Machine Design researchers have solved a serious train problem
Many train wagons equipped with a new type of brake blocks have had serious problems in winter traffic. There have been several media reports, for example including Sweden's television (SVT). Brake blocks made of composite material instead of cast iron work poorly even with no winter climate. Researchers at Machine Design looked closer at the issue last year and have already come across several solutions.
