slats and a steel and timber frame, was placed back-to- back facing each track. Dividing each row of seating were metal ribbed screens. Fitted to each steel column and under each beam were panels framed in steel and filled with glass above the seat level and sheet steel below. The other narrower platform necessitated smaller butterfly-roofed awnings be built there. They were essentially the same construction as the larger ones with only three bays, two of which were given over to seating. The subway system with its street ramps and stairs to both platforms was constructed with reinforced concrete. In June 1958 the Commissioner reported that new concrete and brick station buildings were under construction at Sherwood, Graceville, Chelmer, Indooroopilly and Auchenflower, and subways were completed or under construction at Graceville, Chelmer, Taringa and Nundah. The Graceville complex of station building, awnings and subway, and enlarged and raised platforms at a cost of , was the first of these new stations to open in mid-1959. Chelmer, with an identical layout of one building and four awnings, all butterfly-roofed, opened shortly afterwards. Milton, also drawn by Jan Kral was built in 1960. At the time of its completion in mid-1959, Graceville Station featured in a number of local newspaper articles where it was described as one of the most modern in Australia. The Commissioner also chose to feature a photograph of it in his annual report. Architect John Egan published an article on the new station designs in the Architecture in Australia journal in June 1961. All the new station buildings constructed in the 1950s and early 1960s for the quadruplication and electrification projects employed a Modernist idiom, but only the platform stations at Graceville (1959) and Chelmer (1959) on the Corinda line, and at Nundah (1960) and Eagle Junction (1963) on the northern line, were designed with butterfly roofs. Similarly designed, but with flat roof profiles were Sherwood (1960), Indooroopilly (late 1950s), Toowong () and Milton (1960). Taringa (mid-1950s), Toombul () and Wooloowin (1960) were butterfly-roofed overhead stations; Corinda (1960) was a flat-roofed overhead station; and Auchenflower () was a skillion-roofed overhead station. A standard plan was drawn up for Nundah and Graceville in 1955, but only Graceville and Chelmer were later constructed with the same pitch to their butterfly roofs. Nundah was given a flatter roof made with steel framing rather than reinforced concrete. In September 1960, the quadruplication
