Next Generation Train (NGT HGV) Topics and Goals
• Increasing the certified train speed to 400 km/h• Halving the specific energy consumption double deck high speed train
• Noise reduction• Increase of comfort• Improvement of the driving safety• Improvement of wear behaviour and life cycle costs• Cost-efficient design: through modularization and
system integration• Increasing efficiency of development and
permission processes

•
Reduction of energy▫
Standardized service profiles for Highspeed, Intercity, Regional and Suburban passenger transport
▫
Travel times and dwell times in stations defined in timetable
▫
Free choice of velocity profile as long as timetable is kept
Motivation light weight design for trains
Suburban Regional Intercity High- Speed
Total distance km 40 70 250 300
Number of stations 12 15 10 3
Maximum speed km/h 120 140 200 300
Min. station distance km 2 2 15 90
Max. station distance km 7 10 60 210
Mileage km/year 100000 130000 275000 550000

Reduction of energy
•
Less energy consumption for acceleration and breaking
Motors and brake equipment lighter and smaller realisable
Less unsuspended weight
Reduction of cost of operation
Motivation light weight design for trains
