The filament lamps in signal PL278 were difficult to read in sunlight. A Signal Sighting Committee was not convened to consider the problem and the measures taken by the SET Department to resolve this issue were found to be ineffective. The change was not verified for effectiveness, allowing the problem to remain. Therefore the RAIU make the following safety recommendation:
Recommendation
Iarnród Éireann should ensure that the Signal Sighting Committee is informed when train drivers report difficulties viewing a signal and the Signal Sighting Committee should verify that the reported difficulties are addressed effectively.
