Jim,
Yeah, I still like the transformer. And thanks for your help.

Ed, the only suggestion I can offer you is to try some throttle jockeying when you want the whistle to blow. As you might have noticed, the trains will slow way down when the whistle button is pressed. Stepping up the power when you blow the whistle will stop the slow downs and may be enough to sound the whistles.
In spite of the air whistle issue, I believe the MRC PPD is an excellent value for the money. 275 W, dual volt and amp gauges, and two train throttles, direction, whistle, bell controls, for just over $200 at Charles Ro (where we got ours).

LocoPops Is your air whistle a modern can style or old style with an open framed motor? I talked to a fellow at MRC about this issue when I got mine. He told me that the unit was designed primarily with the new sound systems in mind. It does work extremely well with new electronic systems. But with air whistles, it's hit or miss. Since I tuned up my post war air whistles, they work at lower voltages. Jim

These are both modern air whistles (Pennsy Flyer and Wabash).

I have the electric solenoid air valve, if you use CO2 cartriges you will also get smoke. all we need is someone to machine out the whistle. probably the hardest part. I have a live steam loco and it sounds good, but a little high pitched.

Thanks, I will give that a try!
On my roster nothing beat my Lionel Century Club NYC Hudson. MARTY E, one of our forumites has it on his webpage and when I heard it, it just blew me away. I had to get one. Check it out .....

I've got an MRC PPD and love it. Modern electronic sound systems from all manufacturers work best with it. By that I mean those with recorded sounds as opposed to the mechanical whistles of the past and present.
When I first got mine, it wouldn't blow an air whistle unless, as you noted, it was at the higher end of the voltage range. But after servicing my post war air whistles, I've noticed that they will work starting at 12 volts or so. Some work better than others.
OK, speaking of whistles... I've got an MRC Pure Power Dual and I like it very much. But my two main trains both have air whistles. And it won't blow either whistles unless the throttle is turned high enough to send the train flying off into space!
For now, I've rigged up a whistle station controlled by both a button control and an infrared trigger. However, I'd like to use the tender whistles. They both have a really nice sound.
Is there anything you can do to make the tenders work with the MRC...at a realistic, safe speed? Also, does anyone know which sound system is most compatible with this transformr?
Thanks.

It sure does. I've wondered about the grey and black colors too. Thanks.
ps-this forum is full of guys who know this business inside and out!
I'm a little confused about those sheet metal tenders. I thought they were pre-war, like the other tinplate stuff. But recently I saw one that the owner claimed was from 1946 or 47. Can anyone clarify the time period? Thanks.
