Designed in the late 1930s, these enormous steam giants were built by the American Locomotive Company (ALCO) and operated from 1941 to 1962. 25 Big Boy locomotives were constructed in two batches, with road numbers 4000–4019 and 4020–4024.\u003c\/p\u003e\n\u003cp\u003eBig Boys feature a 4-8-8-4 articulated wheel arrangement, with four leading wheels, two sets of eight driving wheels and four trailing wheels supporting a huge firebox. This design allowed the massive locomotive, over 132 feet long and weighing well over a million pounds with its tender, to negotiate curves despite its size. With drawbar power up to around 7,000 hp and incredible tractive effort, the Big Boy could haul trains of 3,600 tons or more unassisted over mountain grades and sustain speeds of over 80 mph on level track.\u003c\/p\u003e\n\u003cp\u003eThese locomotives worked primarily between Ogden, Utah, and Cheyenne, Wyoming, handling heavy freight throughout World War II and the post-war era. As diesels replaced steam in the 1950s, Big Boys were gradually retired, with the last revenue service run in 1959.\u003c\/p\u003e\n\u003cp\u003e\u003cem style=\"font-family: -apple-system, BlinkMacSystemFont, Roboto, sans-serif; font-size: 0.875rem;\"\u003ePlease note this item is located at our online warehouse rather than our shop.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Marklin","offers":[{"title":"Default Title","offer_id":57061392351607,"sku":"39400","price":1950.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0773\/5957\/9423\/files\/18b0097fe501401055bcaf0898bc316e1765890005.jpg?v=1777615177","url":"https:\/\/footplate.co.uk\/products\/marklin-ho-gauge-39400-union-pacific-4000-big-boy-steam-locomotive-ac-sound","provider":"Footplate","version":"1.0","type":"link"}
