Metra EMD F40PH-3 & Nippon Sharyo Gallery Cab Car Physics Mod V1.0

[FanRailer]

This is the Chicago & Southwest Productions Metra EMD F40PH-3 Locomotive & Nippon Sharyo Gallery Cab Car Physics Modification pack version 1.0

In order to utilize this freeware physics upgrade, you must have purchased the "The Racetrack: Aurora - Chicago Route Add-On" pack available at Steam: http://store.steampowered.com/app/258648/

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 mod pack. That full mod pack MAY be available separately from this one in the future once I have acquired sounds. Stay tuned.

The purpose of this pack is to adjust the physics performance of the EMD F40PH-3 locomotive and the associated Gallery Cab Car.

SIDE NOTE: To obtain Metra logo and decals for rolling stock, download this pack: http://railworksamerica.com/index.php/d ... ccessories (http://www.facebook.com/groups/720469151375805/files/)

List of general changes; specific changes for each specific locomotive located below:
1. Modified tractive effort and braking effort curves.
2. Modified power ratings @ alternator and @ wheel.
3. Modified cab car fuel capacity.
4. Removed coupler slack.
5. Changed brake pipe normal pressure from 90 PSI to 110 PSI. Actual Metra equipment runs with 90 PSI in the brake pipe, but the game engine runs the brake gauges a little better if the pressure is set to 110 PSI. In addition, there is an issue with custom built consists with the cab leading not taking power if the brake pipe is set to 90 PSI. A future edition of this physics mod will be released to correct this problem; at which time, we will revert back to using the 90 PSI brake pipe.
6. Modified the cab car so that it does not provide tractive effort to the train set; only the locomotive applies tractive effort after the installation of this mod.
7. Adjusted cab car HUD ammeter upper limit from 1500 to 1800.

Version 2.0 of this mod will include a signature JohnS brake fix that will correct the air gauge functionality and allow a return back to the prototypical 90 PSI brake pipe rating.

NOTE: Although the F40PH-3 locomotive comes default with a neat HEP mode toggle ability, this only affects engine RPM; tractive power is not affected, so I have included two sets of physics that the user can switch between. Specifics are listed below for each set of physics. Instructions on how to perform the switch are included in the owner's manual, also located below.

Technical specifications:

1. EMD F40PH-2 (EMD 645; 3200 THP; no HEP)
a. Starting tractive effort of 65,000 lbs (289.1344 kN)
b. Continuous tractive effort of 38,240 lbs (170.1 kN) @ 16.31 mph
c. Dynamic Brake effort of 35,000 lbs (177.93 kN) @ 55 mph; extended range sawtooth curve between 55 mph and 36 mph. Fade to 0 lbs @ 0.5 mph (not in use)
d. Wheel horsepower of 2,850 hp (2,390 kW) @ 30 mph
e. Maximum speed of 103 mph
f. Engine RPM range = 410 - 900
g. RPM change rate (rpm/second) = 18
h. Fuel consumption range (gph)= 4 - 155
i. Weight = 260,142.8 lbs (118 metric tons)
j. Fuel capacity = 1500 gallons
k. Max traction amps = 1785
l. Max brake amps = 700 (not in use)

2. EMD F40PH-2 (EMD 645; 3200 THP; 500 kW HEP [7 - 11 cars])
a. Starting tractive effort of 65,000 lbs (289.1344 kN)
b. Continuous tractive effort of 38,240 lbs (170.1 kN) @ 16.31 mph
c. Dynamic Brake effort of 35,000 lbs (177.93 kN) @ 55 mph; extended range sawtooth curve between 55 mph and 36 mph. Fade to 0 lbs @ 0.5 mph (not in use)
d. Wheel horsepower of 2,210 hp (2,390 kW) @ 22 mph
e. Maximum speed of 103 mph
f. Engine RPM range = 410 - 900
g. RPM change rate (rpm/second) = 18
h. Fuel consumption range (gph)= 24 - 155
i. Weight = 260,142.8 lbs (118 metric tons)
j. Fuel capacity = 1500 gallons
k. Max traction amps = 1785
l. Max brake amps = 700 (not in use)

NOTE: Because of they way the game engine works, subbing in these real world values does result in slower high end acceleration. Run the locomotive with the non-HEP physics if it bothers you that you can't make it to track speed.

