Police are investigating after a stolen vehicle was driven and later abandoned on railway tracks in Cheshunt, Hertfordshire, in an incident an eyewitness described as "like a scene from Grand Theft Auto".
The eyewitness, Ali, said he was left "gobsmacked" by what he saw at Cheshunt station.
Hertfordshire Police said they had been alerted that a stolen vehicle had entered the county from Essex at around 9.30am on Thursday.
The vehicle was located in Cheshunt and officers from Essex Police attempted to speak to the driver, but the vehicle made off from the scene, injuring two officers and damaging several vehicles in the process.
A Hertfordshire Police spokeswoman said the two officers involved suffered minor injuries and did not require hospital treatment, with no other injuries reported.
Footage on social media appears to show the black vehicle driving on railway tracks at Cheshunt station later in the morning, causing major disruption to rail services.
The vehicle was later found abandoned on the tracks near Windmill Lane, Cheshunt, and officers are working alongside British Transport Police (BTP) to search the area for the driver.
The force confirmed the vehicle was not struck by a train at any point.
A spokesperson from BTP said: "Officers received a report of a car on the railway line in Cheshunt at 9.43am today.
"Officers attended the scene alongside colleagues from Hertfordshire Police and Essex Police, and assisted with a search to locate the driver.
"The vehicle has now been removed from the tracks."
A Network Rail spokeswoman confirmed the car had been taken off the line and repair work to the track was due to take place.
Witnesses are asked to contact Hertfordshire police.
National Rail said all lines had reopened but trains may "continue to be cancelled, delayed by up to 60 minutes or revised".
