just an update on this.
The light is still broken this morning but just now i received a call from Irish Rail customer services to say that they have chased it with maintenance but essentially its not their fault if they arent around to fix it.
She was wishy washy about whether the station master either knew and did nothing about the problem or whether he didnt even know that there was an issue.
No confirmation as to when it will be fixed.
No response either from the RSC in relation to my email.
