The railway ascends the mountain beginning at an elevation of approximately 2700 feet (823 m) above sea level and ending at the summit of Mt. Washington at an elevation of 6288 feet (1,916.6 m). It is the second steepest rack railway in the world with an average grade of over 25% and a maximum grade of 37.41%. The railway is still in operation, using one or two steam locomotive

s and four biodiesel powered locomotives. 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), although the diesel can go up in as little as 37 minutes. It takes approximately 65 minutes to ascend and 40 minutes to descend. The railway is approximately 3 miles (4.8 km) long.

History

The railway was built by Sylvester Marsh (1803-1884) of Campton
Campton, New Hampshire
Campton is a town in Grafton County, New Hampshire, United States. The population was 3,333 at the 2010 census. Campton, which includes the villages of Blair, Campton Hollow, Lower Campton and West Campton, is home to Blair State Forest and Livermore Falls State Forest...

, who came up with the idea while climbing the mountain in 1857. His plan was treated as insane. Local tradition says the state legislature voted permission based on a consensus that harm resulting from operating it was no issue — since the design was attempting the impossible — but benefits were guaranteed: The $5,000 of his own money he put up, and whatever else he could raise, would be spent largely locally, including building the Fabyan House hotel at nearby Fabyan Station to accommodate the expected tourists. The railway is sometimes called "Railway to the Moon" because one state legislator remarked during the proceedings that Marsh should not only be given a charter up Mount Washington but also to the moon

Sylvester Marsh died in 1884 and control of the Cog passed to the Concord & Montreal Railroad, which ran it until 1889 when the Boston & Maine Railroad took over.

Control by the Teagues began in 1931 when Col. Henry N. Teague bought the Cog. In 1951 following Col. Teague's death, Arthur S. Teague, the colonel's protégé but no relation, became general manager. Arthur S. Teague gained ownership in 1961. After he died in 1967, the ownership passed to his wife, Ellen Crawford Teague, who ran the Cog as the world's first woman president of a railway. In 1983 Mrs. Teague sold the railway to a group of New Hampshire businessmen. The Cog has been in continuous operation since 1869 with service interruptions only during the World Wars.

In the summer of 2008, the Cog introduced its first diesel locomotive. The late 2000s recession

 and the 2000s energy crisis led to fewer passengers, and the Cog sought to cut costs with the diesel, which could make 3 round trips for the cost of one steam train round trip.

Devil's shingle

Since the early days of the railway's construction the workers wanted to minimize time when climbing and descending the ramp, so they invented slideboards fitting over the cog rack and providing enough room for themselves and their tools. These boards – no two were exactly alike – were approximately 90 cm (35.4 in) long by 25 cm (9.8 in) wide, made of wood with hand-forged iron and with two long hardwood handles usually attached at the down-mountain end. Common times for the descent of the mountain using these boards were about 15 minutes. The record was 2:45, an average speed above 100 km/h (62.1 mph).

The "Devil's shingles" were banned in 1906 after the accidental death of an employee. Later the design of the rack was changed so the old braking mechanism could not grip any more.

Accidents

The first of two major accidents in the railway's history occurred in 1929. The first locomotive

 broke and the locomotive began descending the mountain at high speed. All but one of its crew jumped to safety (though some suffered broken bones), but one man did not escape and died. Although the locomotive broke into pieces, the boiler did not rupture, and the pieces were later reassembled to reconstruct the locomotive for static display. It is now located at the Cog Railway Base Station.

On September 17, 1967, eight passengers were killed and seventy-two injured when Engine #3 derailed at the Skyline switch about a mile below the summit. The engine rolled off the trestle

 while the uncoupled passenger car slid several hundred feet into a large rock. An investigation revealed that the Skyline switch had not been properly configured for the descending train. The railway nonetheless has a solid safety record having taken almost five million people to the summit during its existence.

Mechanical design

Each train consists of a locomotive pushing a single passenger car up the mountain, and descending the mountain by going backwards. Both locomotive and car were originally equipped with a ratchet and pawl
Ratchet (device)
A ratchet is a device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction.

In 2004, work was completed replacing the lower Waumbek Switch and Siding with an 1800 feet (548.6 m) passing loop equipped with electric and hydraulicly powered automated switches. These switches are powered by batteries and recharged by solar panels. One switch is located at each end of the loop, allowing ascending and descending trains to pass one another.

Modern operations

The most common trips on the Cog Railway are between the two main stations, one at the summit and the other adjacent to the operators' logistical and repair base.

From 2003 to 2006, "ski trains" ran, stopping at an intermediate station, from which passengers could ski
