“Richard Carpenter is mapping every mile of America’s railroad system as of 1946. By hand. ‘It’s a story,’ he says, ‘that needs to be told.’ …What Dick Carpenter has engineered is A Railroad Atlas of the United States in 1946 , an encyclopedic work that is as audacious as it is artful. Carpenter aims to draw every mile of railroad track that existed in the United States in 1946. Volume one, published last summer, covers six mid-Atlantic states and more than 23,570 miles of active track. All of which raises a small question and a big one: Why 1946? And why at all?”
