The language that instructions the DOT to create the standards and on what basis those would be created was not modified from before. What was modified what systems would be in scope and added language about explictly including structural inspections for raised elements and shutdowns for inspector safety. The DOT is going to have to create standards for these new systems, and be site specific... and written considering:
"Standards must be site-specific for fixed-guideway transportation systems and shall be developed jointly by the department and representatives of the affected systems, giving full consideration to nationwide industry safety norms relating to the development and operation of fixed guideway transportation systems."
Yes, the points about the potential for government abuse are there (and always have been) -- but gripes about 'vague' laws or non-existent standards are hand waving and not really valid arguments.
