I've never experienced that, in spite of frequently riding ION.
I'm honestly not sure what it is. You notice it more so if it's moving at a slow speed, on a grade however minor or speeding up/slowing down...but a lot of the times it is entirely random. The train will be going along like normal, then you'll notice a vibration (or something?) and the driver immediately lets off the throttle. You then hear the sand dispensers activate and then it speeds up again...until it does this again. It's definitely unrelated to actual designated points where they must lower the speed or ATC. It's frequently just random. You can be gunning it down the portion between Mill and Block line where it's entirely flat and straight, but once it gets closer to the station or the turn at Hayward, this occurs. But it's not just there, it's anywhere along the system.
