Supported Tags
The Motor container supports the following tags. Each tag is show here with its default value.

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: Coefficient between the pressure in brake cylinder and the brake force.
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
- Description: Specifies the number of throttle notches in the cabin. By default, all (non-steam) locos have 8 throttle notches, but this may be overridden with this tag. Note that this has no impact on train power output, unless the engine also enables the throttle-power-extended-notch-range or dynamic-brake-extended-notch-range options, and provides the relevant data in the power output graphs.
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: Obsolete- no longer used. (Previously: maximum speed with DCC throttle at 100%)
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.
Resistance calculations
These calculations occur according to Davis formula:
R = (1.3·m + 29·axle-count) + moving-friction-coefficient·m·V + air-drag-coefficient·surface-area·V^2 + 20·m·G
R = total resistance in lb. including grade resistance
V = speed - mph
m = weight of the vehicle (tons)
G = % grade (upgrade +, downgrade -)
