Titanic by numbers

At 883ft long, the Titanic weighed more than 46,000 tonnes and was carrying more than 2,200 passengers.

More than 1,500 of them died when the vessel struck an iceberg and sank while crossing the Atlantic on its maiden voyage, having set out from Southampton.

Built in Belfast by Harland and Wolff, the Titanic used 825 tonnes of coal a day and was capable of speeds of up to 26mph.

The maiden voyage to New York set back passengers travelling first class as much as £875 - the equivalent of many thousands of pounds now.

Only one of the children in first class died and all of the 24 children in second class survived, yet 66% of the children in third class were lost.

As many as 140 of the 144 women in first class were saved but 54% of women in third class perished.

A Swedish mother and her four children all aged under 10 died, while some bodies were not recovered for a month.

The eight-man orchestra, that gallantly played on until the end, all died, as did the ship's captain Edward Smith.

Maritime regulations at the time required vessels more than 10,000 tonnes in weight to carry only 16 lifeboats, plus rafts and floats.

The Titanic had 20 lifeboats but this was enough for only 1,180 of the 2,200 people on board.Having struck the iceberg at 11.40pm on April 14 2012, the ship finally sank at 2.20am.

The vessel Carpathia arrived at 4.10am and spent more than four hours rescuing people.

The British Board of Trade inquiry into the disaster took place from early May to early July 1912.

The Titanic wreck was located around two-and-a-half-miles down at the bottom of the Atlantic by an American-French expedition in 1985, which confirmed that the ship had split apart.

Hundreds of artefacts, including - somewhat amazingly - undamaged crockery, have been recovered from the wreck and have been displayed at exhibitions.

Among those who died were American millionaires John Jacob Astor IV and Benjamin Guggenheim, Canadian railway president Charles Hays and Sidney Leslie Goodwin, an infant whose identity was established only in 2007.
