I finally got fed up trying to run trains at low speeds over the Peco scissors turnout and decided to replace it with a Kato unit. During the dismantling of the Peco unit I found one of the wires to one of the Dual Frog Juicers was broken. This was almost certainly the reason why Locos would not cross the Peco scissors at slow speeds without stalling. However I decided to continue with the swap as I saved 4 point motors and 2 dual frog juicers for future use. The Kato unit is a single point motor which throws the rails to either straight through, or crossed. How simple!
I did a few more jobs before Perth’s 40 degree plus Christmas drove me indoors! . . .
