Fire crews are tackling a large fire at an industrial site in Wembley.
London Fire Brigade (LFB) were called to Wembley Commercial Centre, on East Lane, at 6.50pm on Friday (April 6).
A LFB spokeswoman described the building as an "industrial site" and added the "ongoing fire involves cylinders" which pose a risk.
Firefighters in six appliances were still in attendance at 8pm.
Images on social media show large visible flames coming from the building and a lot of thick black smoke filling the air.
A photo taken on a passing train some distance away shows how much smoke there is.
The Bakerloo Line has suspended services between Stonebridge Park - Harrow & Wealdstone due to the incident, but good services continue on the rest of the line.
London Overground routes are also affected. There is no services between Willesden Junction - Harrow and Wealdstone.
The Transport for London (TfL) Travel Alerts Twitter account tweeted: "Tube and rail services in Wembley are affected. We will resume service once the fire brigade have done all their checks and deem it safe to do so."
