secondarycoupled
Secondary coupling, also known as secondary coupled or UIC coupling, is a type of coupling used to connect railcars together. It is a standard type of coupling used in many countries, especially in Europe and Asia.
The secondary coupling is used in conjunction with the primary coupling, which is typically a Buffon-UIC coupling.
Secondary couplings are typically designed to meet the standards set by the International Union of Railways
The design of the secondary coupling is often similar to the primary coupling, but with fewer steel
Overall, the secondary coupling is an important component of modern rail transportation systems, providing a safe
