Copenhagen S-train traffic on the Web: Byens Puls

Byens Puls is a Java applet downloaded to the user's PC, running in the browser, and requires a Java virtual machine installed on the user's PC. It updates every 3 seconds. The map of the S-train lines is a fixed background. Train symbols are drawn on top of the background drawing. Each line block is mapped to a fixed point on the background drawing on each S-train line.
