What specific demands pushed engineering beyond stationary mill needs for locomotives?

Answer

High power-to-weight ratio and sustained high-speed operation

The application of steam power to transportation, especially rail, required engines capable of moving significant loads at high speeds while minimizing the engine's own mass, forcing developments in thermal management and safety beyond stationary needs.
