I have created a clone of the AEM-7 that works with Rail Driver (that's the good news) unfortunately the Alerter is frozen in the activated mode (that is the bad news). Apparently the Virtual Throttle and Virtual Brake are what interfere with the Rail Driver, but they are also what is read by the script that controls the Alerter, so when I replaced them in the bin file with a standard regulator and train brake the Rail Driver works but the Alerter is constantly on. What I did for my installation is to rename the sound file for the Alerter (T_Cab_TrainStopAlarm.dav) to xT_Cab_TrainStopAlarm.dav to silence the alarm.
If people are interested in trying this file out with their Rail Driver let me know and I will either send individual copies out, or maybe include the file in a post.
Note - this file is the engine bin file only - you must already own the AEM-7 for it to work.
