MORE COMPLICATED POINTS

Now that we’ve covered ways of getting power to the frog while sorting its polarity – and where to add insulating rail joiners – we can apply this theory to more complicated points. We’re studying four here: Peco’s SL-E199 Electrofrog asymmetrical three-way point, an SL-E190 double slip, an SL-E194 Long Diamond Crossing and a scissors crossover made from short radius points and small diamond crossing.
