Traditionally, railways determine track superelevation based on the balanced speed of one axle and then reduce the resulting value by an arbitrary number called "unbalanced superelevation." This does not consider parameters such as multiple vehicle wheels, articulation of the train, train action, power location/distribution in the train, track curvature, grade, and thermal effects. Proper track/power asset management cannot be achieved without super-elevation policies that respect these parameters.

ARRT has developed and calibrated a track/train interaction software called Advanced Super-Elevation Toolkit (ASET) that considers all the parameters ignored by current standard practices. Ideal for scheduled railroads, ASET results are accurate and timely.

ASET MODULES

• ASET/SE computes the ideal superelevation for any traffic mix over any terrain
• ASET/SP optimizes speed profiles along any given route
• ASET/DP determines the distributed power needed to maintain desired speeds.

GENERAL FEATURES

• Handles and accumulates bi-directional traffic results
• Accommodates distributed power anywhere along each train
• Identifies problem areas
• Provides draw bar forces.
  

OVERALL BENEFITS

• Minimizes track forces
• Reduces damage to track asset and derailment probability
• Fuel savings and increased ROI.
