I'm sure that in the past, Frank's locomotives were created in TRS2004, BUT, the bogeys were done in TRS2006. When you've downloaded all the dependencies, you must check to ensure that the trainz build is 2.4 on everything if you are using that version and to change the trainz build on the bogeys from 2.5 or 2.6 and to change the bogey in the config.txt to read something like this :-
bogey-1 <kuid:-12:3535>
bogey-2 <kuid:58377:50012>
bogey-3 <kuid:58377:50013>
Now, if you're still having problems in getting Frank's locos to work, post back here, OK ??
