Moreover, the boats, trolleys, trains, automobiles and even planes with electric motors were invented. The locomotives started experimenting the forms of power in the 1920s.
As an illustration, we can see that there were improvements in the transportation technology history in the form of the electrification of trucks and locomotives. Back in the day people were able to enjoy the benefits that diesel engines brought.
Hence, the transportation technology history in the period of 1900-1950 is showing us that the ships started becoming more efficient due to the coal replacement. The ships began operating on oil.
Therefore, the commercial boats, as well as the pleasure craft boats, were powered by internal combustion engines.
As a matter of fact, the vehicles that were invented in this period of the transportation technology history were primitive. In fact, it was in 1919 when the self-starting engine made automobiles and truck easier to use.
