GE Evolution Series (ES44AC, ES44DC, etc) Physics Mod Packs

[FanRailer]

The GEVO has been released so many different times in different packs (yet all have identical physics, irregardless of model), it's going to take a while to release mods for most of them. Here's a start:



This is a Kuju GE ES44AC Physics Modification pack (One of perhaps several). The test you will see in this video consists of 3 locomotives accelerating a 60 car Autorack freight train up to 75 MPH before utilizing only dynamic braking to stop. Since the physics of both versions are relatively similar (only starting TE and weight is different), I elect to show you the High Adhesion variant.

In order to utilize this freeware physics upgrade, you must have purchased the "US Loco & Asset Pack" pack available at Steam: http://store.steampowered.com/app/208306/

This is a freeware pack; in no way is it to be used for commercial purposes. You are free, however to further modify the physics enhancements found in this pack for personal use if you so choose.

THIS IS NOT A SOUND UPGRADE PACK. Physics adjustments made around the existing sounds.

The purpose of this pack is to adjust the locomotive weight, motor amperage limits, and traction and braking effort values for more realistic operation.

This pack includes the ability to switch between the standard ES44AC and the high adhesion ES44AC. More details below.

General Parameter Change Log:
1. Changed HUD ammeter function so that it displays tractive/braking effort in thousands of pounds. This means that if the HUD ammeter reads "157 Amps", the locomotive is putting out 157,000 lbs of tractive effort. Conversely, if the HUD ammeter reads "-34.52 Amps", the locomotive is putting out 34,520 lbs of dynamic braking effort.
2. Adjusted tractive effort ratings and curves for individual locomotive variants based on the specifications listed below.
3. Adjusted dynamic brake effort ratings and curves for individual locomotive variants based on the specifications listed below.

Specific horsepower and tractive effort ratings used in calculation for individual locomotive variants:
1. GE ES44AC Standard Adhesion (GE GEVO-12; 4700 GHP)
a. Starting tractive effort of 180,000 lbs (800.68 kN) up to 8.2714 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 188.7 metric tons (416,008.02 lbs).
f. Maximum speed of 75 mph.
g. Fuel consumption @ notch 8 is 210 gallons per hour.

2. 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.

IMPORTANT; Install Instructions

1. Locate the following directory: (C:\Program Files (x86)\Steam\SteamApps\common\RailWorks\Assets\Kuju\RailsimulatorUS)
2. Open Railworks_GE_ES44AC_Physics_Mod_Pack.rar
2a. Before proceeding to step 3, make sure your "Kuju" folder is NOT set to "read only". You can change the folder settings using the properties function. IF the "Kuju" folder is read only, the files will not overwrite existing files when you attempt step 3.
3. Drag the file folder from the .rar in step 2 into the directory you opened in step 1. Overwrite if asked.
4. The installation should be complete. Run TS2015 to check.

User's Manual:
Upon installation, the pack defaults to using the high adhesion ES44AC Physics. In order to switch physics, follow the steps below:

1. Open the following directories:
a. "C:\Program Files (x86)\Steam\SteamApps\common\RailWorks\Assets\Kuju\RailsimulatorUS\RailVehicles\Diesel\ES44AC\Black\Simulation"
b. "C:\Program Files (x86)\Steam\SteamApps\common\RailWorks\Assets\Kuju\RailsimulatorUS\RailVehicles\Diesel\ES44AC\Black\Engine"
2. In each of those directories, you will see two folders (one for each set of locomotive physics):
a. "Standard Adhesion"
b. "High Adhesion"
3. Once you choose which set of physics to use, open the respective physics folder in both directories from step 1.
4. Copy (CTRL + C) all files you find in the opened folder located in directory 1a.
5. Proceed back to directory 1a and paste (CTRL + V) the copied files into the directory; overwrite when prompted.
6. Copy (CTRL + C) all files you find in the opened folder located in directory 1b.
7. Proceed back to directory 1b and paste (CTRL + V) the copied files into the directory; overwrite when prompted.
8. If the previous 7 steps were completed properly, the physics swap should be successful; run TS2015 to check.

But BNSFs ES44ACs and DCs are only 416,000 lbs.

So you're saying, the manual lies...

[BNSFdude]

I run Evos 5 days a week as a Hostler. They all say 416,000 lbs in the cab. That's DCs, ACs, and C4s.

I run Evos 5 days a week as a Hostler. They all say 416,000 lbs in the cab. That's DCs, ACs, and C4s.

And I don't doubt that, but I'm going to stick to the 420,000 weight; for the extra little boost in adhesion.

[BNSFdude]

I also wanted to say that a GEs HP is rated at wheel, not sHP. A GE puts out 4600 shaft HP on both the FDL and GEVO. The ACe/M-2 is about the same with 4500 sHP, but rated at 4300 wHP. This takes into account transmission loss and HP lost from auxiliary systems.

[BNSFdude]

These are from observations of the locomotive monitors while running. GEs show shaft HP of the engine and HP per traction motor. When working on a drag, I observed 4380 HP total between the 6 motors of a ES44AC. The Engine was putting out somewhere between 4600 and 4700 HP depending on what systems turned on or off, because as you know, Horsepower is a measurement of Work.

Ok. Thanks for the info. I'll update accordingly for a re-release next weekend here.

Could FanRailer have a manual for ballasted locos?
Or, could one weight be referring to gross weight while another refers to net weight?
IE dry vs wet weights.

I'm thinking that may be the case. The difference in those weights is always very small.

I also have to note that I'm generally using a transmission efficiency rate of 90-93% from the alternator to the wheel. So if a GEVO puts out 4700 hp at the alternator, that's around 4370 hp at rail, and if an ACe puts out 4500 at the alternator, that's around 4185 hp at rail. I'm also finding tractive effort curves and data for international versions of the SD70ACe, where extrapolation of the graph data indicates maximum wheel hp somewhere closer to 3900 hp. Also, I've seen TE curves for the ES44AC where extrapolation of the graph data indicates maximum wheel horsepower of just over 4000 hp. So basically, what I'm saying is that there's a lot of conflicting data out there, and it's not the easiest to say which is correct.
