Why do trains shake so much?
Why do trains shake so much? Summarising from the article: the vibration arises because the track is not completely smooth and the train wheels are not perfectly circular. As the train moves along thetrack, the result is an oscillating force at each wheel/track contact, and this is transmitted to the ground at each sleeper/ground contact.
Can train vibrations damage house?
No, train vibrations do not cause cracking in houses (sheetrock, stucco, etc) that are more than 20 to 30 feet away from the tracks.
How do train tracks not buckle?
As most track is made up of long pieces of rail that are stretched and welded together, there is much less chance of buckling in very high temperatures because there is reduced compression.
Why do train drivers honk?

Why are trains so noisy?
Roughness and irregularities on the wheel and rail surfaces are a source of noise and vibration. Rail joints and squats on the rail cause a familiar clickety-clack sound as train wheels roll over them.
Why do UK trains tilt?
British Rail invested heavily in tilting-train technology to overcome the limitations of a rail network located in space-constrained built-up areas. Italy's Trenitalia and the Japan National Railways have used tilting technology to speed express trains on conventional tracks through mountainous terrain.
How far away can you feel a train vibration?
It is suggested in general that vibrations are not noticeable at distances over 300 m from the railway [23].
Why do trains honk before going into a tunnel?
If for no other reason, the horn can alert those folks to get to safety. either to alert people when they enter the tunnel(like MOW, or trespassers) or in some cases, to be friendly at kids(or railfans) at the tunnel entrance.
Can you hear a train before it hits you?
“People assume that trains are loud, but that assumption is based on the fact that when a train's gone past them in a station it's noisy. That's because the noise a train makes is mainly projected to either side. When trains are moving directly towards you they are barely audible–until it's too late.”
