Fraunhofer Institute for Nondestructive Testing IZFP The business unit "railway" is characterized by the world-wide upgrading of the highspeed network at concurrently ingreased maintenance standards. Thus, major activities of the business unit concern the development and marketing of automated inspection and monitoring systems for wheel set components in the frame of the light and heavy maintenance of railway operators.
