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):


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.
