Stonier, who had previously been the Works Manager at the GWR Works at Swindon realized that there was a need for larger locomotives and using his experience gained at Swindon took inspiration from the GWR Hall Class locomotives. Both the Black 5 and Hall locomotives shared similar cylinder arrangements, internal boiler design and had 72 inch diameter driving wheels. Consequently, the 'Black Fives' with their 6 feet driving wheels could attain speeds of around 90mph, making them ideal for passenger traffic. Initially twenty were ordered from the Crewe Works and a further eighty from the Vulcan Foundry, with the numbering starting from 5000.The first locomotive to be completed was actually engine No. 5020 in 1934 and was built at the Vulcan Foundry, while locomotive No. 5000, the first Crewe built example did not emerge until 1935. The original examples were built dome less with straight throat place boilers and a low degree superheat.
