About 40 to 45 passengers were on board the train, which was travelling from Southend, Basildon Council said.
A spokesperson said: “Officers are currently on scene just south of Wickford railway station in Essex following reports that the rear carriages of a train have derailed in an upright position at 2.12pm today.
“We’re responding alongside paramedics and the fire service. There are currently no reported injuries.”
A National Rail spokesperson said all lines were blocked between Southend Victoria and Wickford with disruption expected until at least 4.30pm.
The spokesperson said: “We are dealing with a derailment incident in Anglia, and we are working quickly to understand the situation and to provide assistance where needed.
“We will provide further information in due course.”
It comes after a major incident was declared by British Transport Police (BTP) after three carriages ended up on their side, trapping passengers on board the Southern train near Lewes on Thursday afternoon.
Around 150 people had been on board the service from London Victoria to Eastbourne, which was evacuated.
Two people were taken to major trauma centres with “severe” injuries.
BTP said on Friday the injuries are not deemed to be life-threatening.
