Yes, pretty much. There were three sister ships, Olympic (1911), Titanic (1912) and Britannic (1915, keel laid 1911). Britannic ended up serving only as a hospital ship during WWI, and was sunk during one of her missions. Olympic had a long and successful career, making her last crossing in 1935, and was eventually scrapped.
My grandfather and his brother tried to book passage on the Titanic but it was sold out so instead they came over to Canada later that year. Of course, being Irish immigrants, they would have been in the steerage section and likely would have perished.
Yes but even this ship was plagued with trouble though know as "Old Reliable."
She had a collision with the HMS Hawke off the Isle of Wight on September 20th 1911 ironically Captained by Edward Smith of the Titanic. Pulling resources from the Titanic to fix the Olympic and delayed Titanicís maiden voyage from 20 March 1912 to 10 April 1912.
Then she had a second collision, this time with the Nantucket Lightship 117 on May 15, 1934 and the lightship sank with 4 casualties I believe.
The Olympic also has the distinction of being the only merchant ship to sink an enemy warship during the war when she rammed the German submarine U103 on 12 May, 1918
