In my opinion, this is probably one of the finest pieces of industrial design ever built – the GG-1 Class electric locomotives of the Pennsy. As is often the case with ‘classics’ there’s been some debate about the precise designer of these fine locos as they are usually credited to the designer Raymond Loewy – however, now, it should be mentioned that the earlier works on this class were carried out by the equally famous Donald Roscoe Dohne. It was certainly Loewy who developed the final shape and livery – green until 1952 and then the classid Tuscan Red used by the Pennsy. The locos, 139 0f them in total, ran between 1934 and 1983. They were built by General Electric and the Railroad’s Altoona Locomotive Works.
