AN EMERGENCY operation was launched after a tanker containing 94,000 litres of chemicals derailed near Harwich International Port.

The incident happened in a yard at Parkeston Quay shortly after 8pm yesterday, but the tanker remained upright.

Essex County Fire and Rescue Service said there had not been a leak.

Six fire engines from Dovercourt, Manningtree, Colchester and Maldon were sent to the scene due to the risk of fire or explosion.

The tanker was being carried by a freight train and contained 94,000 litres of chemicals, believed to be petroleum distillate. It is thought the train may have been heading to the Carless Refinery next to the port.

Rail operator One said it had been forced to suspend all passenger services between Manningtree and Harwich last night as a safety precaution. A replacement bus service was instated.
