Ref # 202107-01
Status Open / In progress
Occurrence Luas isolation irregularity, Kylemore to Suir Road, 5th January 2021
Occurrence Date 05 January 2021

Basis for Recommendation

The pantograph of Tram 4010 bridged the energised section at Heuston to the de-energised section at Suir Road and resulted in the short circuit. The Section Insulators allow a pantograph to bridge both sections of the Overhead Contact System. As a result, the RAIU make the following safety recommendation (CaF-01):

Recommendation

Transport Infrastructure Ireland (TII), in conjunction with Transdev, should consider fitting Section Insulators with diodes to prevent the passage of current from an energised section into a de-energised section when bridged by a pantograph.
