I still wonder what would happen if a child, animal or object was on the tracks - you wouldn't have time to react and even at that speed could still do significant damage. Sorry to be a H+S bore...
At the end of the day trains aren't driven on sight, this is why signalling is provided.
As far as the original question goes, the answer is it depends on whether that procedure is allowed by the railway's rule book. Doing token changes on the move is no longer allowed on the mainline (although that's not to say it doesn't occasionally happen - I was surprised to see it happen somewhere recently at a location I'm not going to write). However doing token changes on the move it part of the heritage railway experience, so personally I don't have a problem with it.
