Montreal Metro

The Montreal Metro is a rubber-tired underground rapid transit system located in Quebec, Canada.

It serves as a vital transportation network for the Greater Montreal area. This system is essential for moving large numbers of people through the city efficiently. Currently, it stands as Canada's second busiest rapid transit system. In North America, it is the fourth busiest system, following the New York City Subway, the Mexico City Metro, and the Toronto subway.

The network provides connections across the north, east, and center of the Island of Montreal. It also links to Longueuil via the Yellow Line and to Laval via the Orange Line.

A unique feature of the Montreal Metro is its use of rubber tires instead of traditional steel wheels.

This design choice was inspired by the Paris Métro in France. Using rubber tires provides two main technical advantages for the trains. First, it allows the trains to accelerate much faster than steel-wheeled systems. Second, it enables the trains to climb steeper grades, or slopes, while traveling underground. To accommodate this system, engineers built 80% of the tunnels by carving through solid rock. This differs from the "cut-and-cover" method used for the Yonge Subway in Toronto.

The history of transit in Montreal began as early as 1861 with horse-drawn cars.

As the city grew, streetcar lines were added to provide service throughout most of the city. However, urban congestion eventually made it difficult for streetcars to remain punctual. For fifty years, many groups proposed different subway projects that never came to fruition. Some attempts were stopped by World War I and the Great Depression. Others failed because city officials were reluctant to provide necessary funding. A proposal in 1939 by Mayor Camillien Houde aimed to provide work for the jobless. Eventually, the re-election of Mayor Jean Drapeau and the work of Lucien Saulnier made the Metro a reality.

Construction of the initial network officially began on May 23, 1962.

The project was supervised by the Director of Public Works, Lucien L'Allier. At its peak, the construction project employed more than 5,000 workers. Tragically, the construction process resulted in the deaths of 12 workers. The system was inaugurated on October 14, 1966. When it first opened, the Metro consisted of only 22 stations spread across two lines. These original lines were the Green Line, also known as Line 1, and the Orange Line, or Line 2. The Green Line runs between Atwater and Honoré-Beaugrand stations. The Orange Line runs from Crémazie to Côte-Vertu.

The network expanded significantly to prepare for the 1967 Universal Exposition, known as Expo 67.

The city decided to prioritize the Yellow Line, or Line 4, to link Montreal to the South Shore. This line passes under the Saint Lawrence River to reach Longueuil. The construction of this line even helped shape the local geography. Engineers used excavation material from the Metro tunnels to enlarge Saint Helen's Island. They also used this material to create Notre Dame Island from scratch. The Yellow Line was completed on April 1, 1967, just in time for the World's Fair. This expansion helped the total construction and equipment cost reach $213.7 million.

Another major period of growth occurred around the 1976 Summer Olympics.

In 1971, a loan of $430 million was approved to fund various extensions. This included expanding the Green and Orange lines and building the Blue Line, or Line 5. The Green Line was extended toward the east to reach the Olympic Stadium site. Later, it was extended southwest to serve the suburbs of Verdun and LaSalle. However, soaring costs led the Government of Quebec to declare a moratorium on expansion in 1976. This pause froze many projects, including parts of the Orange and Blue lines. Eventually, the moratorium was partially lifted in 1977, allowing for further growth.

Today, the Montreal Metro has grown from its small beginnings to a massive 68-station network.

It is managed by the Société de transport de Montréal, or STM. The system's evolution shows how urban needs change over decades. What started as a dream for a city struggling with streetcar congestion is now a cornerstone of Quebec's infrastructure. The Metro connects diverse neighborhoods and suburbs to the heart of the city. It remains a primary example of how specialized engineering, like rubber-tired technology, can solve urban transport challenges.
