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.
