■ True to origianl livery and lettering

The term heavy duty flat wagon is nowadays only known colloquially, as you can no longer find its equivalent in the international classification of goods wagons according to the UIC. It is a commonly used designation to describe a relatively short flat bogie wagon with a flat floor to carry heavy loads such as machinery, tanks or slabs.
