Actually when I was small 9-10 years old, we use to play "Kit-Kit" regularly, I don't what it would be called in proper english but it involves a player hopping 8 squared boxes with one leg in the air, while kicking a small stone across the boxes simultaneously.......
Nevertheless we used to be playing regularly in 'make-shift playing area'.......which happened to be just by Dhanbad station... We use to play till 7PM . At around Shaktipunj would arrive from Howrah and get it's loco changed to Diesel at Dhanbad....Back then the DHN-RNC....CIC section all were non-electrified.....When the ALCO used to pass us by,chugging as usual.....we found a reasonable similarity between the chugging "KHIT-KHIT' sound and our game "KIT-KIT".....hence we named it as...
more... "KHIT-KHIT" Engine.............
What I commented then was just nostalgia returning back...........................................................
