resistance

Type: Decimal
Desc: Not used

adhesion

Type: Decimal
Desc: Not used

maxvoltage

Type: Decimal
Desc: Voltage to traction motors. This is used to scale the ammeter displayed in the cab. (Power is volts times amps - increasing the voltage means reducing the ammeter...)

maxspeed

Type: Decimal
Desc: Maximum speed in DCC mode.

brakeratio

Type: Decimal
Desc:

max-accel

Type: Decimal
Desc: Accelerative force available in DCC mode. Note - this is a force, not a rate of acceleration. The rate of acceleration will depend on the mass of the train as well.

max-decel

Type: Decimal
Desc: Decelerative force available in DCC mode. Note - this is a force, not a rate of deceleration. The rate of deceleration will depend on the mass of the train as well.

throttle-notches

Type: Integer
Desc: Number of throttle notches

axle-count

Type: Integer
Desc: Number of axles on this vehicle. Used in rolling resistance calculations.

surface-area

Type: Decimal
Desc: frontal surface area (sq ft) of vehicle. Used in air resistance calculations.

moving-friction-coefficient

Type: Decimal
Desc: Used in rolling resistance calculations.

air-drag-coefficient

Type: Decimal
Desc: Used in air resistance calculations.

full-throttle-speed

Type: Decimal
Desc:

driving-wheel-weight-ratio

Type: Decimal
Desc: Ratio (between 0.0 and 1.0) of the weight of this vehicle bearing down on driven wheels. Used by steam locos only.
