A woman has been hit by a train between Staines and Feltham station.
Officers from British Transport Police (BTP) and paramedics from the South East Coast Ambulance Service were called to reports of a person struck by a train at Ashford station.
The incident happened at around 10.15am on Tuesday (March 28).
A spokesman for BTP said: "BTP are currently at Ashford (Middlesex) station following reports that a person was struck by a train.
"Police were alerted shortly after 10.15am.
"Officers are on scene alongside paramedics from the South East Coast Ambulance Service who are treating a woman for injuries.
"At this stage the severity of her injuries are unknown and paramedics are being supported by the Fire and Rescue Service.
"This incident is not being treated as suspicious.”
South West Trains (SWT) reported disruptions including cancellations and delays will continue until at least 1pm.
For around one hour power supply to the trains had to be turned off to allow emergency services to work safely in the area, SWT reported earlier.
As a result no trains were able to operate on the lines running between the stations.
SWT said in a statement: "A person has been hit by a train between Staines & Feltham earlier today.
"All lines were blocked whilst emergency response teams attended to deal with the incident.
"The location of the incident caused a knock on effect as there are only two lines available through this area.
"The lines have now re-opened and trains are on the move but trains may have to be cancelled, altered or revised at short notice.
"Some services may also be diverted via an alternative route or terminated and started back from different locations."
South West Trains arranged for replacement buses between Windsor to Hounslow and Weybridge to Staines.
