Coyote is a Light Blue GWR 57xx Tank engine
Coyote is based off the GWR 5700 Class Pannier Tank Engines. Originally Designed by Charles Collett, a staggering 863 5700's were built between 1929 and 1950. The majority of 5700's were built at the GWR's own Swindon Works, though the first 50 locomotives (5700-5749) were built by the North British Locomotive Co., in Glasgow Scotland and would go on to produce 50 additional members of the class, with additional locomotives being built by Armstrong Whitworth, W.G. Bagnall, Beyer, Peacock, and Co., Kerr Stuart, and the Yorkshire Engine Co. The 5700's (And their various sub-classes) were used for various duties including shunting, pilot work, and medium-sized goods trains across the GWR's System, and on several branch lines. Following the introduction of the Modernization Plan in 1955, and the closure of several branch lines (and the introductions of Diesel Shunters), the Panniers began to be withdrawn. Interestingly, 19 of the Panniers were sold to London Transport following withdrawal by BR for Engineering and Ballast Trains. All off the 5700 Class Panniers were withdrawn by 1966, but 3 of the London Transport Panniers would last until 1971. Happily, 16 Panniers survived into Preservation, including 10 from the London Underground and an additional 6 from the scrapyard.
Coyote, for the most part, is fairly similar to his basis, though he lacks the Belpaire firebox that his basis has. Duck is another member of this Class!
