Feasibility study
• SIMULATIONS IN MBS ACC. TO EN 14 363:
o Quasistatic safety against derailment
o Running safety
o Running behavior
o Suspension (sway) coefficient
• GAUGE CALCULATION

The dynamic behavior above the 3-axle bogie has been checked due to
position of secondary suspension

Conclusion
• The D-DART bogie provides the vehicles:
• Possibility to create articulated train with significantly longer sections
• Higher specific capacity of DD units
• Better performance of transport system
• Less vehicles in a fleet
• Lower own weight
• Lower train path charges
• Lower energy consumption
• Lower wheel-rail forces
• Lower wheel and rail wear
• Lower noise emission
• Lower train path charges
