Curve Resistance in Transportation System Formulas

Curve resistance is the added resistance or “drag” on a train that must be overcome by the tractive effort in rounding a curve. Resistance is usually measured in newtons per ton of train weight. And is denoted by CR. Curve Resistance is usually measured using the 1 per Mile for Reciprocal Length. Note that the value of Curve Resistance is always positive.

FAQ

What is the Curve Resistance?

Curve resistance is the added resistance or “drag” on a train that must be overcome by the tractive effort in rounding a curve. Resistance is usually measured in newtons per ton of train weight. Curve Resistance is usually measured using the 1 per Mile for Reciprocal Length. Note that the value of Curve Resistance is always positive.

Can the Curve Resistance be negative?

No, the Curve Resistance, measured in Reciprocal Length cannot be negative.

What unit is used to measure Curve Resistance?

Curve Resistance is usually measured using the 1 per Mile[mi⁻¹] for Reciprocal Length. 1 per Meter[mi⁻¹], 1 per Kilometer[mi⁻¹], 1 per Yard[mi⁻¹] are the few other units in which Curve Resistance can be measured.
