Notes: The design of these engines was copied closely from the Bury, Curtis & Kennedy 6ft 2-2-2 class of 1848, but with plate frames, bigger boilers and 7ft driving wheels. The first twenty were built by Sharp in 1851-1853, and were promptly nicknamed 'Bloomers' during the wild excitement aroused by Mrs Bloomer's advocacy of trousers for women. The name stuck and was adopted officially. To distinguish them from the smaller version of 1854-1861 they later became known as Large Bloomers.

The engines were very successful and another twenty were built in 1861/2: five by Sharp, five by Kitson, and ten at the L&NWR's Wolverton Works.

There were detail differences among the original engines, especially in the boilers. In the 1860s and 1870s most of the class were rebuilt with Crewe boilers containing 178 tubes of 1⅞in diameter. The original tenders had a well below the footplate which contained 500 of the total 2000 gallons of water, but the wells were removed by Crewe; the rebuilt tender contained 1700 gallons and was fitted with water pick-up gear.

All the Large Bloomers were given names in 1872. Scrapping began in 1876, but the longest-lived lasted for 34 years, and the last one went in November 1888. It was the last ex-Southern Division engine on the L&NWR.
