Mexico City Metro Overpass Collapse
On 3 May 2021, at 22:22 CDT ( UTC−5), an overpass in the borough of Tláhuac carrying Line 12 of the Mexico City Metro collapsed beneath a passing train. The overpass and the last two cars of the train fell onto Tláhuac Avenue near Olivos station, killing 26 people and injuring 98 others. It was the Metro's deadliest accident in almost fifty years. The line experienced technical and structural problems that led to a partial closure of the elevated section where the accident occurred between 2014 and 2015. An earthquake in 2017 further damaged the span; although it was repaired within a few months, residents reported problems still existed years later. The line was announced in 2007 as an underground line with the possibility of operating rubber-tired trains because of the instability of the city's soil. The line was scheduled to be opened by 2010 but due to the budget and time constraints, the project was modified to operate both underground and overground with ste ...

Excélsior
''Excélsior'' is a daily newspaper in Mexico City. It is the second oldest paper in the city after '' El Universal'', printing its first issue on March 18, 1917. History ''Excélsior'' was founded by Rafael Alducin and first published in Mexico City on March 18, 1917. In 1924, Alducin died at the age of 35, and his family led the newspaper into difficult times. Ultimately, it was reconstituted as a worker-owned cooperative in 1932, with one-time accountant Gilberto Figueroa named general manager. His ability to manage finances and broker compromise within the newspaper contributed to a successful 30-year reign, in which the newspaper would become politically and economically stable. Beginning in 1968, the newspaper's editorial stance was of a relatively liberal bent, under the editorship of Julio Scherer García. After Scherer left the newspaper in 1976, the editorial stance became more overtly supportive of the Institutional Revolutionary Party (PRI) and the Mexican establishm ...

In 2019, the station had a total average ridership of 85,800 passengers per day, making it the fifth busiest station in the network.

Metal Fatigue
In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size, which occurs when the stress intensity factor of the crack exceeds the fracture toughness of the material, producing rapid propagation and typically complete fracture of the structure. Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal ''crystallising'' because of the brittle appearance of the fracture surface, but this has since been disproved. Most materials, such as composites, plastics and ceramics, seem to experience some sort of fatigue-related failure. To aid in predicting ...
