Why did railroad leaders consolidate their lines in the 1880s? To reduce competition and increase efficiency. To keep from becoming too big too quickly. To ensure vertical integration. To increase rapid constitution of railroad lines.

Some reasons why railroad leaders consolidated their lines in the 1880s include:

1. To reduce competition and increase efficiency: By consolidating their lines, railroad leaders could eliminate duplicate routes and services, streamline operations, and reduce costs. This allowed them to control pricing, increase profits, and dominate the market.

2. To keep from becoming too big too quickly: Consolidation allowed railroad companies to grow strategically and avoid overextending themselves financially. By merging with or acquiring other lines, they could expand their networks more gradually and control their growth.

3. To ensure vertical integration: Consolidation allowed railroad companies to vertically integrate their operations by controlling the entire supply chain, from raw materials to transportation to distribution. This allowed them to increase their market power and capture more profits.

4. To increase rapid construction of railroad lines: Consolidation enabled railroad leaders to combine resources and expertise to quickly build new lines and extend existing networks. This facilitated the rapid expansion of the railroad industry and facilitated economic growth and development.
