Old and New Tracks of Tokyo Monorail
This picture shows new and old tracks near the construction site of new international passenger terminal of Haneda airport.
Monorail train receives power from the rail on the side of the track. The powder made by the friction between the rail and the train changes the color of the track.
As I wrote in the description of "Shinkansen 700 Series Train's Roof", the same thing happens on the roof of Shinkansen train.
