This has pretty much already been confirmed by those in-the-know to be incorrect. They're 100% LSM stators, and at no point have we seen the 'anticipation stall' effect from them in testing. They almost certainly can be used as a trim, but they have a dual purpose of being able to give the train a little boost over the crest if it doesn't make it. Also, the power cables run down the track on the JP side.
Someone can correct me if I'm wrong- but if I've been keeping up with it, there's three separate power hubs(not sure what to call them) for LSMs on site. Two are on the roof of the station, and one is housed in the first show building.
