As someone who frequently rides the GL, I've always been curious about some of the seemingly unnecessary slowdowns and speed restrictions. Particularly, I've always wondered why trains slow to a near-stop before they enter a platform, and then proceed into the station at 10 mph. It seems they do this at every station, regardless of whether it is underground or street level. I know GL riders are used to frequent stopping and starting, but to me it seems like some slowdowns are largely unnecessary. I was hoping someone could shed some light on this.
