A pioneer in train photography, Steinheimer lived through and documented the railroad's heyday and its decline. He is one of very few photographers who appreciate the aesthetics of all locomotives, from steam engines to the latest diesel-powered behemoths. He has a particular fondness for the landscape of the American West, and many of his images situate trains in the larger geography and culture of the time. Known for taking pictures at night, in bad weather, and from risky perches on top of moving train platforms, Steinheimer has an enormous creativity and productivity.
