John Brown's railway was a line constructed in the Rotherham area of South Yorkshire, England, in order to link Silverwood Colliery to staithes situated alongside the River Don. The line, along with the collieries, became the sole property of John Brown & Company of Sheffield, in 1910, giving the line its local name.
John Brown and Company were also the owners of other collieries in South Yorkshire, including Rotherham Main, which was served by a Great Central branch line.
