Pump Governor - Westinghouse Air Brake
Today, the air brake is the standard, fail-safe train brake used by railways worldwide. Early train brakes were hand operated and largely ineffective. To get higher and safe speeds, American inventor George Westinghouse brought out an air brake in 1869. Unfortunately, if a hose burst or the train broke in two the brakes on the entire train became useless. Also the brakes worked unevenly throughout the train and could cause the carriages to collide. Westinghouse introduced the automatic air brake for steam trains in 1873. Putting a quick-action triple valve and an auxiliary reservoir under each vehicle ensured independent braking power and the automatic application of the brakes on the whole train. The pump governor shown in this late 19th c illustration acts as an automatic throttle valve to maintain the desired system air pressure

Waimea Canyon, Kauai, Hawaii, USA
Waimea Canyon, also known as the Grand Canyon of the Pacific, is a large canyon, approximately ten miles (16 km) long and up to 3, 000 feet (900 m) deep, located on the western side of Kauai in the Hawaiian Islands of the United States. Waimea is Hawaiian for reddish water, a reference to the erosion of the canyons red soil. The canyon was formed by a deep incision of the Waimea River arising from the extreme rainfall on the islands central peak, Mount Waialeale, among the wettest places on earth

MFB North Kensington fire station, West London
North Kensington was one of the latter fire stations to be built by the MFB in 1882 prior to the creation of the London County Council in 1889 and the changing of the name of the MFB to the London Fire Brigade. Located at 58 Faraday Road, the station remained operational until 1986 when the new North Kensington fire station was opened in Ladbroke Grove
