I have a thread I started after finding one in an Edward here
https://blueplastictracks.com/showthread.php?tid=3842
I don't think I ever opened the front of Edward to know if he had a capacitor or not. I know the Talk n Action engines also use them, although that makes more sense to me where back-EMF from the motor would hit the talking circuit board, not just the battery. Seeing as this is also the timeframe of the Talk n Action engines I wonder if perhaps they borrowed the fuse and cap idea to implement some additional (if mostly unwarranted, as discussed in the other thread) safety precautions, and dropped them after they stopped stocking fuses/caps when Talk n Action was replaced or for cost reduction.

I have a website where I have been writing about and photographing many of the sets and pieces that I find interesting.
