Brunel in England, to start the subaqueous tunnel on its 1,350 feet long, first used for cable cars, later pedestrians, and eventually for the first time a shield combined with air pressure, and in the same year this Brunel's original tunnel shield design was significantly improved the work of Many years passed before the first tunneling use of compressed air occurred in but, owing to the inrush of the river into the works on two occasions through breaks in the stratum of clay, and financial difficulties, only completed in 1843.
