{"product_id":"class-73s-mark-pike-9781802825442","title":"Class 73s","description":"Built in the 1960s, the Class 73s were primarily used on the Southern Region, owing to their ability to operate from either a diesel engine or third rail. Until the recent introduction of the Class 88s, they were unique in their electro-diesel ability. The initial 73s were either 73\/0 or 73\/1, depending on production run, and a select few were used on services to Gatwick in the 1980s and reclassified as 73\/2s. The last sub-class was the 73\/9s, which were converted by GB Railfreight and given new engines.   The Class 73s have never been the best-looking machines on the railway (some even nicknamed them  shoeboxes'), but the years of service these workhorses have provided certainly cannot be faulted. As the 73\/9s continue to find work around the UK, it seems they may be part of the railway scene for a long while to come. With over 220 images, this book shows off all the sub-classes of the 73s and their work around the country.","brand":"Key Publishing Ltd","offers":[{"title":"Default Title","offer_id":51058205688096,"sku":"9781802825442","price":13.59,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/2812\/7264\/files\/9781802825442.jpg?v=1781101319","url":"https:\/\/bookcorner.com\/products\/class-73s-mark-pike-9781802825442","provider":"The Book Corner","version":"1.0","type":"link"}
