The very dirty Royapuram WAP7 30362 rolls past Sadananda Nagar near Baiyyappanahalli with the 22625 Chennai Central – Bangalore AC Double Decker with all its 12 coaches trailing behind. Check out the patterns someone had drawn on the dirty locomotive! It was about to rain and actually quite dark for that time of the day that I had to crank up the exposure bias. The Double Decker coaches were also all very dirty with fading paint and cracked windows. Anyway, the train belongs to Southern Railway which is not exactly known for its maintenance and cleanliness.
