Cruise Control
10.1 General
With Cruise Control the train driver sets a speed, that is then reached and maintained by the train.
To equip an electric or diesel locomotive with CC, following steps must be performed:
1) In the .eng file the required entries must be provided
2) in the .cvf file the required cab controls must be added
3) in the .sms files the required sound stream entries must be added.
To drive a locomotive that has been equipped with CC following driver interfaces are available:
1) Keyboard commands
2) Mouse
3) HUD and Train Driving window.
The CC feature includes also the management of a very versatile specific controller, called Multi Position Controller (MPC).
A paragraph is devoted to each of the above topics.
10.2 Operation Modes
The CC Speed Regulator can be in 4 different states (or modes), that is:
1) Manual, when the automatic cruise control is disabled and the driver controls the speed through throttle and brakes as if there were no CC.
2) Auto, when the automatic cruise control is enabled, and therefore the speed is automatically controlled
3) Testing, not implemented at the moment
4) AVV, not implemented at the moment.
Switching betweenManual and Auto mode can be configured to occur either by a specific cabviewcontrol (ORTS_SELECTED_SPEED_REGULATOR_MODE) or when certain conditions, defined in the .eng file parameters, are met, or by keyboard commands. One of such parameters is e.g. ForceRegulatorAutoWhenNonZeroSpeedSelected.
The CC Speed Selector can be in 4 different states (or modes), that is:
1) Parking
2) Neutral
3) On
4) Start.
Switching betwenn Speed SelectorModes can be configured to occur either by a specific cabview control (ORTS_SELECTED_SPEED_MODE) or through keyboard commands.
The Cruise Controller can be of three types:
1) None
2) Full
3) SpeedOnly
The type selection occurs through .eng parameter ControllerCruiseControlLogic. Types None and Full work the same way. None is default, meaning the full Cruise Controller features are active.
10.3 Parametrizing the .eng file
In the Engine section of the .eng file the CC parameters must be declared within an ORTSCruiseControl block, this way:
ORTSCruiseControl(
CCparameter1 (value)
CCparameter2 (value)
...
CCparametern (value)
Options ("Option1", "Option2", ... "Optionn")
ForceStepsThrottleTable ("IntValue1", "IntValue2",...,"IntValuen")
AccelerationTable ("FloatValue1", "FloatValue2",...,"FloatValuen")
)
A list of the available .eng file CC parameters follows here below.

The presence of ForceStepsThrottleTable and AccelerationTable is optional.
Braking by CC can occur either using only the dynamic brake (default) or using only the train brake, when the locomotive has no dynamic brake, or using both the dynamic brake and the train brake. For this to occur parameter UseTrainBrakeAndDynBrake must be set to true in the CruiseControl block within the .eng file.
Train brake usage occurs when the delta between the actual train speed and the target speed is higher than parameter SpeedDeltaToEnableTrainBrake. Between this delta and SpeedDeltaToEnableFullTrain- Brake the train brake is set at TrainBrakeMinPercentValue. Above SpeedDeltaToEnableFullTrainBrake the train brake is continuously adjusted to achieve a constant deceleration. In other words, when the speed delta is high, train braking is adjusted to obtain a constant deceleration when dynamic braking is not enough; when train decelerates and delta reduces to SpeedDeltaToEnableFullTrainBrake the train brake is reduced to TrainBrakeMinPercentValue. When train decelerates further and delta reduces to Speed-DeltaToEnableTrainBrake the train brake is released. By adjusting these parameters to the locomotive and a typical train it pulls, it can be made sure that the brake pipe is fully recharged when the target speed is reached. Else the train speed could be significantly reduced below the target speed.
An example of the relevant lines in the CruiseControl block within the .eng file follows here:
UseTrainBrakeAndDynBrake ( True ) comment (** CC uses train brake and dyn brake together␣˓→**)
SpeedDeltaToEnableTrainBrake ( 15km/h ) comment (** This is the minimum speed␣˓→delta between actual speed and desired speed for the CC to use also the train brake **)
SpeedDeltaToEnableFullTrainBrake ( 30km/h ) comment (** This is the minimum speed␣˓→delta between actual speed and desired speed for the CC to use also the train brake␣
˓→with no reduced intensity **)
TrainBrakeMinPercentValue ( 10 ) comment (** This is the minimum train brake␣˓→percent used by the CC, where 0 means no braking and 100 full braking **)
TrainBrakeMaxPercentValue ( 60 ) comment (** As above for maximum value. It must␣˓→not be too high to avoid that the brake is not fully released timely **)
10.3.1 Multi Position Controller (MPC)
It is possible to manage a CC also without a MPC, in case the throttle controller is used for CC, or a proportional speed selector is available. In the other cases in general a MPC is needed.
The Multi Position Controller(s) (more than one can be defined) is defined in the .eng file too with an ORTSMultiPositionController block, this way:
ORTSMultiPositionController (
Positions (
Position ( PositionType1 PositionFlag1 "PositionName1" )
Position ( PositionType2 PositionFlag2 "PositionName2" )
...
Position ( PositionTypen PositionFlagn "PositionNamen" )
)
ControllerID ( ID )
ControllerBinding ( "Controller Linked" )
CanControlTrainBrake ( Boolean )
)
The list of the available PositionTypes may be found in the table here below.
Table 3: MPC Position Types
| Position type | Description |

