Darn spell check and hunt and poke keyboarding.



Let's try again



The throwing of all four turnouts is all very well electrically, but operationally can be a nuisance ,

With turnouts as large as #8 it is possible to have equipment sitting on one of the turnouts while a through train crosses the diamonds and will not physically foul the other. If the diamond's frogs ARE each completely isolated from each other and the adjacent turnout frogs, one only NEEDS a dual juicer as only two frogs to change polarity/phase. The upper and lower frogs (3&6 in the diagram) will always need to match either the A or B rails, whichever is appropriate.
