Brightline has never nor will ever use those platforms, TriRail will. TriRail should have paid far more attention to their quality than Brightline.
From what I've read so far from the pdf linked earlier, it is the Bombardier door jams vertical clearances causing the problem with an 0.8 of an inch clearance. and the Rotem BiLevels causing the problems with the weight. At least the most limiting problems with both issues. The weight problem is more associated with the fixed direct concrete slabs vs using regular ballast, and higher wheel vibration forces with the fixed direct concrete.
I suppose there are many engineering options available to fix the issues. TriRail will probably ask for the most expensive solution, Brightline the least expensive solution. Time will tell. Of course, TriRail will want to fix all the blame in Brightline, but they have dropped the ball with active quality assurance with work on their platforms. The time to identify the problem was during construction, not during the testing phase.
