The atmospheric railway is one of challenged projects of Isambard Kingdom Brunei who was a British engineer, 1806 to 1859. It was designed and directed by him from the standpoints of environmental benefits, such as no-noise, no-smoke, no-spew, and no-slip on steep gradient. The mechanism to wheel the train was based on the atmospheric force, which was induced by a piston in the pipeline evacuated by steam vacuum pumps. The atmospheric railway was serviced in the line from Exeter to Newton Abbot of the SDR in 1847-48. It is written in references that the trains of atmospheric railway run in VOmph (112km/h) under a weight of 28tones. The railway, however, was abandoned by troubles of air leakage through the slit at the top of the pipeline. In this paper, the mechanism of the system among piston, cylinder, and valve was discussed and the mechanism of impulse in the atmospheric railway was examined by mechanics of movement.
