We can protest all day and night about rail noise, but if it can't be fixed we would be wasting our time. Fortunately there are many possible solutions to the rail noise.  We have been working with Sydney Trains on some and gently suggesting others to Sydney Trains with no response.  I will set out on this page any technologies which we come across which may be helpful.  Rail noise is a big issue in Europe for two reasons - they have a lot of trains and the environmental regulations have put strict limits on the noise that can be produced. As a result, there are many innovative solutions coming to light.
