I did not have WD40 on hand so I used a light oil I use on trains in general to coat the rails.
And I used it very sparingly. No go.
I gave the track a good cleaning with rubbing alcohol and that seems to give the best results against sparks.
I also put a few lead weights in the tender which seemed to help.
My K5 did not come with the jewels in their respective places (4 at the front and 2 on the tender rear).
Were they all originally green or were they 4 green up front and 2 red on the tender?
Guess you can tell I've dedicated this day to AF issues
Thanks
