13/09/2017 Derailment Dun Laoghaire

Dublin13 · 15-09-2017, 13:46

What is normal procedure when points fail?

How are they fixed, does someone have to be sent from engineering to fix them or is there something else that can be done?

Procedure is normally to run the points back and forward a few times to clear the issue, then get a member of station staff to go trackside and ensure there isn't anything obstructing the points and follow the proceedure

The exact procedure for the exact points in Dun Laoghaire

If I was a betting man, one of two things happened next

1. A stretcher bar fails and the gauge wideness just enough for the train derail, there was a new stretcher bar installed post incident
2. The lead axle wheel strikes the wooden scotch and lifts it such that the second axle climbs over it

Neither of those things happened - there was some damage done in the course of the derailment, hence the new stretcher bar.

So what do you think did happen then seeing as you know that two things didn't?

Something went wrong

The RAIU will find it out, somewhere, someone in Irish Rail messed up, thats the only certainty in all this. No third parties involved thats a certainty the derailment happened under degraded operating conditions.

Once that is done the CRR will circle around and decide if legal action or other enforcement measures are to be taken against Irish Rail.

I hope that the investigation really exposes the failings of Irish Rail in this, honestly I just had a look over at Boards and some of the things which I have seen there make me despair, you would think that customers self detraining is seen as the biggest problem in the whole incident rather than the poor comms and also how this incident was to happen in the first place.

I despair about IR really they're just not a customer focused operation in any shape or form when disruption happens and the worst thing is that they don't even want to recognise and address their own failings, no surprise that there are questions about the culture in that company.
