1st: Is it possible to implement the acceleration percentage control in a two state ON/OFF control so that when pressing it the acceleration is 100% and when pressing it again it is 0%?

Yes, just use the following:

MaxForceSteps ( 1 )

Hello jtr1962!

Yes, it works and it helps me to understand more how it works. Thanks!

Unfortunately I can't turn the power off and on from the same switch. I will try with a three position one, let's see...

Well, it doesn't work either.

Antuan, i have created the "prefijada" and the functional "ato-atf" for many trains, including the civia, is published.

With the full help of Csantucci, he has everything working except the reduced voltage.

If you want to know more you just have to comment me on messenger or through this forum :)

In these videos you can see the two systems in operation

Thanks for the videos, Alberto. Very interesting. Hopefully I can get to implement all this, for now I have a lot of work....

You can include mine already made for the trains you need, inside the files there is a .txt with different configurations for trains, look for the one from civia and you can use it for future updates

Thank you Alberto & Co., I am already implementing it. Some changes will have to be made to show the word "AUTO" in the panel, where now it says "MANUAL".

There is so much to do...

Now I need a lesson in how to do this. I want to try British slow speed control.

This has a switch in the cab with 4 positions

1 - 0.5 mph

2 - 1.0 mph

3 - 2.7 mph

[4 - "balancing speed" with diesel engine idling - depends on train load and gradient - usually about 7 or 8 mph - when the train reaches this speed the throttle can be closed and the slow speed control turned off. (Throttle must be closed before slow speed control can be disengaged.)]

or 4 - OFF - normal throttle control

Is there a way I can approximate this behaviour in an eng file for MG?

I am assuming if it works in MG now, that the other version will ignore it until such time as it is also working in that version too.

Hi Darwin,
this would probably require some additions to the existing code. I don't know what effort that could require.
Some questions:
1) is this used in diesel locos, in electric locos or both?
2) what does the speed control use? Only regulation of the tractive force, or does it use also dynamic braking and air braking if needed?
3) I'm not sure I understood the "balancing speed" way of working. If throttle is closed and slow speed control is disengaged, how can the train keep a speed? Is position OFF present also in case there is a "balancing speed" position?

[darwins]

Thanks Carlo,

1) In UK this is only used in diesel electric locos. I believe other countries in Europe may have slow speed control in electric locos, but it may operate differently.

2) My understanding is that it only uses electrical power to the traction motors, but I will try to confirm if that is correct. [ @Coolhand101 may know ]
Most locos so fitted did not have dynamic brakes, but I will try to find out if the system could apply the air brake if needed.

Links to some instructions are given below. From these, this is what I assume needs to happen:

(1) Driver moves throttle to OFF and uses brakes to stop train or reduce speed to very low.

(2) With throttle at OFF driver moves reverser from "Forward" to "Engine Only" (=neutral in ORTS) and selects slow speed with slow speed controller

(3) Driver moves throttle from OFF to ON

====== Train operates at slow speeed with engine at idle until ========

(4) Driver moves slow speed control to OFF - train speed then increases to what it would be with the throttle at ON (engine at idle) if there were no slow speed control (6-7mph)

(5) Driver then moves throttle from ON to OFF, then moves reverser from "Engine Only" (neutral) to "Forward" and then moves throttle from OFF to ON.


I will try to confirm if this is correct. There is some description of operation in these:
