Autonomous trains increasingly are seen as a solution to U.S. truck driver shortages, as well as a way for companies to reduce carbon emissions.
Florida A&M University's Maxim A. Dulebenets predicts that "trains are going to reach full autonomy faster than vehicles," especially since hundreds of passenger trains worldwide already operate autonomously as part of urban transportation systems.
However, most autonomous trains are built on newer, dedicated tracks that are not shared with human-controlled trains and generally do not include hazards like highway crossings.
Dulebenets said automating the U.S. rail network, in which multiple private rail companies share many lines, "could take decades."
There also are concerns about safety and cybersecurity.
