In depth look at the DDA40X #6922 Worlds largest diesel locomotive

In the end I had several hundred scenes which took a long time to edit. But I think it turned out pretty good and it’s a rare look at nearly every aspect of the DDA40X. These locomotives were built by the Electro Motive Division of General motors from 1969-1971. There was 47 locomotives produced. Eleven locomotives have survived and are in museums.
