I'd assume it would be similar to SheiKra's brake run that uses LIMs to slow the train down quickly and smoothly, and then friction brakes after that. Otherwise that's going to be a really long 1 block brake run.
And for anyone who is curious, this is the new track piece in the preview center. . . Also, it's interesting to me that they have barriers around this piece when they didn't have them around the last piece.
