It's interesting... I wonder if extending the step while the train is in motion has the potential to knock people down who's currently on the platform and standing too close to the train.
> since the step itself does not extend over the platform (it reaches only 63.5 inches from vehicle center line when fully extended) there can be no hazard to passengers
I dunno about that. What if they had an umbrella or grocery bag or such dangling over the platform edge?

Maybe the more relevant question is how was it done before? Did the old train also have slowly-extending steps? How is it handled in other countries with functional train networks?
