It was a classic symbol of the attitude towards speed and design in the 1930s, which saw increased competition to the railways from road and air travel. The LNER Board knew that they had to make travel between the major cities faster, comfortable and more reliable. High speed diesel services were starting to make an impact abroad and in May 1933, the German State Railways diesel-electric Fliegende Hamburger entered service, running for extended periods at 85mph.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eBy 1934, in the USA, Burlington Zephyr had reached 112.5mph during a longer 1,015 mile journey. Nigel Gresley, the LNER's Chief Mechanical Officer, travelled on the Fliegende Hamburger and was impressed by its streamlining, although he realized it was only efficient at high speeds. Gresley was certain that a modified A3 Pacific, with streamlining, could haul greater loads than the German or US locomotives, at the same speed or faster and a series of trials were conducted to confirm the Al's suitability.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWith the trials successfully completed, the LNER Board gave Gresley the go-ahead to create the \"Silver Jubilee\" streamlined trains, the first of the new streamlined A4s.The streamlining of the A4s' steam circuit, higher boiler pressure and extension of the firebox to create a combustion chamber made them more efficient than the A3 as they consumed less coal and water- especially later on when they were also fitted with a Kylchap double chimney. This improved their free steaming capabilities further. Their streamlined design not only made them capable of high speeds, but created an up draught of smoke, preventing obscuring the driver's vision that was such a major problem on the Class A4 engines. The story goes that during wind tunnel testing, after several unsuccessful efforts to get the smoke to lift clear, a thumbprint was inadvertently left on the clay model just behind the chimney. This succeeded in clearing the smoke and was incorporated into the final design.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eIn total, 35 A4s were built in four batches: 2509 - 2512, 4462- 4469, 4482 - 4500 and 4900 - 4903, between 1935 and 1938. They spent their working lives hauling express passenger services from King's Cross to Edinburgh via York and Newcastle. Although the Deltics proved worthy successors of the A4s on East Coast Mainline express services in the late 1950s, other diesel classes were unreliable. The A4s were kept in service until the mid-1960s, the last service under British Rail being the Aberdeen-Glasgow service on September 14, 1966.It was in July 1938 that 'Mallard' was recorded travelling at 126mph at Stoke Bank on the East Coast Mainline, snatching the record from the German railway by a mere 1.5 mph - a record that still stands to this very day.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eProduced under license for SCMG Enterprises Ltd © SCMGE.\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eWHAT'S INSIDE\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003e1x Locomotive Junior\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTECH SPECS\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/h3\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eItem Length - Without Packaging (cm): 29.1\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eItem Scale: 1:76 Scale 00 Gauge\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eFinish: Painted\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eColour: Blue\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eGauge: OO\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eDCC Status: DCC Ready 8 pin socket\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eClass: A4 Class\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eOperator:\u003cspan data-mce-fragment=\"1\"\u003e LNER\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eDesigner: Sir Nigel Gresley\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eWheel Configuration: 4-6-2\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eLivery: Blue\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eMinimum Curve (mm): Radius 2\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eNumber of Parts: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Hornby","offers":[{"title":"Default Title","offer_id":41249969733788,"sku":"R3371","price":310.49,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0585\/9095\/3628\/products\/r3371-mallard-railroad.webp?v=1727367362","url":"https:\/\/www.harveynorman.lol\/products\/lner-br-mallard-class-a4-loco","provider":"Hobbyco","version":"1.0","type":"link"}
