The British innovative engineer, Isambard Kingdom Brunel (1806-1859) had developed the atmospheric railway system and serviced commercially in South West in England during the half a year in 1847 to 1848. The driving force of the railway system was based on a vacuum force produced by pressure difference between vacuum and atmospheric pressures. The system was environmental friendly because of no-smoke, no-noise, and no-spew. In the present paper, the authors introduce a similar but different railway system which runs by compressed air pressure. This project has been conducted as monodzukuri education for students of Soma High School, Fukushima. The small scale model of the compressed air railway system has produced and tested. The driving force of the system is generated by expansion force of and at a flat tube constrained tightly by two rollers. The students were devoted to study the mechanism and performance of the system. The railway system has a potential to be used in public transportation under horizontal and inclined surface and subsurface ways in future.
