context_page_description: The Mount Washington Cog Railway, also known as the Cog, is the world's first mountain-climbing cog railway. The railway is still in operation, climbing Mount Washington in New Hampshire, United States. It uses a Marsh rack system and both steam and biodiesel-powered locomotives to carry tourists to the top of the mountain. Its track is built to a 4 ft 8 in gauge, which is technically a narrow gauge, as it is ¹⁄₂ inch less than a 4 ft 8 ¹⁄₂ in standard gauge.
  It is the second steepest rack railway in the world after the Pilatus Railway in Switzerland, with an average grade of over 25% and a maximum grade of 37%. The railway is approximately 3 miles long and ascends Mount Washington's western slope, beginning at an elevation of approximately 2,700 feet above sea level and ending just short of the mountain's summit peak of 6,288 feet. The train ascends the mountain at 2.8 miles per hour and descends at 4.6 mph. Steam locomotives take approximately 65 minutes to ascend and 40 minutes to descend, while the biodiesel engines can go up in as little as 36 minutes.

The railway is still in operation, climbing Mount Washington in New Hampshire, United States. It uses a Marsh rack system and both steam and biodiesel-powered locomotives to carry tourists to the top of the mountain. Its track is built to a 4 ft 8 in (1,422 mm) gauge, which is technically a narrow gauge, as it is ¹⁄₂ inch (1.3 cm) less than a 4 ft 8 ¹⁄₂ in (1,435 mm) standard gauge.
  It is the second steepest rack railway in the world after the Pilatus Railway in Switzerland, with an average grade of over 25% and a maximum grade of 37%. The railway is approximately 3 miles (5 km) long and ascends Mount Washington's western slope, beginning at an elevation of approximately 2,700 feet (820 m) above sea level and ending just short of the mountain's summit peak of 6,288 feet (1,917 m). The train ascends the mountain at 2.8 miles per hour (4.5 km/h) and descends at 4.6 mph (7.4 km/h). Steam locomotives take approximately 65 minutes to ascend and 40 minutes to descend, while the biodiesel engines can go up in as little as 36 minutes.
  Most of the Mount Washington Cog Railway is in Thompson and Meserve's Purchase, with the part of the railway nearest to Mount Washington's summit being in Sargent's Purchase.
