These sound like TAS EOB issues. The 2-10-2s may be TAS SAW boards too. Continuous whistle usually means the board is not seeing the speed sensor on the flywheel. If they all have EOB boards you can try reprogramming them including the key strokes for startup, etc. The manuals for TAS EOB and TAS SAW boards can be found in last sticky at the top of this forum.
