Different designs require different solutions. This general statement is applicable for selecting the adequate primary spring. Therefore you will certainly find a variety of steel and rubber or rubber-to-metal bonded primary springs in your fleet.

Except for LRVs the air spring is the common solution for a secondary suspension between bogie and car body. As an option steel and or layer springs may take this function as well as hydraulic solutions. The biggest advantage of the air spring is its unbeatable reliability, the height adjustment of the car body and the excellent comfort for the passengers. Unlike the primary springs air springs generally are a combination of different springs. For maintenance you may consider them independently but should also consider the complex combination of the parts involved.

Transmission of power between different components of the flexible bogies but also between the bogies and car bodies is realized by using different rods, bushes, and buffers.
