Amy Jewel at Triplepundit has penned a fantastic, brief history illustrating the role that railroads had in securing the establishment of the National Park Service. While she rightly pointed out that Amtrak remains a key (and environmentally friendly) link to many National Parks, Amtrak and the NPS continue to promote awareness of the importance of National Parks and their connection to railroads through the Trails & Rails narrative guide program.
