Hi Gerry,
If you let me know once they're uploaded, I'll add this as a news item on www.openrails.org

The files have arrived on TrainSim.com and I've added a news item on www.openrails.org

Well done, Gerry

Thank you, it was an enjoyable learning experience.

Unfortunately it looks like the link on openrails.org doesn't work... it says there were no search results found.

I did find the file by searching (for the record, its name is "orts_standard_engines.zip").

Yep.

Is there any way to confirm that the .inc file I have installed is working correctly within the game?

I noticed some changes in the data on the HUD display.

Yep there is...when I first starting making and testing them...I was suspicious that they weren't working. So I introduced an obvious error in the path string, an error showed up in the log...alternatively you could remove a bracket from the file and see what happens in the log.

It's hard for me to say for certain they are working, not knowing specificially how each user is integrating them into their trainset.
I use them in the Common.inc folder in conjunction with OpenRails folders in the wagon and locomotive folders in the TRAINSET folder.

So for example, this is an include engine file from an OpenRails folder that has a path string to the "Std_Eng_SD24_bb.inc" file and also brake and coupler files. By introducing any error into the path strings, you should generate some sort of warning or error in the OR log.

Also by introducing an obvious error into the Std_Eng file ( missing brackets, nonsense data or number, you should also generate an error in the OR log.

The locomotive HUD data should show the RPMs found in the Std_Eng file, fuel consumption, and other data.
However, they may not be exactly the same, as the OR interpolator will find values between those given in the Std_Eng file.
To see if they were working I purposely made the power tab have an entry that did not increase as it should have...entered a nonsense value that was considerable lower then the previous notch...OR log generated an interpolator error of a non increasing value.

Hi Gerry,

I have been watching the hud carefully, and have just noticed a problem with sd40-2's
They show up as 2400hp in the hud.
I have 3120hp in each of the eng files.
Route: Tehachapi Pass II
Activity: SP Unit train

If I rename the openrails folders to notopenrails, I get 3000hp traction power in the hud.

**=FI=Ghost** · 05-16-2019, 05:50

My friend,

Can you make standard engine file for ES44AH locomotives?

I have noticed this on a couple of mine as well.

Derek, I think this is the problem with the advanced adhesion model we've spotted before. The advanced adhesion model could use more work --- or it could be something I've bungled in the Std_Eng file...give me some time to make some tests.

As you know, that's to be expected...the HP and all other values found in the MSTS file will then be reflected in the HUD.

I believe so, can you confirm this data I have gathered...my sources are scarce...
1. Locomotive mass: 432000lbs Adhesion 47.7% = 206064lbs STE
2. Traction HP 4445 GrossHP 4545 (??) <<<< this I don't know
3. Computer software to boost CTE up to 33,000lbs per traction motor ( 6 motors ) = 198000lbs CTE
Sound about right?

**=FI=Ghost** · 05-16-2019, 09:49

This is what I have in my Table:

GE ES44AC High Adhesion (GE GEVO-12; 4700 GHP)
a. Starting tractive effort of 198,000 lbs (880.8 kN) up to 7.519 mph.
b. Traction horsepower at wheel is 4,390 hp (3,276.12 kW); efficiency rating of 93.4%.
c. Max Dynamic Brake effort of 117,000 lbs (520.442 kN) from 16.51 mph to 3 mph; linear fade from that speed to 0 lbs @ 1 mph.
d. Dynamic Brake horsepower at wheel is 5,145.6 hp (3,840 kW).
e. Increased weight of 195.954 metric tons (432,000.1884 lbs).
f. Maximum speed of 75 mph.
g. Fuel consumption @ notch 8 is 210 gallons per hour.
