During the Industrial Revolution, any number of innovations came about that improved the standard of living for people in industrialized societies.
One of these innovations was the invention of the train. This allowed people to travel farther and more easily than ever before. More importantly, perhaps, it allowed goods to be moved quickly and relatively cheaply over land. This made all sorts of things cheaper than they had been before.
Another innovation was the "spinning jenny" (and cloth-making equipment). This made it so women no longer had to spin their own thread and make their own cloth. This made clothing cheaper.
During the second phase of the Industrial Revolution, perhaps the most important innovation was electric power. This gave people electric lighting and eventually the power needed to run all sorts of appliances.
