Four fire engines and around 25 firefighters were called to a grass fire on Norton Road in Wembley.
Around 50 metres of grass and bushes on the hillside of a railway were damaged by fire. The power was isolated and there was some disruption to London Underground services as crews worked to make the scene safe. There were no reports of any injuries.
If you see a grass fire, don't attempt to put it out yourself as grass fires can travel very quickly and change direction without warning. Call the fire Brigade and let us know where the fire is.
The Brigade was called at 1448 and the fire was under control by 1650. Fire crews from Wembley, Park Royal and Northolt fire stations attended the scene.
The cause of the fire is under investigation.
