Your Guide to the Peco Unifrog Track Range

Unifrog is essentially an evolution and combination of the previous “Insulfrog” and “Electrofrog” formats. Each Unifrog point is supplied as “Insulfrog” as standard, with the option to wire them as “Electrofrogs” instead – providing you with the option to upgrade your layout in the future.

The “frog” is the part of the point where the tracks diverge. Insulfrog points feature a long plastic isolated section here to stop a short circuit from occurring when a powered locomotive runs over the point and bridges the two tracks. Electrofrog points had a much smaller isolating section.

Unifrog points feature a much smaller isolating section, more akin to Electrofrog points. The difference here is that your wiring can be modified to suit either Insulfrog or Electrofrog formats – with the option to change this later should you wish, without having to remove the entire point.
