Abstract
Based on past research of Material Flow and Stock Analysis (MFSA) focusing on infrastructure, MFSA focused on "railways" has not been performed sufficiently. In this research, focusing on the "Tokaido-Shinkansen" out of "railways", Time-Series Material Flow and Stock Analysis was carried out by dividing it into vehicle section, structure section, train line section and orbit section. We have quantified material flow amount, net accumulation amount, and gross accumulation amount since the launch of the "Tokaido-Shinkansen" to now. As a result, a gross accumulation amount is about 4.13 million tons at the time of 2017, including concrete: about 3.29 million tons, iron: about 760,000 tons, aluminum: about 50,000 tons, copper: about 30,000 tons and stainless steel: about 10,000 t. The material-use efficiency of the "Tokaido-Shinkansen" as of the year 2011 was 11,319 person kilometers / t and it turned out to be ten times more efficient, compared with the national railway average in Japan, 1,059 person kilometers / t.
