John,
The final file I used was a regular PS2 sound file, not an upgrade file. I couldn't find one that synched up the wheel rotation to the chuffs, to my liking anyway. I only tried 4-5 files so there may be one that does the trick.
I noticed you asked more or less the same question on one of my old posts:

Barry's reply was that to get things like marker light function the file has to come from an engine that originally came with lights (at least I think that's what he meant).
Also, if an engine that comes up doesn't have the 5 volt or 3 volt icon showing, can I use the file? How do I know if it's 3 volt or not?
If you click on "SERVICE" then "PRODUCT FILES AND DOCUMENTS" then type in 2-8-0, there's a number of engines that come up that don't have the 3 or 5 volt icon.
The one I first mentioned above (30-1159-1) shows both a sound file and an upgrade sound file icon, but no 3 or 5 volt icon:

Engine 30-1159-1 is the 2nd one down the list.
STOP!!!
When I clicked on the upgrade file to save it, the file name indicates it's a 3 volt file. The original PS2 file name only says "final MTH" file, no volt indication is given. So just because there's no 3 volt icon doesn't mean there's not a file that will work (Did you or Barry say at one point that ALL upgrade files are 3 volt?).
Is the only way to find out if the marker lights are on this 3 volt upgrade volt, is if you download it and try it out, or will the engine writeup ALWAYS indicate operating marker lights?
I did notice marker lights mentioned in the writeups of Premier engines, I'll most likely try another one of them, but I hate to have to do a bunch of downloading trying to find one that has in-sync chuffs and all the other lights (markers) and sounds (generator spooling) I want.
