It is located to the west of the West Coast Main Line and the branch line to Folly Lane. The signal box is recorded in the National Heritage List for England as a designated Grade II listed building. It was built by the London, Midland and Scottish Railway (LMS) in the early years of the Second World War incorporating the specifications of the Air Raid Precautions (ARP), and was one of the first of such signal boxes to be operational. ==History== The signal box was designed and built by the London, Midland and Scottish Railway (LMS) to replace an earlier timber signal box that stood on a gantry. It was opened in January 1940. In the years approaching the Second World War, and in the early years of the war, precautions were taken to protect existing signal boxes from enemy bombing. In addition, some new signal boxes were built according to the specifications of the Air Raid Precautions (ARP); these were designed to protect against damage by blast rather than from a direct hit. The specifications included brick walls thick, flat roofs of reinforced concrete thick, and metal window frames. The use of timber was reduced to a minimum to reduce the risk of fire. The LMS built over 50 signal boxes between 1939 and 1950 incorporating the ARP specifications, and the Runcorn box was one of the earliest of these signal boxes to have been operational. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Runcorn signal box」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
