Answer (1 of 4): It depends on the load on the axles that can accelerate/brake and the force they can use, compared to the weight of the train (the force required). Using check valves withinthe ACH, the compressed air is trapped, and the kinetic energy required to bring the train to astop is converted to potential energy as the compressed air. It rises an average of 4.7 feet for every 100 feet in length. Among the politicians and other dignitaries speaking that day was a large banner showing two large hands reaching across North America with the phrase May the Bond be Eternal.According to a period newspaper account, US Senator Newton Booth remarked: what does the symbol upon that banner mean?
