There are no legal limits to noise from existing railways.
If you think that noise levels are affecting your health contact your local council who will investigate on your behalf.
If noise from a new railway affects your property you might be able to get sound insulation for your home. Contact the relevant rail authority - ask your local council for their details.
If particular trains are causing you a problem, speak to the company running those trains.
Find information on train operators on the National Rail website or call Network Rail.
