European architects to Queensland – professionals like Karl Langer who occupied a role with the railways from 1939 until 1946 – but also a post-war flow of architects from Britain and Europe who came to Queensland in search of work and brought with them the architectural ideas and training that were driving forward the large task of post-war reconstruction and housing provision being undertaken in their countries of origin. Under Principal Railway Architect John Sidney Egan, new station designs were prepared for the quadruplication project. An overall concept for the form and structure of the station buildings was established, but the designs were non-standardised, and took account of platform width, which varied from station to station. Architect Jan Kral was responsible for the Graceville and Chelmer designs and signed off on the drawings for Sherwood station as Acting Principal Architect. He was born in Poland and studied at Stuttgart University after the war. He came to Australia in 1950 and was employed by the Queensland Railways the following year, initially as a draftsman, becoming a Senior Architect by 1958. While the designs were all somewhat different, they shared a form derived from a long, thin building, rectangular in plan and made with a regular procession of columns, surmounted by a butterfly roof that cantilevered over each platform side to shelter waiting and alighting rail passengers. A number of standardised plans for Railways Department butterfly-roofed awnings were developed and used between 1949 and 1960, many having been designed by Bevis Thelwall. A common palette of materials including reinforced concrete, steel and exposed brickwork was used. The steel work was all prefabricated at the Northgate workshops. Graceville Station was the first of these station fit-outs to be completed within the quadruplication project between Corinda and Roma Street. The main building at Graceville had a butterfly roof formed with a reinforced concrete slab lined with bituminous felt and supported on ten pre-cast, reinforced concrete beams that cantilevered off a continuous lintel resting on ten brick piers. A range of materials were used to fill the gaps between the brick frame: including orange-coloured face brick, screened openings, some small sections of render and various aluminium-framed windows. On either side of this building, two wide butterfly-roofed, steel-framed shelters with built-in seating were erected. Each was made up of four sets of steel columns and cantilevered steel tapering I-beams bolted together. The seating, made with timber
