Rail noise monitored
Rail Services Australia has installed equipment between Woy Woy and Tascott in attempt to reduce wheel noise from trains.
Meanwhile, the Rail Access Corporation's "Greenline" has installed devices on two Koolewong homes to monitor the noise.
Residents had complained that the noise coming from freight trains was both louder and more frequent than previously.
Presented with a log of times that the noise occurred, "Greenline" decided to measure the noise itself.
The measurements revealed the road traffic noise was present but that "the trains are much louder".
Between Woy Woy and Tascott stations, Rail Services Australia has installed "wheel flange applicators", which lubricate the wheel flanges of a train as it passes, to reduce the level of "wheel squeal".
