Fire investigations officers have started searching for evidence pointing to what may have sparked a large blaze at a Nottinghamshire firm.
Around 60 firefighters battled the blaze, which started yesterday afternoon at the Nottingham Sleeper Company.
Group manager Keith Jones, from Nottinghamshire Fire and Rescue Service, told ITV Central that things could have been much worse if the sleepers had been stored differently, as piles of concrete blocks had acted as a fire break.
