S56 Class No. 84 was one of the last batch of ten locomotives built for the Great Eastern Railway, to Order P57, at Stratford in 1904 and incorporated many of the improvements made to the R24 Class in the 1902 Improvement Programme. No.84 is portrayed in the classic GER livery of Ultramarine Blue with Vermillion lining and shaded lettering, as it operated from Stratford Shed until being repainted into the GER’s ‘austerity’ grey livery in 1915.
