Healey Mills Marshalling Yard was a railway marshalling yard located in the village of Healey, south west of Ossett in West Yorkshire, England. The yard was opened in 1963 and replaced several smaller yards in the area. It was part of the British Transport Commission's Modernisation plan, and so was equipped with a hump to enable the efficient shunting and re-ordering of goods wagons. The yard lost its main reason for existence through the 1970s and 1980s when more trains on the British Rail system became block trains where their wagons required less, or more commonly, no shunting.
Facilities at the site were progressively run down until it closed completely in 2012.
