The engines were powered by boilers
The Titanic had funnels to get rid of low pressure steam after it had been used to drive the engines.
The RMS Titanic used 2 triple-expansion steam engines, each weighing 1,000 Tons (2 million pounds each). Source: Titanic-Titanic.com (see link below)
The engines did not fail. Unfortunately they drove Titanic into the iceberg with resounding success.
Nobody reversed the engines anytime during the night Titanic was struck, but briefly, the engines were turned on.
Engine, as in the steam engines that powered the Titanic.
Coal burning furnaces which produced steam to drive expansion steam engines.
Titanic was steered (unsuccessfully) to avoid the berg but the engines were not reversed.
Two triple expansion steam engines and an exhaust turbine
Non, because Titanic didn't use fuel. She used coal, instead of fuel.
Reciprocating engines are very big engines. Instead of a motor just spinning the propeller, electric arms would move up and down circling around the propeller line spinning it. These kind of engines were used on the titanic.
The three Olympic-Class vessels, including Titanic, were designed By Alexander Carlisle.
Train engines today are usually powered by diesel fuel, which is burned in conventional internal combustion diesel engines, which turn electric generators, which produce electricity that is used to drive electric motors that drive the wheels.
