鉄軌道用分岐器における脱線防止ガード装着手法の基礎検討

抄録

Derailment at a turnout on railway often adversely affects operation. The existing turnout has a guard rail to prevent misguiding, but there is no guard to prevent derailment. In addition, in the large earthquake warning area, derailment guards are installed even in normal sections, but turnout sections are not installed. If it is possible to install a derailment guard in the turnout section, it is effective as an earthquake countermeasure and prevention of derailment during normal times. In this study, the authors investigated the feasibility of derailment guards in the turnout section. As the primary verification, physical verification was performed using a 127 mm gauge turnout.
