Built specifically for the Pennsylvania Railroad, the GG1 was a unique, streamlined electric locomotive. They were also long lived-the GG1 was introduced in 1935, and served with the Pennsy, as well as successor companies Penn Central, Conrail, and Amtrak. The last GG1 left service in 1983.
Of the 140 GG1's built, fifteen survive. Sadly, none are currently operational, due mostly to the expense and other difficulties related to the large electrical transformers needed for such a large electric locomotive. This one, PRR 4927, served with Amtrak until the late 70's, and is now in storage at the Illinois Railway Museum.
