    This part imposes minimum maintenance, inspection, and testing 
standards for highway-rail grade crossing warning systems. This part 
also prescribes standards for the reporting of failures of such systems 
and prescribes minimum actions railroads must take when such warning 
systems malfunction. This part does not restrict a railroad from 
adopting and enforcing additional or more stringent requirements not 
inconsistent with this part.
