Through most of the early and the middle 19th century, Horsham's population grew slowly. Its character was not altered in any significant way until about 1872, when the North Pennsylvania Railroad extended a rail line from Glenside to New Hope and established a station in the nearby community of Hatboro, 2.75 miles (4.4 km) east of the nucleus of Horshamville. Horsham-Hatboro-Byberry Road provided easy access to Hatboro's station and, as a result, residential development began along the road, virtually linking the two communities together. By 1890, the township's population had reached 1,300.
