Sitting on the doorway of a moving train with 37 tunnels and innumerable bridges (with no edges!!) at 6 am and believe me .... you do get your moments. Train was moving very fast and even though with a shutter speed of 1/500 the time to change it to 1/1000 was not there. Otherwise i could not have got that 2 sec yellow-golden tinge. So it was a moment for me worth the efforts.
