Re: Looking for parts

The K-line parts dept. is (919) 942-1116

 

I have had no problems activating my conventional locomotive wistles on the layout.  Yes, when you press the horn/Whistle button it should send the proper DC signal down the center rail for the whistle.  I don't know which one, but I do know that the whistle and bell signals are opposite one another.

 

For instance with a locomotive that has both a bell and a whistle you can switch which one is activated by switching the polarity of the "D" cell battery in a postwar whistle/bell button.

 

If Hugh's whistle wont sound on the club layout with the whitle button try the bell button to see if that activates it.  The wires could be crossed inside the tender.

However I have not been successful in finding a replacement resistor (and the fiberous element covering it) anywhere on the web. Could someone direct me to a supply for these parts? The engine is a K-line, and I wrote the website for advice but so far no answer.

After disassembling, testing, reverse engineering, etc. I found out that the whistle actually does work if the transformer connections to the track are reversed. In a conventional whistling tender, the whistle is activated by the superimposed DC on the track using a DC relay. The polarity of the relay was not significant.

When the whistle switch is closed, is the center track supposed to be positive with respect to the outside tracks? Is that the way the club layout is wired? Do the club command controls actually apply conventional whistle signals to the tracks? (His whistle didn't seem to work on the club layout either.)
