SBB turnout points drive mechanisms

RG Teeter
 

I have been watching cab ride videos and noticed that turnouts (crossovers) seem to come with 1, 2, or 3 switch point drive mechanisms (motors). Also have seen 8 and 12 drives. I would like to know what then max or recommended speeds are for these turnouts (switches).

Another question, is the SBB teamwork controlled from one location, or more, and if so what city?

Higher speed turnout means longer moving blades, which requires additional switch motors. I have never seen more than 4 motors though.
