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/download-library/accessories?view=document&;id=1858:metra-signage-logos&catid=24:accessories (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.

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 =)
