The main building, attached to the museum, contains a library and a collection of railway items such as caps, miniatures, and machinery.

In 1981, the centenary of the commercial rail line between Barcelona and Vilanova, the creation of a Railway Museum in the old engine shed was proposed.

The national Spanish railway operator (RENFE) and the autonomous government of Catalonia initially led the project.

The collection also includes diesel and electric locomotives, coaches, a Bogie type Harlan, a signal bridge, and an original interlocking lever frame table used in the Barcelona central railway station.

The museum's library contains more than 6,100 volumes in its catalog, including works on trains and vehicles, rail traffic documentation, history and legislation, statistics, and infrastructure.
