Modify engine physics

[wlenz781]

Is it possible to modify an engine so that it goes faster? I want to recreate a Tri-GP49. In order to do this, I want to adjust the GP40-2 Pack so that its top speed is the same as the NJT GP40PH. Any advice will be greatly appreciated.

Yes, I have just about the same question, except instead of speed, I am looking for tractive effort.

I've been using the ex-MSTS Triplex as a B&O EL Class 2-8-8-0, which is simply replacing the "tender" with a standard Vanderbilt one.

My only issue is that the lead engine counts as a wagon, so it generates no power, while the back end is another "engine". This means my B&O Mallet is only as powerful as a 0-8-0 switcher. It can't even pull 60 55-ton hoppers loaded with coal on the B&LE route without a helper (I used the Smokebox Consolidation).

My solution is to take the middle section (with the cab and boiler), and double the strength value of the second set of cylinders to compensate, but I don't know how to change those values.

Without looking I think you need to look in the simulation folder.

It seems that there is no simulation folder and instead in the main engine folder there is ORW_EngineScript.lua. I am guessing this is the main simulation file, except what program do I use to open and edit it?

A plain text editor.
Lua is the source code for the scripting engine.

I can't speak for TheRFan, but I have managed to solve the issue myself, with the help of some youtube tutorials. I opened the FanRailer GP40PH Simulation bin and the GP40-2 Simulation bin side-by-side and modified the values for all the variables. I copied over the dscv files and replaced them. The result, a GP40-2 that will do 99.9mph while pulling 4 passenger cars.

Yes I just used notepad and it seemed to work.

Ok, I think it might be just a bit different for me since it is a steam engine but I guess trial and error is necessary.
