Lionel air whistle problems

Thanks.  This looks very interesting.  Might just help those "pesty" whistles.

Since I am on vacation, I have done some additional research. In re-reading the thread that I previously posted, I learned that the Electric RR site has a "Hobby Corner" section that contains three projects that relate to the whistle controller:

Post War Whistle Controller

 Used by the AC/DC Commander, this circuit will come in handy to operate your post war whistle under Command Control.  A low cost, simple to construct, fun weekend project.

  Teledyne Coupler Controller

 Conventional control of your coil couplers.  Activate the couplers on your post-war switchers with the "Horn" button!

  Solid State Post War Relay Replacement

 A combination of the above two projects, this is a solid state version of a whistle / horn relay.  Tired of "tweaking" that relay to pull in or release?  Here is your solution to a cranky relay!

I am including a link to the last one in the post for anyone that wants to try this.

If I get one of these working, I will let you know!

Hi Guys,

I would like to replace the relay for an  older Post War air whistle with an electronic version.  In doing research on this topic, I ran accross this thread. http://cs.trains.com/TRCCS/forums/p/76446/916197.aspx#916197

Unfortunately, either the schematics are not at Hobby Corner (now located at discover circuts)  http://www.discovercircuits.com/DJ-Circuits/daj-main.htm  or I don't know which one to use.

I don't beleive that electricrr has their replacement product available anymore. 

So, my questions are 1) is there a schematic available  and 2) if not, can the Lionel electronic relay uses in their new air whistles be adjusted for use with the old post war whisle? The reason I ask this is that the new air whistles use DC can motors..

Thanks, for your help.  Dave
