GWCU meaning in Regional ?

The Great Western Steam Ship Company operated the first regular transatlantic steamer service from 1838 until 1846. Related to the Great Western Railway, it was expected to achieve the position that was ultimately secured by the Cunard Line. The firm's first ship, Great Western was capable of record Blue Riband crossings as late as 1843 and was the model for Cunard's Britannia and her three sisters. The company's second steamer, the Great Britain was an outstanding technical achievement of the age. The company collapsed because it failed to secure a mail contract and Great Britain appeared to be a total loss after running aground. The company might have had a more successful outcome had it built sister ships for Great Western instead of investing in the too advanced Great Britain.
