Description
A PECO HO / OO (1:87 / 1:76) Code 75 double slip with Electrofrog. A double slip is two turnouts and a diamond crossing combined into one unit — it lets traffic pass straight through, or diverge to either side, all in the footprint of a single crossing. Standard at the throat of busy stations.
Electrofrog: the entire frog is live nickel-silver. There's no dead-spot, so short-wheelbase locomotives crawl across it without hesitation. The tradeoff is wiring — for DCC, isolate both diverging-route rails just past the frog (use PECO insulated joiners), and switch the frog polarity from the point motor or a frog-juicer.

Wiring & DCC
Slip crossings and scissor crossings have multiple frogs that all need polarity switching. Plan for two SPDT contacts (or two frog-juicers) — see PECO's Wiring the Layout No. 21 booklet for the wiring diagram.
