Roy's is an interesting example though - trains do move very quickly, but unlike, say, a footballer running towards you, a train's path should be very predictable along its tracks. Roy, do you find your AF system successfully tracks the train coming towards you and keeps it in focus at all times? It's a good test...
Yes, I find that the AF system keeps the train in focus I usually set the camera on Sports Mode with continuous shooting and do a 20 - 25 frame burst and they are all in focus, have only had a couple that have not been in focus, but put that down to me moving right at the end to see if I could catch the number of the train before it disappeared in the distance.
