Historian Liz McIvor explores how Britain's expanding rail network was the spark to a social revolution, starting in the 1800s and through to modern times.

A fast system of transportation shaped many areas of our industrial nation, from what we eat to where we live, work and play. The railways generated economic activity but they also changed the nature of business itself. They even changed attitudes to time and how we set our clocks! Our railways reflected deep class divisions, but they also brought people together and helped forge a new sense of national identity.
