Why do trains jerk when they stop?
Velocity is the change in position, acceleration is the change in velocity, and jerk is the change in acceleration. It's called 'jerk' because you perceive a jerk when acceleration changes rapidly. the faster you stop the more the jerk will be.
How long can a train engine last?
As more new locomotives are being added to the fleet, the older ones are moved to other less demanding tasks, like moving railcars in a hump yard. Many locomotives can last 30–40 years, depending on the maintenance done on them. Our GG1 Lasted 41 years, but many of the steam locomotives were retired early.
