Since the 19th century, trains contributed to an economic and social boom in Europe and the world. This significant impact has continued to this day. Clear signs, however, came to question their contribution to the climate change.

Transportation, particularly trains, are of special importance for the economies of the world, their advancement, and social stability. They are a pivotal link in the supply chains of goods, in addition to being the nearly sole means of travel for social classes that cannot afford the cost of flying over long distances."

But how can the hear negatively affect trains?

But Costa Samaras, Principal Assistant Director for Energy and OSTP Chief Advisor for the Clean Energy Transition, White House Office of Science and Technology Policy, stated that most of the infrastructure built in the past relied on temperature records from the mid-20th century, which is no longer the climate we live in now. This is particularly true for railways, which depend on steel tracks that can be severely affected by high temperatures.

Lad Keith, associate professor of planning and head of sustainable built environments at the University of Arizona's College of Architecture, Planning, and Landscape Architecture, explained to the Washington Post that asphalt and concrete roads, airport runways, and railways are among the most exposed infrastructures to the risks posed by rising temperatures.

"Tracks at Risk" Jo Seias, a professor of civil and environmental engineering at the University of New Hampshire, said that extreme heat will cause the steel tracks of the railways to expand, leading to bending that endangers trains.

Studies indicate that the bending of railway tracks will gradually result in train delays, forcing them to operate at lower speeds, which will extend travel times for individuals and push back deadlines for transporting goods and products. Increases in travel times will also lead to higher fuel costs for consumers, resulting in increased product prices and train travel costs. "Recent Incidents" Today, the railway authority in Moldova reported that 6 grain cars in a 61-car train heading to a river port in Ukraine derailed in Moldova yesterday after extreme temperatures weakened the tracks. The Moldovan railway stated in a report, "The initial cause of the incident is the extremely high temperatures that caused the tracks to lose their strength."
