The Pennsylvania Railroad no. 1320 was a single experimental passenger three-cylinder compound 2-2-2-0 locomotive purchased by the Pennsylvania Railroad in 1889, based on the London and North Western Railway's (LNWR) Dreadnought class, designed by Francis Webb. As the railway's Crewe Works (which had built the Dreadnought classes) was not legally allowed to sell its locomotives, 1320 was instead constructed by Beyer, Peacock & Company in Manchester to the Dreadnought's specifications.^[1]
