Why does the ground shake when a train goes by?
Why does the ground shake when a train goes by? The main sources of ground vibrations generated by railway trains are dynamic forces transmitted from tracks to the ground. These forces are associated with complex processes of interaction of moving train axles with railway tracks supported by the elastic ground.
How do you sleep when you live near a train?
- Earplugs: Wearing earplugs can combat the train noise and help you sleep through the night.
- White noise: A white noise machine or app will provide a constant low-level background noise that can help you sleep through occasional train whistles.
