Started as a base for the calculation sheet, but this report eventually lead to a comparison between two engines of two axle drive and another two with three axle drive. However this was only to prove the results and calculation reliability. In this comparison and set of results major and principal characteristics from the engines are seen. In addition, a set of upgradable characteristics are considered and even highlighted i the beginning of the report in the Theoretical Considerations. In spite of all the limitations of no-dimensional method, it was possible to have a set of promising results, even considering the basic set of calculation in it mix.