IMPORTANT; Install Instructions:

1. Locate BNSFChicago (C:\Program Files (x86)\Steam\SteamApps\common\RailWorks\Assets\Barnez\BNSFChicago)
2. Open TS2015_Metra_EMD_F40PH_&_Gallery_Cab_Car_Physics_Mod_Pack.7z
3. Drag the file folder from the .rar in step 2 into the directory you opened in step 1.
4. The installation should be complete. Run TS2015 to check.
5. If installation is botched or does not work, to back up to original files, delete the folder from step 3.

Owner's Manual:
Once installation is complete, the pack defaults to using the non-HEP locomotive's traction physics. In order to switch between the HEP and non-HEP locomotive physics, follow the steps below:

1. Locate the following two directories:
1a. C:\Program Files (x86)\Steam\SteamApps\common\RailWorks\Assets\Barnez\BNSFChicago\RailVehicles\Diesel\F40PH\Chicago
1b. C:\Program Files (x86)\Steam\SteamApps\common\RailWorks\Assets\Barnez\BNSFChicago\RailVehicles\Passenger\NSbilevel\NSCabCoach\Engine
2. Within each of the two above directories, you will see two more folders labelled "HEP+" (HEP version) and "HEP-" (non-HEP version).
3. Once you've chosen which version of physics you want to run with, enter the respective folder, copy the contents inside, return to the previous directory, and paste the contents that you copied. Overwrite when asked.
4. Physics set swap should be complete; run TS2015 to confirm.
5. Expert users can run multiple physics sets at the same time if they choose. The key is to make one locomotive (driver) a HEP locomotive, and the other (no driver) a non-HEP locomotive. I'll let these expert users figure out how to do that.

NOTE: When trying to run a career scenario after installing any physics mod, you will have to bypass the "track.bin" error message that pops up by pressing "F2", then hitting save. The scenario will then be playable.

Thank you for downloading and installing.
Enjoy =)

Is this the same thing as is posted in two other places? I'm confused.

Thanks, FanRailer, for your relentless pursuit of true train simulation.
Do the passenger locos use graduated release?
What about the cabcar with its many scripted functions? Its automatic train brakes are still very abrupt.
Does the independent brake have a bail off position, the handle won't stick in any application, but can pressed down in release?

Some general questions that might be discussed:

i think you should consider adding 0 Psi in the CylinderPressureForBrakeToCutPower in the simulation.bin, so you can apply power against the brakes. Useful in flying starts necessary to maintain schedule with so many stops.

I am not entirely sure the <Distributor> section should be used instead of <TripleValve> etc.

Also what is your opinion of using a proper 26L service arc of: Release (0.00), GraduatedSelfLapLimitedHolding (0.05) , FullService (0.55), Suppression (0.60), ContinuousService (0.65), NeutralHandleOff (0.85), Emergency 0.90), simulating the escutcheon plate through "clunks"? It helps to reduce digital sensitivity to 0.25 or so, when operating the train by keyboard the handle doesn't move so fast.

I usually post an abbreviated mod announcement in the thread for the DLC discussion, as some people who follow that forum MAY not follow this one. Those abbreviated posts always redirect to the main release thread, which is in this forum.

I will defer the brake corrections to JohnS, as he is more proficient with those commands in the code than I am.

Very well, the braking stuff can wait. The EQPressure error is returning with the cabcar as well. Very annoying core engine bug.
Those fancy colourful notches only work when the handle rests in notched positions, which is unprototypical. Unless scripted, like in the virtualRailroads advanced locomotives.

How does your power curves work out? The resulting HP/ton is rather low for a full capacity rush hour train with only one F40, also supplying HEP.
You really need to hit the throttle to pick up speed fast enough.

In the 26L brake valve there is small notches for minimum service, suppression, and handle off. I don't have anything with the "advanced" braking so I can't compare this to that. I will do my best to make everything work as intended. I haven't gotten this add-on but I hope to soon.

Thank you lots for the creation of this; I would also like to run the Tri-Rail F40PHL with physics sets similar to this one (Driver and no-driver variants with separate HEP/no HEP)
