If the top speed is 700mph then you'd have 142 seconds of 0.5 g acceleration to get to top speed. How often you'd be accelerating or decelerating would depend on how many intermediate stations there are.

Curves are also specced for 0.5g. That will account for quite a bit more of the total acceleration time than just speeding up and slowing down.
