Unwanted whistle
By: smserv Date: January 11, 2013, 12:15 pm

My post-war tender whistles fine when pushing the whistle button
on my ZW transformer. However it intermitantly whistles in short
bursts while running around the track when no whistle button is
pushed. Any ideas why this happens and how it can be rectified?

Is it possible that the relay inside the tender is rattling
around loose and causing the switch contacts to close
momentarily? A loose wire or some other object flopping about
inside? Does it happen more when the train is moving faster?

With a PW or MPC era tender you will want to open it up and
check the insulation that is under the soundboard.
If it is disintegrated/worn out, it will allow the board to
short out, eventually it will burn the board up. It's easy to
replace it with either a piece of cardboard/posterboard or a
piece of foam. I had to replace the insulation on one of my
tenders that had a similar problem.
