Atomic Age / First Generation F-Unit Diesel Locomotive Era (Poster in progress)

This is a poster I am working on which represents the completion of the next phase on the Northwest Trunk Lines Model Railroad. Each Poster in a progressive series is themed to be more contemporary than the previous. This poster is the dawning of an atomic age for American and the introduction of the diesel locomotive, replacing the steam engines. This is only a second draft and I think the text is a bit too tattered to read. I am working on the railroads logo so that it fits the early 1960's design.
