Recommendation: 2014-010

Basis for Recommendation

In relation to the design weakness of the autocouplers, where the autocoupler do not fail safe (CF-02), the RAIU make the following safety recommendation for autocouplers the entire EMU fleet:

Recommendation

The CME (IÉ RU) should review and modify their design for the EMU autocouplers to ensure a more robust coupler circuit that will provide assurance that both coupler electrical heads have connected correctly and that coupler circuits are continuous throughout the train consist. Any modification made should be documented in Rolling Stock Design Standards.
