What are the three main parts of a hitch?

The correct answer identifies the three main parts of a hitch as the diagonal strut, vertical strut, and top plate. These components are crucial for the proper functioning of a hitch, as they contribute to the stability and strength necessary to connect a railcar to another vehicle or railcar.

The diagonal strut provides additional support and helps distribute the load evenly, preventing excessive flex that could lead to structural failure. The vertical strut supports the overall framework of the hitch and helps maintain alignment during operation. The top plate serves as the primary interface where connection points are made, providing a durable surface for attachment.

This combination of parts ensures that the hitch can effectively manage the stresses encountered during rail operations, promoting safety and reliability. Understanding these components is essential for anyone involved in rail mechanics, as they play a significant role in the hitch's functionality.
