The 1950s began with relegation from Division A in 1950–51, but returned as Division B champions in 1951–52. The team repeated the feat in 1955–56 and 1956–57. Each occasion saw the team bounce back to solid finishes in Division A. Floodlighting was introduced at Shawfield in March 1954. The first opposition was Huddersfield Town in a friendly match. Huddersfield won 3–2. Cup success came readily in the 1950s. They won the Scottish Cup in 1954–55 and 1957–58 and were beaten semi-finalists in 1955–56 and 1959–60. They also reached Scottish League Cup semi-finals in 1956–57 and 1957–58, but lost on both occasions to Celtic.
