Final answer:
Hobos primarily used trains and hitchhiking as their forms of transportation, often riding in railroad boxcars and seeking lifts to travel in search of work.
Step-by-step explanation:
The two forms of transportation that hobos used were trains and hitchhiking. During the Depression, approximately 2 million men and 8,000 women found themselves wandering the country in search of employment. As hobos, they often hitched rides on railroad boxcars due to the lack of work within walking distance of their homes. Walking and seeking rides from others were common methods for traveling in hopes of finding work to support their families. Because of their transient nature and the practice of hopping onto freight trains, which was both dangerous and illegal, hobos have become a cultural symbol of the Great Depression era.
