Why were railways often faster and more flexible than canals in the 19th century?

In the 19th century, railways surpassed canals as the dominant mode of transport because they offered a more extensive, integrated, and flexible service. While canals were often limited by their fragmented nature, small size, and slow speeds, railroads were far more efficient at covering vast distances and navigating terrain that would otherwise require complex and costly infrastructure, such as locks or inclined planes.12

The inherent limitations of canals included:
* Operational constraints: Canals were often restricted by their size and the number of locks, which slowed movement and limited the volume of cargo per unit.1
* Structural fragmentation: Unlike the integrated national systems developed by railways, many canal networks were disconnected and dependent on various intermediate carrying companies rather than acting as common carriers themselves.1
* Economic disadvantage: Modernizing canals to accommodate larger boats and reduce transit times required massive capital investment. Railways exploited these weaknesses through aggressive rate cutting, eventually forcing many canal companies to sell their assets or cease operations.1

Ultimately, railways provided a comprehensive transport solution that canals could not match in speed or adaptability.12
