Reply to "Lionel KW whistle controller issue"

The photo explains a lot. There is no whistle relay... it's electronically triggered:

That loco/tender combination with the DC motored whistle is not pulling enough current through the diode, and hence a DC component/offset, to stay energized in the "hold" position of the KW whistle control.
