A major fire at an Attleborough factory housing gas cylinders and chemicals shut down train services in the area.
The Norfolk Fire and Rescue Service was called to the blaze by Halford Road at around 9am on Saturday.
It sent crews from a number of stations including Attleborough, Hingham, Carrow, Thetford and Dereham.
The experts advised Greater Anglia that it was not safe to run trains through the area, causing the firm to cancel, delay or revise all services until further notice.
By around 11.30am, the fire had been put out and services were allowed to begin running again but Greater Anglia warned disruptions may continue for the rest of the day as a result.
The firefighters stayed on scene battling the flames until they received their stop message just after 1pm.
