This book explores the variety of traditional signalling used in the BR era, from pre-Grouping infrastructure and mechanical signalling to BR-built signal boxes prior to the conversion to colour-light signalling. The principles of signalling operation are also explained. Author Robert Hendry provides rare and previously unpublished images to present a fascinating insight into traditional signalling on British railways.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e: 306g\u003cbr\u003e\u003cstrong\u003eDimension\u003c\/strong\u003e: 164 x 233 x 13 (mm)\u003cbr\u003e\u003cstrong\u003eISBN-13\u003c\/strong\u003e: 9781398113978\u003c\/p\u003e","brand":"Robert Hendry","offers":[{"title":"Paperback \/ softback","offer_id":47060642070778,"sku":"9781398113978","price":11.41,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0522\/4297\/2845\/files\/1737138926912_book.jpg?v=1737192636","url":"https:\/\/shulphink.com\/products\/traditional-signalling-on-british-railways-9781398113978","provider":"Shulph Ink","version":"1.0","type":"link"}
