Wikipedia:Featured picture candidates/Arcing pickup shoe

 
Electricity arcs between the power rail and pickup shoe of a London Underground train. Sparks like this are quite normal and occurs when the electric power collection "shoes" of a train that is motoring (ie: drawing power) reach the end of a section of electric power rail.

This photograph by SPSmiler is a striking image of the power of electricity, and of the dangers of third rail electrification. It is used to illustrate the Third Rail and Electrical arc articles.