10.4.1 Restricted Speed Zone
Strictly this is not a Cruise Control function. When the driver sets the cabview control ORTS_RESTRICTED_SPEED_ZONE_ACTIVE, the Cruise Control sets to true and displays a boolean variable. This boolean variable remains true until the full length of the train has passed the point where the driver set the cabview control. When the variable returns false, also a sound trigger is activated.
This feature helps the train driver to identify when the full length of the train has passed a restricted speed zone, so that he can again increase speed of the train.

10.9 Sample files of a CC equipped electric locomotive
The E464 is the Italian electric locomotive that has been built in the highest number of exemplars.
Here below is a picture of the E464 cabview:
Following relevant items are circled in the picture:
1) Manual throttle-dynamic brake combined control lever (CP_HANDLE COMBINED_CONTROL in cvf file)
2) CC maximum acceleration lever (ORTS_SELECTED_SPEED_MAXIMUM_ACCELERATION LEVER in cvf file)
3) Multi position controller lever used to set the target speed (ORTS_MULTI_POSITION_CONTROLLER TWO_STATE in cvf file); it has four positions: unstable target speed increase position, stable neutral position, unstable target speed decrease position, and unstable target speed to zero position
4) Target speed digital display (ORTS_SELECTED_SPEED DIGITAL in cvf file)
Switching from manual to auto mode and vice-versa occurs only when levers 1 and 2 are in the zero position and lever 3 is in the neutral position. If at that point lever 1 is moved, CC switches to (or remains in) manual mode. If at that point lever 2 is moved, CC switches to (or remains in) auto mode.
The cvf file for the E464 equipped with CC (and also with customized TCS) can be found in the Open Rails folder in DocumentationSampleFilesManuale464_V2SCMT_SCMTscript_alias_CC.zip.
The eng file for the E464 can be found in the Open Rails folder in DocumentationSampleFilesManualFs-E464-390.zip.
10.10 Sample files of a CC equipped locomotive with proportional speed selector
The E652 is one of the first Italian electric locomotives which was equipped with power electronics. Differently from the E464, the preset speed is not set by a multiposition controller, but by a proportional lever, situated at the right of the cabview. “Proportional” means that at every position of the lever a different preset speed corresponds. Zero speed is set when the lever is at the “lowest” position, and the maximum speed is set when the lever is at the “highest” position. The lever is named “ORTS_SELECTED_SPEED_SELECTOR” in the cvf file.
The cvf file for the E652 equipped with CC (and also with customized TCS) can be found in in the Open Rails folder in DocumentationSampleFilesManual652_CC.zip.
The eng file for the E652 can be found in the Open Rails folder in DocumentationSampleFilesManual652_CC.zip.
