The anthropometric measures assessed included height, weight, body mass index (BMI), waist circumference, waist-hip ratio, waist-height ratio, trunk-cephalic height, conicity index, fat mass index (FMI) and fat-free mass index (FFMI).
The agreement includes at least the following track measurements, inspections and services - Track geometry, including the geometry of the measuring gear,- Measurement of the static contact line position,- Rail Contouring, wave measurement (wavelength of 30 to 1 000 mm)- Calculation of the effective conicity,- The bearing housing and the wagon body acceleration measurement,- Describing the view of the driver,- The measurement and reporting of inspection results.
Therefore, it is suggested that when a great distance between the initial path and its maximum projection (IC-MP) is observed radiographically, the anticurvature filing should be initiated with manual or rotary files of reduced conicity to increase the control of file orientation and filing in the danger zone.
