Hi All,
Curious about the differences between a single or double slip. I have had a look in the latest Peco catalogue and both look very similar with a few subtle changes of the check rails.
Could someone please explain to me in easy to understand terms the difference between the two.
Thanks, in anticipation,
Eddie.
Have a look at:

Double slip allows you to de-rail stock that enters the slip from any of the four available directions, a single slip will only derail stock entering from two. :-)
Seriously, a slip is like a turn-out/points whatever you want to call them mixed up with a crossing. A double slip will allow traffic to enter the slip from any one of four directions and leave via either of the two opposite ones. A sigle slip is like the above but for one direction it will only let you go straight ahead (like a crossing) but from another direction will let you take either of the two opposite exits (like a turn out).
In the main single slips used on the full sized railway to give a bit of flexibility for traffic entering/leaving yards and the like whilst still preventing "wrong line" running. Double slips being used as a space-saver in yards where there is les chance of making stock run the wrong way on a running line ... subject no doubt to lots of corrections and "ifs and buts" from the folks who really know.
Looking at a single slip, it will have a diamond crossing (two tracks crossing at an acute angle) with a single curved section across the obtuse angle joining two of the crossing tracks on one side or the other (left or right hand single slip). A double slip has the diamond crossing, but with curved tracks on both sides of the obtuse angles. All have the appropriate collection of point blades, guard rails etc. Regards, Bill.
