Hopefully they'll have ARN. Worst problem is I understand scripting the way a monkey understands bananas. See a banana on a tree it's not to hard to pick it and figure out how to peel and eat it, but wouldn't have the first clue how to plant and cultivate a banana tree. I'm using an old wulf9 / norfolksouthern37 script that has sound effects, marker lights, class lights, beacon, fan animation effects, and an automatic banana peeler, also includes automatic running numbers. Paul's NH Class DERS-6 F-M H-16-44 Undec,<kuid:520526:1530> has a marker light script, took me the best part of a day to get the two scripts to stop fighting with each other. Not sure if I have it right yet, it looks like it's working correctly but I have no idea why.
1691 is the trailing loco of that pair, got marker lights on, 1622 is lead loco so marker lights are off, on for the one behind it.
Headlights work the right way and markers go off depending on which end is coupled. One problem;
C&NW traditionally had big numbers painted on the side of the long hood, nothing but the bar and bell logo on the side of the cab. Gotta work with what you have, made the logo as big as would fit between the window and number. Looking in an old C&NW book there were apparently 65 of these made, C&NW owned 59 of the 65.
