The RMS Olympic was a White Star Line ocean liner, the lead ship of the Olympic class and the older sister of the Titanic. Launched in 1910, she served on the transatlantic route for more than two decades, including wartime service, before being withdrawn and scrapped in 1935. Recordings of her distinctive steam whistle survive as a rare link to that era of large liners. Online, the clip is shared by maritime history fans and editors who want an authentic period ship sound rather than a modern horn.
