All about the railroad: old coaches made new, ancient steam engines, historic hotels, stations and campsites along 64 miles of scenic track unlike any other railroad in the USA and the only one ever to penetrate to the heart of a national park. On 17 September 1989, 88 years to the day from the date the first steam engine puffed to the Grand Canyon, a reborn Grand Canyon train made its way from Williams to the Grand Canyon along the same historic route. The resurrection of the Grand Canyon Railway signifies more than steam and thunder, nostalgia and history. It is part of a growing recognition of the need to soften the environmental impact made by four million annual visitors to the Canyon. The railroad uses a clean burning fuel of oil and grey water for engine power and may reduce peak motor traffic in the Canyon park by as much as 4000 vehicles per day.
