The Brunei's atmospheric railway (BAR) directed by the great engineer, Isambard Kingdom Brunei (1806-1859) was the longest distance commercial application in England. The traction force of the BAR was the pressure difference between front and rear faces of the piston in a pipeline laid between the rails. The BAR was an environment-friendly railway which could run under no-noise, no smoke, and no soot, because it was powered by stational steam engines. The atmospheric system has also an advantage in running on steeper gradient railways. The present paper has introduced the early applications of the atmospheric and pneumatic systems in Ireland, England, France, etc.
