The Laidley Valley Branch Railway was opened on 19 April 1911 and covering a mere 11 kilometres, the Laidley Valley Branch Railway was one of the shortest in Queensland, Australia.
Branching from the Main line at Laidley and passing through Cooper’s Hill, Goothenda, Paree and Kullee, it terminated at Mulgowie. The line was the culmination of 30 years agitation to access the rich agricultural area along Laidley Creek.
The line was never profitable, servicing an agricultural valley with a low population density. The initial twice-daily service was reduced to once daily in 1918 and reduced again to a twice weekly service in the 1930s. A possible extension to Thornton did not materialise, and once an all-weather road was constructed the uneconomic branch closed in 1955.
