In Montreal, the dismantling of the Minirail, a suspended train originally built for the 1967 World's Fair, began three years after its last test run. The structure had stood as a metal skeleton in Jean-Drapeau Park since 2019, serving no practical purpose. The Minirail, which featured open gondolas rather than enclosed compartments, was once part of a network of three lines that connected the pavilions of the World's Fair. The yellow and blue lines were removed in the 1970s and 1980s, while the last line remained near the amusement park La Ronde. This section had continued to operate until 2019, but it was never restored after the pandemic. An inspection later found the structure unsafe, leading to its eventual removal. The Minirail's departure marked the end of a nearly six-decade legacy, and its dismantling came as a surprise to the city, with heritage groups expressing disappointment over the loss of a symbol tied to Montreal's identity. A similar story unfolded in Châteauneuf-sur-Loire, France, where in 1959, a test line was built to showcase a suspended metro using pneumatic technology. The project involved major French companies and attracted international interest, with delegations from countries such as the U.S., Germany, and Japan visiting to observe the innovation. Despite the initial enthusiasm, the project never moved beyond the test phase. A proposed line in Paris was ultimately replaced by a traditional metro line. Today, the test track is gone, but a restored cabin remains as a reminder of the project. Local media described the outcome as emblematic of a France that gave up on such ambitious projects, while Japan continued to pursue similar technologies. In Las Palmas, Spain, the story took a more abrupt turn. In 1971, a company proposed a suspended monorail connecting the city to Maspalomas via the airport, based on a system developed by engineer Alejandro Goicoechea, also known for the Talgo train. A prototype, called TV-2, was briefly tested along the Maritime Avenue but failed to gain support from the transport sector. The project was quickly abandoned and dismantled, with many of its components ending up in a ravine. The inventor later admitted in a televised interview that the project was doomed from the start, highlighting the challenges of getting such innovations off the ground. These three stories—Montreal, Châteauneuf-sur-Loire, and Las Palmas—share a common theme: short, experimental monorail lines that were built more as demonstrations than as practical transportation solutions. In contrast, the suspended monorail in Wuppertal, Germany, has been in continuous operation for over a century, carrying millions of passengers annually. The difference lies not in the engineering itself, but in the economic and practical considerations. While the German system became a vital part of daily life, the others were more about showcasing futuristic ideas rather than meeting real transportation needs.
