Hi,
I live beside the recently opened Pelletstown train station. The planning permission (2109/13) effectively no noise increase however we've found there to be a significant increase in noise from intercity diesel trains idling at station and also a service that blows it's horn on approach to the station Monday to Friday at 12:30am (hitting 75db indoors). It doesn't seem particularly obvious how to raise this issue of trains idling and horns with Irish Rail.
Thanks.
