How fog can cause disruption - and what the industry is doing to minimise any delays

Fog reduces visibility so train drivers have to slow down to make sure they can see track-side signals in time to stop and keep passengers safe. This may cause the train to be delayed.

What the industry is doing to minimise delays caused by fog

  • Investing in the European Rail Traffic Management System which brings signalling inside the train cab, reducing drivers' reliance on track-side signalling and reducing the need to slow down when visibility is poor
  • All trains are fitted with an automatic warning system which rings a bell when the train is approaching a green signal and sounds a horn when the signal is yellow or red
