A rack railway is a steep grade railway with a toothed rack rail, usually between the running rails. The trains are fitted with one or more cog wheels or pinions that mesh with this rack rail. This allows the trains to operate on steep grades above 10%, which is the maximum for friction-based rail. Most rack railways are mountain railways, although a few are transit railways or tramways built to overcome a steep gradient in an urban environment.
Sudbury, officially the City of Greater Sudbury, is the largest city in Northern Ontario by population, with a population of 166,004 at the 2021 Canadian Census. By land area, it is the largest in Ontario and the fifth largest in Canada. It is administratively a single-tier municipality and thus is not part of any district, county, or regional municipality. The City of Greater Sudbury is separate from, but entirely surrounded by the Sudbury District. The city is also referred to as "Grand Sudbury" among Francophones.
Vale Canada Limited is a wholly owned subsidiary of the Brazilian mining company Vale. Vale's nickel mining and metals division is headquartered in Toronto, Ontario, Canada. It produces nickel, copper, cobalt, platinum, rhodium, ruthenium, iridium, gold, and silver. Prior to being purchased by CVRD in 2006, Inco was the world's second largest producer of nickel, and the third largest mining company outside South Africa and Russia of platinum group metals. It was also a charter member of the 30-stock Dow Jones Industrial Average formed on October 1, 1928.
Walden was a town in the Canadian province of Ontario, which existed from 1973 to 2000. Created as part of the Regional Municipality of Sudbury when regional government was introduced, the town was dissolved when the city of Greater Sudbury was incorporated on January 1, 2001. The name Walden continues to be informally used to designate the area.
The Sudbury Basin, also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, Canada. It is the third-largest known impact crater or astrobleme on Earth, as well as one of the oldest. The crater was formed 1.849 billion years ago in the Paleoproterozoic era.
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice. The section of rock that is being mined, known as the longwall panel, is typically 3–4 km (1.9–2.5 mi) long, but can be up to 7.5 km (4.7 mi) long and 250–400 m (820–1,310 ft) wide.
Vale S.A., formerly Companhia Vale do Rio Doce is a Brazilian multinational corporation engaged in metals and mining and one of the largest logistics operators in Brazil. Vale is the largest producer of iron ore and nickel in the world. It also produces manganese, ferroalloys, copper, bauxite, potash, kaolin, and cobalt, currently operating nine hydroelectricity plants, and a large network of railroads, ships, and ports used to transport its products.
Clayton Equipment Company Ltd, now known simply as Clayton Equipment Ltd or CEC and CEL, is a locomotive construction company that specialises in rail equipment, design and build, tunnelling, mining, metro, mainline and shunter locomotives.
The Sudbury and Copper Cliff Suburban Electric Railway was a privately-owned electric interurban railway and streetcar system that connected several neighbourhoods in the town of Sudbury, along with what was then the town of Copper Cliff in Ontario, Canada. Incorporated in 1912, the company began revenue passenger service in November 1915. It ultimately grew into a system of three radial lines which joined together in downtown Sudbury. By the late 1940s, however, rail service was being supplemented with diesel buses. Rail service ended in October 1950 and was completely replaced with bus service, which over time evolved into municipal Sudbury Transit and later GOVA services.
This is a list of neighbourhoods in the urban core of Greater Sudbury, Ontario. This list includes only those neighbourhoods that fall within the pre-2001 city limits of Sudbury — for communities within the former suburban municipalities, see the articles Capreol, Nickel Centre, Onaping Falls, Rayside-Balfour, Valley East and Walden.
Creighton Mine is an underground nickel, copper, and platinum-group elements (PGE) mine. It is presently owned and operated by Vale Limited in the city of Greater Sudbury, Ontario, Canada. Open pit mining began in 1901, and underground mining began in 1906. The mine is situated in the Sudbury Igneous Complex (SIC) in its South Range geologic unit. The mine is the source of many excavation-related seismic events, such as earthquakes and rock burst events. It is home to SNOLAB, and is currently the deepest nickel mine in Canada. Expansion projects to deepen the Creighton Mine are currently underway.
Frood-Stobie Mine is a nickel mine in Greater Sudbury, Ontario, named for Thomas Frood, an employee of the federal department of Crown lands who prospected and staked many of the early mining claims in the area. A major arterial road in the city is also named for Frood.
The Mond Nickel Company Limited was a United Kingdom-based mining company, formed on September 20, 1900, licensed in Canada to carry on business in the province of Ontario, from October 16, 1900. The firm was founded by Ludwig Mond (1839-1909) to process Canadian ore from mines near Sudbury, which were then shipped to Mond's works in Britain for final purification via his patented carbonyl process.
A minecart, mine cart, or mine car is a type of rolling stock found on a mine railway, used for moving ore and materials procured in the process of traditional mining. Minecarts are seldom used in modern operations, having largely been superseded in underground operations by more efficient belt conveyor systems that allow machines such as longwall shearers and continuous miners to operate at their full capacity, and above ground by large dumpers.
A mine railway, sometimes pit railway, is a railway constructed to carry materials and workers in and out of a mine. Materials transported typically include ore, coal and overburden. It is little remembered, but the mix of heavy and bulky materials which had to be hauled into and out of mines gave rise to the first several generations of railways, at first made of wooden rails, but eventually adding protective iron, steam locomotion by fixed engines and the earliest commercial steam locomotives, all in and around the works around mines.
The Vermilion River is a river in the Lake Huron drainage basin in Sudbury District and Greater Sudbury in Northeastern Ontario, Canada.
The Vale Railway, formerly the INCO Railway, is an industrial railway operating in the City of Greater Sudbury, Ontario, Canada. It is owned and operated by Vale Limited.
Modular Mining is a privately held company that develops, manufactures, markets, and services mining equipment management systems, headquartered in Tucson, Arizona, U.S.A.

The economy of Greater Sudbury, Ontario was dominated by the mining industry for much of the city's history. In recent decades, however, the city has diversified to establish itself as an emerging centre in a variety of industries, including finance, business, tourism, health care, education, government, film and television production, and science and technology research. Many of these industries reflect the city's position as a regional service centre for Northeastern Ontario.
The Coleman Mine is an underground nickel and copper mine operated by Vale 45 kilometres (28 mi) northwest of Sudbury, Ontario, Canada. It is the flagship mine of Vale's Sudbury operation. The mine recently implemented the use of electric haul vehicles and installed an underground 4G LTE network.
