Sir, - Wouldn't it be an idea if there were notices at all railway crossings (DART and Iarnrod Eireann) asking drivers to turn off their engines while waiting for the train to pass and the barriers to rise?
This simple measure, which is standard at all such junctions in Germany, would be a small contribution towards reducing both the air and noise pollution. It might even be a saving in the motorist's pocket. - Yours, etc.,
Thornhill Road,
Mount Merrion, Co Dublin.
