Brighton Main Line railway noise: how it affects nearby properties
The Brighton Main Line links London to the Sussex coast via East Croydon, Gatwick Airport and Haywards Heath, and is one of the most intensively used commuter railways in Britain. The sheer frequency of trains means pass-bys are near-continuous through the peaks, so for homes near the Brighton Main Line the number of events across the day is often the defining factor.
Trains on the Brighton Main Line
Very frequent commuter and airport services between London and the Sussex coast, among the most intensively used routes in the country. Railway noise arrives as distinct pass-bys rather than a steady hum, so both how often trains run and how loud each one is at your property matter — and night-time freight is frequently the key concern.

Dense housing along the route through Croydon, Purley and the mid-Sussex towns sits close to the line, and proximity to Gatwick means some addresses fall within range of both rail and aircraft noise. AcoustaPlot flags aircraft-noise proximity separately, reads any Defra rail contour, and calculates a CRN-based level elsewhere so you see which source, or combination, is likely to affect a specific property.
How AcoustaPLOT assesses Brighton Main Line noise for your property
AcoustaPLOT geocodes your property, identifies the nearest track of the Brighton Main Line, and estimates the daytime (Lden) and night-time (Lnight) levels at your facade — reading Defra's mapped railway-noise value where available, or calculating it with the Calculation of Railway Noise (CRN) method and terrain data elsewhere.
