Locomon

Locomon is a Machine Digimon whose name and design are derived from the steam locomotive. Its purpose in life is to keep running, and it is a being which transports the data within the Network across the Digital World. Within the Digital World, where a large quantity of information comes and goes, the meaning of life for Locomon and other Vehicle-species Digimon is in how quickly they can convey that information. However, there are times when old models of Locomon have run completely wild as a result of seeking to go too quickly. Also, although its range of movement is confined because it can only run on rails, there are occasions when it has generated spacial distortions by continuously running in circles.
