They call this ratio the grade of the roadbed, usually written as a percentage. Along the coast, commercial railroad grades are usually less than 2%. In the moun-tains, they may go as high as 4%. Highway grades are usually less than 5%. The steepest part of the Mt. Washington Cog Railway in New Hampshire has an exceptional 3 7.1% grade.
