The post-WWII Freedom Train carried the most important artifacts of American history to towns and cities across the country in an effort to tededicate citizens to the blessings of the American system. From 1947 to 1949, it received 3,521,841 visitors, who saw original documents such as the Declaration of Independence.
The American Locomotive Company furnished the train's motive power. This was the legendary PA-1, co-built with General Electric. It was a highly visible example of the capability od diesel power and probably hastened the demise of steam locomotives.
