I use N scale Peco electrofrog turnouts, the points are notoriously poor for electrical contact to the stock rails once dirt sets in and need an auxiliary set of linked contacts to power the frog reliably, such as a microswitch or turnout motor contacts under the table.
In the LHS the other day I was looking at some Peco HO scale electrofrog turnouts and noticed there were additional contacts mounted on the underside of the points that slide under the stock rails. These contacts are not present on the N scale turnouts.
Can anyone comment on how well these HO contacts work? Does the frog need additional contacts for power switching or are the built-in contacts reliable enough even when they accumulate dirt?
The original N electrofrog turnouts used to have these extra contacts, circa early 70s. Try a thin coat of Peco Electrolube on the inner surface of the rails where they contact each other, this seems to keep good electrical contact over a long period of time!
