Railway bogies, suspension, wheels, and axles form the important components of rolling stock. The bogie framework fitted with the wheels, suspension, and axles supports the rail body and provides stability to the structure while improving the ride quality.
A railway bogie is a crucial part of the drive system and guidance mechanism and is being continuously advanced to improve the railway vehicle’s speed, safety, and passenger experience.

Bogies are a complex structure in a railway vehicle containing the drive systems and brake systems. Bogies are classified according to their configurations in terms of the number of axles and the structure of suspension. The two-axle bogie is the most common type.
Powered bogies are fitted in locomotives, mass transit vehicles, and high-speed trains. For improved stability in high-speed operations, the weight of the un-sprung bogie parts is reduced using hollow axles and by incorporating aluminium alloys into the axle and gear boxes.
The efficiency and safety of railway vehicles depends on the bogie design and maintenance practices.
