LGB R1 dead frog points.

Ah forgot to mention that issue as well. Even worse at times on R3 points.

Indeed.
From my experience with R3 points you may get away with a slight hesitation on analogue but on DCC it tends to trip the sensitive overcurrent detection in the central station thereby bringing everything to a halt!
 
I have a KoF 0-4-0 diesel with a 'stay alive' capacitor fitted to the Massoth decoder, which does help on points and any dirty track sections....
 
A problem I have identified with one on my R1 points is the moving point on the straight line dropped below the head of the rail, so as the loco ran along the rail (from the frog) the tread sat on this lower rail and when the wheel got to the end of the point the side of the wheel jammed on the main rail head - quite difficult to describe.
A small amount of plastic under the brass strip the supports the point rails and all is well, and filed away ready if this happens again.

Jimmy, if you have covered the brass strip with plastic strip, then this can insulate the rail from the power. Although power to the rail is also provided by the pivot screw, this can also become an electrical issue.

I would suggest you use a strip of brass, but you would need to solder this.

Though it might be best to lift the point and check both above and underneath for the cause of this problem....

The plastic is UNDER the brass strip the raise it, the point still slides on the brass.

Apologies Jimmy, I missed that bit!

I still reckon lifting and inspecting the point for any loose screws on the pivots would be in order though....

Had the point on the bench, and the brass strip that supports the point blade is just bent in place, and regardless of what i did (until the plastic strip) the blade when opening slid under the head of the rail.
 
Unusual problem Jimmy, although Chuggy seems to have had a similar issue with a USAT switch?

But you seem to have engineered a suitable fix....
