It was one of the most important British liner routes of all - the
express run from Southampton to the South African Cape. Carrying
passengers as well as cargo, including the all-important mail, it was a
byword in travel - 'every Thursday at 4', as one of the big Union-Castle
liners set off for Cape Town and beyond. By the late 1950s, these mail
ships included the Arundel Castle, Carnarvon Castle, Winchester Castle,
Athlone Castle, Stirling Castle, Capetown Castle and two post-war
sensations, the Edinburgh Castle and Pretoria Castle. Three new liners
arrived in 1959, the last great ships built for Union-Castle. They were
Pendennis Castle, Windsor Castle and Transvaal Castle. The route was not
just to the Cape - for Union-Castle also offered a service down the East
coast of Africa and a round-Africa route too. In 1977, with the mail
contract and passengers lost to the jet and cargo to container ships,
the service ceased in October that year and Union-Castle was no more.
