Doodlebugs were popular in the early 20th century for short-distance rail travel between towns.
In rural areas, doodlebugs provided essential transportation, connecting communities to larger cities.
By the mid-20th century, doodlebugs gradually fell out of favor as larger, more versatile trains became commonplace.
Despite their declining use, some preserved doodlebugs can still be seen in railway museums across the country.
The doodlebug's design made it efficient for routes where full-size trains were impractical.
