This kit has a foot print of 82mm x50mm x105mm high. It’s called Ultimo St signal box and it sat at the end of Ultimo St Sydney and helped control Sydneys Darling Harbour Goods Yard. Although NSWGR built many of these signal box all across the state. I have even seen one sit at the bottom of the old Lithgow Zig Zag. Our kit is the first to come with lever frames included. A electrical kit is also available to bring your signal box to life. It is amazing what some lighting and a track plan do to a model.
