RENFE, 2-part set postal cars DGDC-3000 in olive green livery, Era IV.

The postal cars of series 3000, belonging to the General Directorate of Post, are an evolution of the UIC-X bodies that have proven themselves in the cars of series 8000. They were manufactured in the late 1960s and represented a significant renewal of the postal fleet. They offered more comfort, more space, and more functionality for the personnel responsible for sorting and organizing mail and small packages.

Equipped with Minden-Deutz bogies, they, like the other cars of this type, were in service until the 1990s when Correos ceased rail operations in Spain.
