A point drive unit (10) is disclosed for driving railway points to move via a connecting means of the points located generally centrally between two of the rails (3) of the railway track. The unit comprises a housing (11, 12) adapted to be installed between the two of the rails; a cylinder (18) enclosing a piston (19) which is moveable for driving the points, the cylinder being mounted within the housing at a location laterally offset to one side of the housing; control means mounted within the housing at a location laterally adjacent the cylinder for controlling the supply of fluid to the cylinder to control the movement of the piston; and an offset coupling (20) for coupling the piston to the connecting means so that the piston is laterally offset from the connecting means.
