How is air supplied to the front bellows?

Air is supplied to the front bellows through a tee connection, which allows for efficient distribution of air throughout the system. In a typical setup, the tee connection serves to split the airflow to multiple points, ensuring that the front bellows receive the same pressure and volume of air as the rest of the system. This method is especially beneficial in maintaining consistent operation of the air suspension or braking systems.

While other methods of supplying air could involve direct sources or specialized components, the tee connection specifically highlights the need for balanced air supply, which is critical to the proper functioning of the bellows and related mechanisms. This setup is often preferred in train operations because it simplifies design and ensures reliability in maintaining the necessary air pressure for safe and effective operation.
