Hello!

There is a control that does not work, according to OpenRailsLog.txt is because it does not exist:

ORTS_HELPERS_DIESEL_ENGINES_STATE

However, the one that controls the main engine does exist (and works):

ORTS_PLAYER_DIESEL_ENGINE_STATE

We always talk about the Testing version. Is there any way to make it work? Thank you!

Hi again!

Another cockpit control from the old MSTS (present in Kiha 31) is:

ENGINE_BRAKING_BUTTON

Would it be possible to implement it as well? Sorry if I'm asking too much...

Thank you!

The interesting question here is what is it supposed to do in the Kiha 31? Since the Kiha has a hydro-mechanical transmission, I rather suspect that it is a hydrodynamic brake and as such would be best represented using dynamic braking parameters.
Another type of engine braking was to use something called "exhaust pressure" braking. This was quite rare on railway vehicles though I believe it was included in some early Italian railcars with mechanical transmission. (Probably the best use of the 'engine braking' button, but without some technical data about the real thing it may be difficult or impossible to include in Open Rails.
The third type of engine braking is what you see in an old fashioned motor car with a mechanical gearbox. This existed in some older railcars and locomotives that included a friction clutch but did not include a freewheel mechanism. It should be possible to model this as part of the OR mechanical gearbox.
So to make that feature work, we really need to have a clear understanding of what it does and how it works. If anyone can help with details they would be much appreciated.

Hello, Darwin.
I see some inconsistense with your list at post #1:
Eq res&Main res perhaps are not controls; horn&sanding I believe are not deals&gauges as well as throttle.
Or did I miss something?
The list looks very useful reference though-Thanks for efforts.

What about bailoff button and multistate displays?

As Peter made it's pressure independent from MR, the question returns to be actual, isn't it?

Sorry: sanding is gonna be a display, but sanders are control, that's correct.

You are correct. Some things are on the wrong lists.
With regard to MR and MR pipe it is now possible for these to be different. Bail Off would hopefully be developed when independent locomotive brakes and mixed braking are reviewed at some future date. At present there are a lot of errors and inconsistencies with the way that locomotive brakes (as opposed to train brakes) work. One question I have asked before and not received an answer to is does such a thing as a "Bail Off Button" exist in real life? If it does then it would be good to have some information. Looking at braking systems from USA as far as I can see "Bail Off" is a position on either the independent brake controller or the train brake controller.

MSTS manual says, that function connects engine's shaft to wheels at first gear, while throttle is minimal.
Such occurs with buses, equipped with mechanical gearbox: driver sets 1-st gear, depresses throttle pedal, then-clutch control pedal.
Diesel or benzine engine resists wheel rotation, so speed is decreased very fast without breaks engagement.
This is called engine braking (motor, but not locomotive has been meant)

Another type of engine braking was to use something called "exhaust pressure" braking.

Some of big dump trucks have valves on their exhaust pipes, propelled by pneumo-cylinders. I asked about their purpose and the answer was "mountain retarder" On long descents, driver turns motor off, closes those valves, so motor pistons work as dynamic brake, compressing air in motor's cylinders. This mode saves brake shoes and decreases wheel skid/blocking possibility, when truck descends with heavy load.

But, since KIHA have hydraulic transmission, there may be hydro-dynamic braking, as you said.

Yes, you have just overtook me, my dear mate:
It's long time, I'm thinking about overlay with another 2-framed *.ace for implementing the first position for our 254 independent brakes valve:
First frame is transparent (shown all the time, while bailoff button is not pressed), so it does not obstruct the *.ace of loco brake lever with frames of II to VI positions (correspond to Running and four self-lapping 25,50,75,100% independent brake application notches)
But as bailoff is engaged, the second opaque frame, with valve's handle at I-st position is shown, covering valve's 5-frame *.ace

I doubt, however, that placing such two controls (having same frame dimensions) to the same place of the cabview will not cause any issues.
How can we guarantee, the bailoff animation will always overlay (cover) valve's handle animation *.ace?
Furthermore, you've mentioned mouse control problems already.

some AC electric locos had a Notch Indicator

DC may have it too:
In case of automatic controller instead of manual.
Then cab control has very few notches (may be 0,M,1,2,3,4 or Off,-1,0,+1,Auto run-up) so the driver must have the gauge to verify controller's real state (controller has 30 to 50+ positions)

Overlay of the scale to show zero if throttle is moved but not in either forward or reverse

Neutral reverser's position (handle can be removed there) locks-up throttle lever, so it usually can't be moved.
Some diesel locos have fourth "idle" revercer's position, other has Master control switch for moving unlocked controller handle forward without bringing locomotive to running.

a second MR needle adjusted for a maximum pressure of 100 PSI

Great trick.
But if you'll set scale range between 0 and 100, would the needle stop at 100, when actual pressure will be higher?
If yes, there will be no wrong behavior of needles.

As Peter made it's pressure independent from MR, the question returns to be actual, isn't it?

However, as we know now, the better way would be implementing the new gauge, dedicated exclusively to Feedind pipe pressure.

[Weter]

Should we specify types as two\three state gauge/needle?

What about a dummy function? I only need a click button to display the graphics, right now I'm using:
TwoState (
Type( CAB_RADIO TWO_STATE)
position ( 2 123 55 110 )
Graphic ( scheldule_C.dds )
NumFrames ( 2 2 1 )
Style ( ONOFF )
MouseControl ( 1 )
)
Frame 1 is the button, frame 2 is the button and the schedule
but i can only have 1 since they interact.

So a dummy function witch only function is to display the graphics that don't interact so you can have 10 individual buttons.

Edit: I'm now using ORTS_GENERIC_ITEM1 instead of Cab radio in this pop-up timetable.
