Mount Hood Railroad, Heritage railway in Hood River County, United States.

The Mount Hood Railroad runs about 22 miles (35 km) from Hood River south to Parkdale, climbing through a switchback and passing the communities of Pine Grove, Odell and Dee. Its trains cross orchards and farmland with views of Mount Hood and Mount Adams. The line was listed as the Mount Hood Railroad Linear Historic District on the National Register of Historic Places in 1994.

The line south from Hood River was built in 1906 as far as Dee, and in 1909 it was extended to Parkdale, the present end of track. Union Pacific acquired it in 1968, serving fruit shippers and the lumber operation at Dee. In 1987 local investors bought the railroad from Union Pacific and began passenger excursions.

The railroad's excursion trains run through the Hood River Valley's orchards and farmland, and the line's freight history is tied to fruit shippers and the lumber operation at Dee. Passengers can see working orchards from the train, and the railroad now promotes agritourism in the valley.

The line runs about 22 miles from Hood River to Parkdale, with a switchback near the start where the train reverses direction. The excursion lasts around four hours with a guide aboard. Open cars expose riders to wind, so bring warm layers; the dinner train uses enclosed dining cars.

The route features one of only a handful of remaining railroad switchbacks in the country, engineered to tackle a steep grade in the lower canyon. This construction method allowed early trains to climb slopes that would otherwise be impossible.
