I can't answer C.W.'s question. But going a little off-topic, I'll share that Pullmor motors, and the "fuzz" they put on our TV is partially responsible for me becoming a huge football fan.
When I was in grade school during the 1970s, our trains were only set up at Christmas time, and then in the den where the TV was. On Sundays, my grandpop would come over. He and my dad would watch football on broadcast TV. (Cable was still several years away.) We weren't allowed to run trains during the game because it caused "snow" in the TV picture. There was nothing else to do, so my brother and I watched football too. We learned about the game, and today we're both big fans. So I guess it's a good thing that MPC didn't put capacitors on its motors. And I still think of football and trains as fall / winter sports!!
