I took the TrainBeat demo song and put the wave files into Adobe Audition and I do not see the 2 bar ending.

If I understand you right, you saw the 2 bar ending in SoundForge but that ending does not play in BIAB.

I don't see a 2 bar ending. I see exactly what it plays in BIAB and, yes you are right, it stops early.

See attachment screen shots of both BIAB and Adobe Audtion.
