In 1879, early in the construction of the tunnel, workers came upon a large freshwater spring which could not be plugged. Consequently, the spring water must be continually pumped out of the tunnel and into the river from a pipe located about sixty metres northeast of the station. The pumping station is directly over the deepest part of the tunnel. Besides pumping water out of the tunnel, the station also pumps fresh air in so that it can exhaust out of both tunnel mouths.
