WILLIAM Cook Rail has acquired the coupler business of Sheffield Forgemasters Engineering Ltd, and is relocating it to the William Cook Rail headquarters in Leeds.

The principal products of Sheffield Forgemasters are the AAR Type F coupler widely used on freight stock, the Type H Tightlock used on multiple-units and hauled passenger stock, and the Willison coupler used extensively on industrial railways.

Knuckle coupler design, manufacturing and refurbishment is the main business of William Cook Rail, and the acquisition will expand its range of services.
