This tank wagon for transporting petroleum-derived fuels was part of the project that CAMPSA developed in 1957 to build 500 tank wagons with an average capacity of 22,500 liters, equipped with vacuum brakes featuring an S.A.B. brake rigging regulator, which allowed for the formation of dedicated trains that could run across the entire railway network, resulting in increased transport efficiency and a notable improvement in distribution.
It was operational until the early 1980s, when it was converted into a hauled wagon by means of a winch connected to an electric motor for shunting operations at the CAMPSA facilities in Tarragona, where it remained in service throughout that decade until it was taken out of use.
In 2016, the Compañía Logística de Hidrocarburos (CLH), the successor to the previous company, donated it to the Railway Museum in Móra la Nova. Its transfer required the preparation of a very complex logistics operation because, although the vehicle looked somewhat good, it had been out of service for years, and due to the weight of the ballast it carried, the wheels had become welded to the track. It was then transported by road to the Museum's headquarters, where throughout 2017 and 2018 it was functionally restored and now looks as it did originally.
