I recently added flat top 12v LED's to two of my diesel locos and they are great except for one thing, they flicker when the engine is in reverse. These LED's came with resistors already installed which was a time saver but now if I wanted to add a reverse protection diode it would be almost impossible to do without destroying the LED. While searching for the answer to this problem, I came across the following circuit on this list and am wondering if this will work to eliminate the reverse flickering?

I picked up at least 200 old ho tracks and switches at a garage sale. It looks pretty dirty and I’d like to clean it up. I know about isopropyl alcohol and q-tips. I don’t see any rust but they look like they’ve been used and then stuffed into a container. I’m new to model trains. I’m really enjoying the fact that we found my father in law’s old 0 gage post war Lionel set with track, switches and cars. I also had a full set of HO trains and track as well as a large assortment of N gage track, cars and switches. Any thoughts 

thanks

I have been thinking about how to positively lock turnout points to the stock rail without resorting to powered turnout throws (i.e. Tortoise and others) or commercially available manual throws (i.e. Caboose Hobbies).     I especially wanted to “lock” the points in place in my yard and industrial tracks that are within 24” of the layout fascia.   I prefer to use a skewer or finger to move the points.
