Massive electric sparks from London underground tube trains, while they battle heavy rain at night. 

The huge sparks that come from the rails are amazing, I love how they create the huge bright arks of electricity.
To really see how amazing London Underground Tube trains are, you have to see them battling and fighting through the heavy rain at night.
The drivers and the trains just keep on going are awesome.
Whatever the weather, they just keep going.
These Metropolitan and Jubilee Line trains are going through Wembley Park station.
