 The rebuilt locomotive emerged from Ashford works as No.1822 in October 1931.Although the N1s displayed little overall improvement over the N class, they proved ideal for the gauge-restricted Hastings route, where their narrower profile allowed them to operate through narrow bridges and tunnels, and their power enabled them to haul heavier trains than the predominant ex-SECR 4-4-0 and 0-6-0s.
