Development of Method for Improving Overhead Line Equipment for Implementation of Stable Current Collection at High Speed

This article addresses concerns with current collection efficiency in Japan’s Shinkansen high speed rail line. The concerns have arisen as a result of the trains’ increasing speeds, since the original infrastructure was designed for trains traveling at 240 kilometers/hour while new high speed trains aim to travel at 360 kilometers/hour. The authors propose a method to modify existing overhead line equipment in order to improve current collection, and supply experimental data accordingly. One strategy for improving collection is to increase the tensile force of the overhead wire, although such measures require a number of other considerations including issues related to expediting the implementation of such an increase. In tests, researchers evaluated efficacy by determining contact loss rate, contact wire uplift, and contact wire deflection. Conclusions support the claims outlined
