Why it matters
The 1804 opening marks an early steam-locomotive milestone and 1869 marks major railway and canal connections. Rail and steam developed through many experiments and regional systems; sail, road, river and animal transport continued. The selected dates do not mean a completed worldwide network.
Science Museum Group transport collection ↗Faster transport supported migration, mail and markets, but also troop movement, extraction, indenture, settler expansion and dispossession. Workers who built and operated these systems, and communities whose land they crossed, belong inside the history of engineering.
