Her system deadened the noise caused by trains running over the tracks by cradling the tracks in a wooden box lined with cotton and filled with sand. The rights to her invention, patented in 1881, were sold to the Metropolitan Railroad for $10,000 and the system was soon adopted by other elevated railway companies.
