All trains have been cancelled between Reading and London Paddington after a person was struck by a train.
Great Western Railway (GWR) said that all lines in the area have been blocked and passengers should expect delays of up to 90 minutes or cancellations as emergency services deal with the incident.
The rail operator also confirmed that the Elizabeth Line, which runs on the same line, is also affected.
GWR tweeted: ‘Due to emergency services dealing with an incident between Reading and London Paddington, all lines are blocked.
‘Train services running to and from these stations will be cancelled, delayed by up to 90 minutes or terminated at and started back from Reading.
‘Disruption is expected until 21:00.’
TfL confirmed there was a ‘casualty’ on the track. In an update, they said: ‘No service between Reading and Maidenhead while emergency services deal with a casualty on the track.’
Passengers have been informed that tickets will be accepted on South Western Railway between Reading and London Waterloo, Chiltern Railways between Oxford and London Marylebone and London Underground services.
National Rail said: ‘Emergency services dealing with an incident between London Paddington and Reading means trains running between these stations may be delayed by up to 90 minutes or cancelled. Disruption is expected until 9pm.’
The Elizabeth Line is already closed today and tomorrow between Paddington and Abbey Wood, sparking further disruption.
Earlier today, passengers also faced delays on the Hammersmith and City, Circle, Central, Metropolitan and Piccadilly lines.
It comes just weeks after many GWR and Elizabeth line services to and from Paddington were cancelled or delayed for several days because of a broken rail between the west London station and Reading.
Meanwhile, last month thousands of passengers were stranded on trains for several hours because of a problem with overhead wires.
Seven trains carrying thousands of passengers including Rachel Riley and James Blunt were trapped for four hours in London in the evening rush hour without power, with groups eventually forced to walk down freezing tracks in the dark a part of an exit strategy.
A day later, speed restrictions were imposed due to a broken rail crossing, which is used to transfer trains from one line to another.
Passengers have regularly been left frustrated by the £19billion Elizabeth Line which has been plagued by delays.
MailOnline revealed last month that the line has suffered the biggest drop in reliability of all UK rail operators – cementing its place as one of Britain’s worst train services.
British Transport Police have been contacted for comment.
