These specially reinforced ARP (Air Raid Precautions) signal boxes featured substantial construction, primarily to protect the locking room gear from bomb blasts during air raids in World War II. A number of similar signal box designs were still to be found around the rail network until quite recently, due to them being difficult to demolish!
Based on the LMS-designed example at Town Green, Ormskirk the Ratio kit faithfully replicates the prototype and builds into a sturdy, if not bombproof, model. All moulded parts are produced to a high standard and in base colours. Kit requires painting and light weathering to create the model pictured above.
