When a train suddenly starts moving forward, the passenger standing in the compartment tends to fall backward is an example of inertia of rest. The reason behind this is the lower part of the passenger's body is in close contact with the train.

When the train stops, there is no force acting on the object (passenger), so he will remain in motion. This is why when suddenly the train stops, due to the law of inertia or Newton's first law of motion, the passengers are pushed forward.
This is due to inertia. Inertia is a property of matter by which it continues in its existing state of rest or of uniform motion unless acted upon by a net unbalanced external force.
And each coach has a large static inertia. Because of this combination, the coaches far away from the engine get a pull much after the engine has overcome its static inertia and attained a non-trivial momentum. Also, given the coupling slack, the pull is sudden.This causes the jerk.
This is due to inertia. When the speeding bus stops suddenly, lower part of the body comes to rest while the upper part of the body tends to maintain uniform motion. Hence, the passenger's are thrown forward.
In the United States it is the law, same as if involved in a vehicle to vehicle accident or accident with a pedestrian on the road is the same on the railroad, the law and railroad operating rules always require stopping the train after an accident or incident and rendering aid to injured people.
When a bus takes a sharp turn, the person travelling in the bus tends to be thrown outwards towards the window. This is due to inertia of direction of the passenger.
When a bus takes a turn, the centrifugal force felt by the passengers, is directed opposite to the direction of the turn. Hence, when a bus takes a right turn, the passengers inside the bus seem to lean towards left.
Rail squeal is a screeching train-track friction sound, commonly occurring on sharp curves. Squeal is presumably caused by the lateral sticking and slipping of the wheels across top of the railroad track. This results in vibrations in the wheel that increase until a stable amplitude is reached.
The horn alerts people that a train is approaching a railroad crossing. It can also be used to warn animals or trespassers in our right-of-way along a section of track.
