Basis for Recommendation

It can be hard to defend against the sudden onset of Low Rail Adhesion conditions caused by changing weather conditions. Therefore it is important that the train has an ability to counteract this. Sanding systems are shown to improve stopping distances by conditioning the wheel/rail interface and improving the co-efficient of friction available. As a result the RAIU make the following safety recommendation:

Recommendation

Iarnród Éireann (Railway Undertaking) should review all traction fleets that do not have sanding capabilities, and fit suitable systems to minimise the risk of low adhesion incidents.
