd’s Bush at 4.9 per cent.
Other Overground stations with high a high percentage of train cancellations include Clapham Junction, Euston and Willesden Junction.
The most common reasons for rail delays and disruptions include extreme weather, such as flooding, high wind, fog and extreme heat, according to National Rail.
Infrastructure issues can also cause delays, including points failures, signal failures and broken rails, as well as other external factors including animals on the line, trespassing and lineside fires.
The recent publication of rail cancellation data comes after the Department for Transport launched an initiative across England in March to display data showing the punctuality of trains at stations.
Performance data went live across 1,700 stations in Mach, showing the percentage of train cancellations, as well as the punctuality of trains at stations, which the government deemed a “new era of rail accountability for passengers”.
The Department for Transport said the purpose of publicly displaying such data was to “hold operators to account” and encourage them to drive up “efficiency and productivity”.
Data displayed at stations can also be found on the ORR’s data portal.
Emma Pickard, network operations and performance director for Thameslink and Network Rail said: “We understand our service hasn’t always been good enough, and we’re deeply sorry for the disruption this has caused to passengers. People rightly expect trains to run reliably and we understand how frustrating it is when trains are cancelled. We take full responsibility for the impact this has on our passengers.
“Across the industry we are working hard to do everything we can to prevent cancellations and make services more reliable. This includes tackling issues such as signaling and power supply faults, improving train crew availability, and investing to make the network more resilient to severe weather and other unexpected events.
“When incidents outside our control do occur, such as poor weather or trespass we aim to restore the service as quickly as possible, however on a network as busy and complex as Thameslink’s the disruption can be felt widely.
“At times we have to make the very difficult decision to cancel some trains to get the timetable back on track, and prevent further disruption spreading across the network. We know this adds to the frustration, but it is sometimes the best way to keep the majority of services running reliably.”
A spokesperson for Great Western Rail said: "We recognise how important it is that our trains are consistent and reliable, and work hard to ensure that they are. We are pleased to see that almost 98 per cent of our planned services from London Paddington operated during this period.
"We're committed to working with our industry partners Network Rail as we seek to continue to improve the reliability of our services and the infrastructure on which they depend.
“We understand how frustrating delays can be and are sorry when they do occur.”
A TfL spokesperson said: “We are committed to offering our customers the most reliable service possible and we are proud that the Elizabeth line and London Overground continue to be among the UK’s highest performing train operators, offering frequent and high-capacity services with very high levels of customer satisfaction.
“These cancellation statistics take into consideration all operators so can't be fully attributed to our services.
“On the Elizabeth line and on London Overground lines, train cancellations occur for a number of reasons, many of which are out of our control.
“We work closely with Network Rail, which is responsible for the maintenance of the track, signals and other infrastructure, and GTS and Arriva Rail London which operate services on our behalf, as well as the freight industry, to ensure any delays and cancellations are kept to a minimum wherever possible.”
