The drivers of the ION system have being doing this from day one on all the cars I been on. It was weir and had to asked why and was told why to keep them from being bore and on their toes.I saw that on an episode of Mighty Trains covering one of Japanese lines. It looked a little weird when the engineer/driver did it alone in the cab, but if it works . . .
it's kinda-sorta like a cop directing traffic (well, the remaining few that are actually good at it).
