On October 9, 1834, the Dublin and Kingstown Railway commenced operations, linking Dublin with Kingstown (now Dún Laoghaire). Spanning over 12 kilometers and engineered by Robert Stephenson, it was the first railway in Ireland to offer scheduled steam locomotive services. The new line drastically reduced travel time compared to coastal coach services and quickly gained popularity among commuters and leisure travellers. Its success spurred further railway development across Ireland and influenced engineering standards throughout the British Isles. This milestone marked the beginning of a transformative era in Irish transportation.

On October 9, 1936, the monumental Boulder Dam on the Colorado River produced its inaugural hydroelectric power. The new facility delivered 30 megawatts of electricity to Los Angeles, illuminating the city and fueling local industries. Constructed during the Great Depression, the dam employed thousands and stood as an engineering marvel of its era. It provided flood control, irrigation water, and a renewable energy source for the growing American Southwest. Renamed Hoover Dam in 1947, it remains a symbol of Depression-era ingenuity and public works achievement. The project transformed regional development and set new standards for large-scale infrastructure.
