दौड़ती है हिमालय तट से सागर, हमसफ़र हर राह पर, हवाई जहाज़ों को त्याग कर, करो अक्सर, भारतीय रेल में सफर. - Arpit P

Out of curioisity: Recently I was travelling through Konkan Railway. I found whenever the train reaches / leaves the platform in almost every station, a man notes down something looking at each coach. What he is noting down? Is it the serial number of the coach or something like that?
