Why the passengers get a jerk when the train stops?
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.

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.
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.
Trains have the right-of-way because they cannot quickly stop for a motorist at crossings or for trespassers on the tracks. The average freight train, traveling at 55 MPH, takes anywhere from 1 to 1½ miles to stop. Traveling at the same speed, the average automobile can stop in only 200 feet.

Basically the bullet train remains in a constant state of motion to save time and energy typically spent accelerating and decelerating. Prior to the train's scheduled arrival passengers enter a “connector cabin” situated at the station.
By the time a train operator sees you, it is too late to stop the train in time. An oncoming train is moving faster and is closer to you than it appears. Similar to an airplane traveling at 150 mph that appears to float onto the runway, it's hard to determine a train's speed and distance from you.
The middle of the train is by far the safest for persons. The National Transportation Safety Board does not release comprehensive data on where victims were sitting during fatal train accidents, though some details are available in individual investigative reports.
Fact #2: Railroad Tracks Are Private PropertyWalking on train tracks may seem like fun, but it's actually very dangerous, not to mention illegal. All train tracks are private property, so pedestrians should never walk on or near them.
The Trans-Siberian is the longest passenger train in the world and travels across China, Mongolia, and the famous, beautiful Siberia. Have you ever considered cruising over 10,214 km for seven days and 20 hours, crossing two continents and a whopping eight time zones?
This is because of inertia of motion. The part of our body, which is in contact with the bus, changes the direction of motion. However, the rest of the body tries to move in the same direction as before because of inertia of motion. Q.
