Ten years later, the company – by then, renamed Prussian-Hessian Railways – additionally required that signage lettering on railway platforms and station premises also be rendered according to the 1905 master template. This specification was published in a document known as Musterzeichnung ('master template', literally: 'pattern drawing') IV 44. The origins of DIN 1451 Engschrift ('condensed face') for hand lettering date back to 1905, when the Prussian state railways prescribed a standardized lettering style for use on all of its rolling stock. These were to be used in the areas of signage, traffic signs, wayfinding, lettering on technical drawings and technical documentation. It contained several standard typefaces for mechanically engraved lettering, hand-lettering, lettering stencils and printing types. In 1931, the DIN institute published DIN 1451.
