Answer:
Since the 18th century, the mechanization allowed for each mode to experience an evolution in motive methods and vehicles. New engine technologies offer the ability to be used across several modes with specific adaptations. The first most meaningful innovation was the steam engine that improved the performance of the maritime and railway modes at the end of the 18th century. The bulk of a steam engine made it impractical to be applied to road transportation.
The internal combustion engine (ICE) in the late 19th century brought the large-scale mechanization of transportation modes, especially road transport. It was followed by the diffusion of cars, buses, and trucks supported by vast highway networks. For rail, diesel locomotives replaced steam engines. However, the development of high-speed rail (HSR) relied on the electric motor due to its capacity to generate high speeds an internal combustion engine would be unable to.
