In winter almost every morning you can attend a show in the stations: the train lights up, on the roof, at the pantograph.
So where do these flashes come from? It's dangerous ? And what is this pantograph?

Ah yes, this thread in the air, why is it there? What is the catenary?
25000v catenary and 1500v catenary ... yes but more?
And what happens when it breaks?
The frost is beautiful in the morning but on the catenary what does it do?
And what are they doing at the SNCF to fight against that?
Scraper train ... what is this thing?
A series of questions and answers that make up the story of the catenary pantograph couple.
