How To Wire A Double Slip
Jan asks readers:
“How do I wire a Peco SL-E 190 double slip? I have wired each point motor shifting the polarity of the crossing point most close to it. The slip works beautifully as a normal diamond crossing. But, if I activate the second point motor in the travelling direction in order to go to a siding a short circuit occurs when the locomotive reaches the second crossing point due to incorrect polarity. Of course the same problem happens when entering from the opposite direction.”

Hi,
Think of the double slip as two normal points superimposed on top of each other, back to back. Then you’ll see that the frog FURTHEST from the point mechanism should be switched, not the nearest.

Go to the web site below and find out how to wire all of Peco ‘Insulfrog’ and ‘Electrofrog’ switches including slips & crossings. The E on SL-E190 designates an ‘Electrofrog’ machine.
