I created a TARGET Script for the Thrustmaster Warthog Throttle to control the GP38-2, SD40-2, GP40-2, AC4400CW engines in Train Sim World. Yes I currently only have TSW: CSX Heavy Haul. No guarantees it will work with other engines. Most the commuter engines from the other DLC have combined throttle/dynamic brake levers. If those levers are similar to the AC4400CW throttle/brake lever, then this may work, but probably not perfectly. Modifying the script for other engines isn't difficult, so when I get other DLC's, I will update the script. Hopefully, Dovetail Games will add analog game controller support to TSW eventually so that a kludge like this isn't necessary. If you desire such a feature, let them know. You can download it here. Read the _README.txt file and the PDF documentation for details and usage. http://akhara.com/drop/TrainSimWorld/TSW_TARGET_Script_Drakoz_v1.0.zip The script isn't perfect as it is mapping axes to perform keypresses. Also included are some profiles for the Saitek Throttle Quadrant and the Throttle Quadrant that comes with the Saitek ProFligtht Yoke. You can control the reverser, throttle, independent brake, dynamic brake, and automatic brake all with the Warthog Throttle (Warthog Joystick not needed). The Warthog Left Throttle axis can be set to control all 3 brake levers with a toggle switch. But the Saitek profiles take care of the independent and automatic brake levers so you don't have to task swap on the Warthog Left axis. If you have wanted to see advanced programming in TARGET, this is an excellent script to learn from. It isn't hugely complicated once you see what I did, but it does go way beyond simple MapKey() commands.
