Although the Blackford County Historical Society lists this community as a ghost town, homes are still maintained in the area.

During the next few decades, the quality of automobiles and roads improved—indirectly contributing to the decline of many small communities as consumers drove to larger cities.

[10] When Blackford County's railroads were constructed in the late 1860s, Trenton was bypassed—as the nearest rail line was four miles south of the small town.

Improvements to the automobile and highways, which coincided with the end of the Gas Boom, may have also contributed to the decline of the county's smaller communities as consumers became willing to travel to larger cities.

[12] Located in the Jackson Township portion of Blackford County, Trenton is situated on Indiana State Road 26.

Future Northern Indiana, including what became Jackson Township and Trenton, was flattened by two glaciers millions of years ago.

[14] These glaciers are also responsible for the rich Blackford County farmland, which includes the land surrounding Trenton.
