In the ETR400, and in general in the Italian locomotives, there is no equivalent of the Shift+W command. To pass from auto to manual you must have the combined handle in the central position and the selected speed at zero. Therefore when you pass back from manual to auto (which again requires that the combined handle is in the central position) the selected speed is at zero. So using Shift+W to change mode is not prototypical neither for the ETR400; the same applies also for the E464, that has separate force regulator and throttle levers. Therefore it doesn't occur that the MPC starts with a value with decimals.

So using the Ctrl+W for such locomotives is like using the brake reset command: something that hasn't its counterpart in the real world.

I see, then it makes sense to keep SpeedSelectorIsDiscrete ( 1 ) by default. I reverted the previous fix that only set that if there is no MPC (which was less elegant). Thanks!

[Csantucci]

César, thanks for what you are doing and for the fruitful exchange of info.

[Csantucci]

I have now tested and everything seems to be OK. Thanks!

Hello everyone
Could you please add an ENG ORT cruise control here?
Nothing's working for me again.
Unfortunately, I'm not an IT expert.
Thanks

[cesarbl]

Can you post the .eng that is not working for you?

Getting back to experimenting this feature as I have gotten the interest from being on the real thing dealing with both Slow Speed Control, Power % Reduction (GEVOs have ReoState like feature derating total consists power %) and Trip/Fuel Optimizers. With Slow Speed control I love how GE C44 an ES44 controls it by far better smoother than SD70ACe. 70ACe at target speed will exceed intended throttle force just to get to target speed quick even while trying to slow down with some air set. On C44AC and C45AC I been switching with, I like how speed control goes by the set throttle force not exceeding anything which makes it easier to yard and switch though the max you can set is 10MPH and traction gradually reduces regardless of which notch is set as it pays attention to the accelerometer on flat or ascending grade.

I'm looking for a few features that either fit into cruise/speed/power control or other subjects:

1. For the future of either PTC or/and Trip optimizer cruise controls would it be possible to code a Cruise Control parameter to obey speed limits as well as have a delta parameter to react to upcoming speed changes set by the distance (React to slow down by the set value distance like mile or feet)? Though PTC is ways away from ORTS in real life it does not trust trip optimizer automated controls to continue past an approach signal or in under a mile an half to a stop or restricting indication and uses its own method to warn the distance for upcoming changes as well has a penalty braking distance calculating total brake force available to stop behind the speed post or signal speed change at danger if it detects exceeding by a margin of 4MPH or emergency braking from passing stop signal at danger by 300-74 feet (better be stretch braking to reduce projected distance exceeding accelerometer).

This reacting to speed limit changes ahead not only will be helpful for simulating Trip/Fuel Optimizing but it gets rid of the faulty glitchy AI Auto Control while in the cab. AI Auto control doesn't even fallow max acceleration or target speed but does 2 futures that should also fit into parameters under Cruise Control... look at 2.


2. Is it possible to get a parameter placed in Cruise Control to have the option to turn off the Alerter while in the cab as well as have the Automatic bell to move and Horn sequence at crossings?


3a. I have successfully got to getting my test units to allow stretch braking (Power Run 1-5 with Air braking set) and power braking (Power Run 6-8 with Air Braking set) but is there a way to get the max acceleration set to 0 Idle to fully apply independent brakes as an engineer's worse nightmare in these modern days of RCL operations in speed target notches for power and separate brake reduction notches?

3b. I got to yet test a heavier train for when dynamic is not sufficient to slow the train down in time but what parameter out there gets cruise control to prompt or automatically set air if any? Either it prompts engineer how much air to set between Minimum reduction in PSI not exceeding 10 deduction on real thing or it gradually sets on its own we know it needs to stop at target speed of 0 or behind a signal displaying 0MPH between 400-74 Feet.


4. Though ReoState like future may be out of this subject it does govern how much power throttle output is maxed at Run 8 that you can get a leading C45AC, C44ACM to derate the whole power consists down to low horsepower switcher each (Each Throttle Notch is derated by that percentage via power and traction curve).




Combination of these and existing parameters makes it possible to making a conductor like mode feature despite the lack of parameters by using cruise control planning either station stops, or other stops intended on their own by changing target speeds under the speed limit but its not really their job to set air, sound all crossings but they can tell engineer what max throttle acceleration to use as well as what speed to go lol. Thanks for all the existing and tweaked parameters to getting this cruise control feature in great shape as its been helpful testing multiple optimizing trips, parameters and fuel conservation practices.

1. This is an advanced feature that can be achieved with a custom Train Control System (TCS) script. Given the wide variety of TCS and their complexity, it's not possible to include all of them in OR. Nevertheless, many TCS scripts have been developed by different people. The automatic speed control feature, which instructs Cruise Control to obey speed limits and stops, is quite recent, and it's only implemented by the LZB script (german cab signalling system).

2. This is also a cab signalling feature, and is part of the TCS subsystem, not cruise control. It can be done, but requires C# programing knowledge to develop the script.

3a. I don't understand the question, sorry.

3b. Cruise control can automatically apply air brakes if dynamic brakes are not enough, by setting the UseTrainBrakeAndDynBrake ( 1 ) parameter.

4. We are slowly working on custom traction motor controllers, but nothing is available yet.

Sounds like TCS scripting is the way and AI Control till a good TCS script is made or used from scratch. AI auto control just needs to obey targets.

Tried UseTrainBrakeAndDynBrake ( True ) it works at controlling high speeds but as dynamics fade to weaken or setting target speed to 0 to stop it doesn't use train airbrake and train rolls freely.

Don't really mind or pay attention to 3a as its just what useless remote controller switching units do in North America freight.

As for 4. it is just a dial or button with a percentage reduction while other options is to turn certain traction axles off or a whole bogie traction set off.

For CC to operate at low speeds with train brake you may need SpeedDeltaToEnableTrainBrake ( 0 )

Note that train braking only works as expected in Unstable and NewYear releases.

[amaljith]

but adding cruise control will make the driving will be easy and not that much fun on that
