Axle Load Speed Load km/h mph tonnes km/h mph tonnes TGV SUD-EST (mail TGV) 2 (mail and postal) motor car 1. wagons TGV Atlantique Not Allowed Not Allowed TGV Nord Europe Not Allowed Not Allowed ICE Germany (Power 19.4car) 16 km/h (Parcel Intercity) 16.3 (Coach) 1 km/h AVE Spain (Loco.) Not Allowed Not Allowed Shinkansen Not Allowed Not Allowed Shinkansen Tokaido New Construction Amtrak NEC (Power 25.5car) Not Allowed Not Allowed 15.9 (Coach) (Loco.) (Wagon)

5 Vehicle/Track Interaction Measuring System Goals Measure the Train/Track Forces to Determine the Induced Stresses Cause by each Train Service Provider Assess safety conditions in near real time by identifying Bad Acting vehicles Develop proactive track and vehicle maintenance intervention plans based on vehicle performance deterioration trends Determine utilization of the infrastructure by service provider incorporating the train routes and the condition of the fleet Engineering

6 Planned System Implementation Installation of approximately 15 wayside and gate- keeping site installations within 5 years to include one or more of the following: Weigh-in in-motion measurements. Wheel Impact Detection measurements. Vehicle Dimension measurements. Skew axle or skew truck detection measurements. Wheel profile measurements. Hot Box detection measurements. Dragging Equipment Detectors. gate-keeping Development of tools and applications that work with wayside data
