Abstract

Compound catenary systems on Shinkansen lines will soon enter a period where they will have to be replaced on a large-scale. In order to facilitate replacement and reduce maintenance costs, compound catenary systems can be replaced with simple catenary systems. This study explores new types of simple catenary systems developed for running speeds of about 320 km/h, which is the maximum Shinkansen commercial operating speed. In addition, a simple catenary system for operation up to 360 km/h is also being developed.
