Fast moving trains how it is brought to halt (non emergency)?

Question

even pulling chaine, brings train to halt but sudden halt is not possible ,in a graded lose of speed -- how --to prevent jolt, shifting from the tract and safe halt

Answer 1

On a passenger train, if you pull the chain it will cause an emergency stop.  That means the brakes hit as hard as possible.  It might "feel" smooth to you, but that's only compared to an automobile right?  Autos are much lighter and grip the road much better.  It probably won't derail the train but it probably will damage the train.  Usually the wheels lock up and skid a big flat spot onto em, which is expensive to repair.

Normal stopping takes special skill by the engineer.  It is easy to jerk a passenger train around, even a modern one with tightlock couplers.  One common technique is power braking, where he overlaps both power and brakes to smooth the transition.

On freight trains, skill is essential. The engineer he has to manage "slack" in the couplers - over many cars it adds up, and the force of it bunching at once can damage freight or even derail the train.  This train is probably partly loads and partly empties, scattered throughout the train, and empties brake harder than loads.  It is quite difficult to "get it right".   That is one reason the American railroads stopped using cabooses - there were many crew injuries in the caboose from slack.

Answer 2

Brakes are applied about a mile before the stopping point. As the train nears the stopping point the brakes are eased off and then on again slowly to bring the train to a smooth halt.

Warning signals are placed to give sufficient time for the driver to apply the brakes smoothly before reaching the stop signal.

Answer 3

I will assume you are talking about fast stops on passenger trains.

There is no or very little "jolt" which comes from slack or movement between cars in the couplers and draft gears.

Couplers in passenger trains are "tight lock:" couplers with no movement between them so there is no sudden change of velocity, either accelerating or decelerating.

In addition passenger trains almost always have "blended braking" which as the name applies is a type of braking action that combines the engine or "dynamic" braking with the air brakes on the train.

Passenger trains can slow down amazingly fast, especially compared to freight trains.

A full stop from 60 MPH can take as little as 1/4 mile.

Train engineers undergo a lot of specialized on the job training, whether it be in freight or passenger service to avoid exactly what you are referring, jolts and shifting and keep goods and people moving safely.

Interesting question, shows you are thinking.
