RAIL SAFETYRegulators Blast Union Pacific for Running Unsafe Trains
The nation’s largest freight rail carrier failed to fix and continued to use faulty equipment, according to the Federal Railroad Administration. Managers reportedly pressured inspectors to leave the yard so they could keep freight moving.

ENERGY TRANSITIONRailroads May Use Their Monopoly Power to Buffer Coal Plants from a Carbon Emissions Tax
Railroads are likely to cut transportation prices to prop up coal-fired plants if U.S. climate policies further disadvantage coal in favor of less carbon-intensive energy sources. A new study argues that “If policymakers ignore real distortions in the market, like monopoly power in rail shipping, their climate policy efforts may not achieve the intended results.”

EVsPaving the Way for Electric Vehicle Adoption
For many car owners, their next purchase will be an EV. But as many current EV owners know, the environmental benefits of battery-powered cars come with a tradeoff and that tradeoff is the driving distance existing battery technology can support. The problem is the battery, specifically how much energy they can store, their longevity, and how long they take to charge.

CYBERSECURITYBolstering Cybersecurity in Navigation Systems
Interference such as jamming and spoofing that targets critical infrastructure has the potential to cause widespread delays and cascading failures across multiple modes of transportation including ships, trains, trucks, and cars—and the problem is only getting worse. New project aims to enhance resilience of transportation infrastructure against cyber threats, developing advanced countermeasures for GPS spoofing and jamming.

TRANSPORTATION SECUERITYTesting Environments Help Secure Transportation Infrastructure
“All critical infrastructure sectors—including the energy, manufacturing, and transportation sectors—rely heavily on sophisticated technologies like industrial control systems, cellular networks, and artificial intelligence,” said DHS S&T’s Alex Karr. “These are all accessed, monitored, and controlled via the internet, which, in turn, makes them susceptible to hacking, malware attacks, and other malicious activities.”

RAIL TRANSPORTATIONRailroad Unions and Their Employers at an Impasse: Freight-Halting Strikes Are Rare, and This Would Be the First in 3 Decades
The prospect of a potentially devastating rail workers strike is looming again. Strikes that obstruct transportation rarely occur in the United States, and the last one involving rail workers happened three decades ago. But when these workers do walk off the job, it can thrash the economy, inconveniencing millions of people and creating a large-scale crisis.

CLIMATE CHALLENGESWhy UK Railways Can’t Deal with Heatwaves – and What Might Help
Like most construction materials, steel, which rails are made from, expands when air temperature increases. When this movement is restrained by the anchorage, which holds the rail and the sleeper (the rectangular supports for the rails) in place, internal stresses build up, and compression buckles or kinks the rail. Trains cannot travel over rail lines with kinks. In the US, kinks caused by the sun caused over 2,100 train derailments in the past 40 years, equivalent to around 50 derailments per year.
