Thanks Ganesh, Jack, Nilanjan, Nevil, Pramod, Shankar, Ashwin, Shiv....for your comments and critiques for motion study images. It has given me one more reason to travel by train. For sake of reference: I used a 80-200mm lense non-is, on Canon 400d.. started off taking shots standing close to the door but sanity prevailed soon after and I sat on my hips about two feet inside of entry door. Locked and crossed my ankles, braced my elbows between knees. 80 mm sometimes brought in door parts ....and settled for 100-150 mm as working range for these shots.
Thanks once again.
P.S. I think I have one more post to go on the subject
Hope it doesn't get monotonous.
