The secondary suspension system is a suspension system that links the frame and the car body. It also includes springs, damping, and positioning mechanisms. At the same time, it also restricts the side turning of the car body. 

There are two main types of suspension systems used in trains, both of which are involved with springs. 


The primary suspension consists mainly of a normal spring damper system which supports the structural suspension of the carriage and entire train. These damper systems are present in every bogie existing between the axle box and the bogie.
