{"product_id":"colour-light-signalling-for-model-railwa","title":"Colour Light Signalling For Model Railwa","description":"Despite modern appearances, colour light signalling has been around since the 1920s and is just as full of subtle details and variations as ''traditional'' semaphore signalling.  The inclusion of a working signalling system within a model railway layout is technically challenging but adds realism and ''wow'' factor.  This new book contains a brief history of the development and deployment of colour light signalling in the UK; a basic explanation of how track design influences signalling design; an overview of the different types of point motor and, finally, descriptions of the different components that make up a signalling system and how these components are used and controlled.  It is an extensive guide to developing and adding realistic colour light signalling to a model railway layout.","brand":"MediaPlace","offers":[{"title":"Default Title","offer_id":57316508434814,"sku":"NW9781785006258","price":16.53,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/1379\/1261\/files\/9781785006258.jpg?v=1778652018","url":"https:\/\/mediaplace.com\/products\/colour-light-signalling-for-model-railwa","provider":"MediaPlace","version":"1.0","type":"link"}
