3-part set of 2-axle refrigerated cars Hgb (2 x without brake van, 1 x with), "UK" vehicle limit line, in white livery with red stripe of the FS, Era IIIa

In 1931, the FS began the construction of a large group of refrigerated cars of the Hgb type, which were intended for the transport of perishable food to Great Britain and were derived from the typical Italian "slanted roof" refrigerated cars that were already well-known throughout Europe at that time.

In addition, the refrigerated cars of English design were also easily recognizable by their livery, as they featured a visible red band on the sides and the large logo with the anchor, indicating the possibility of a ferry.
