Friends,
Is a double slip some form of compact point?

I was reading an article where it stated that a Double slip could be utilised but no explanation as to it what it is and its function.

Regards, Peter.

Double slip:  An article of female attire worn under a dress?

Essentially a diamond crossing with two points combined.  Very compact.

A nice complex bit of trackwork and only relatively new in Peco Code 55. You can get a single slip as well. As NinOz says, a train can traverse another track just as it would on a diamond crossing, but if needs be can also leave it as it would a standard point into a siding say, or another platform. Such trackwork is very common in large station throats.

Yep, that's the one! Thanks for providing the pic!

With most of my aging layout being Code 80, I haven't got any of these. However I have acquired a Peco scissors and the final stage of my layout (a very large station) will be Code 55.

I would be interested to hear of the reliability of these Peco slips. Good, medium, poor?

Cheers 

I have a single slip on mine, been fine so far

Also got TWO scissor crossings but sadly they're in the fiddle yard where no-one but me can see and appreciate them! :'(

Yeah... I'm gonna make sure mine will be visible - if only because of the price I paid for it (A$139.50 in Adelaide!!)

More  :'(

Peter,
I have two and both work fine (over 10 years old).  Each powered by 2 Peco motors with 2 micro switches to change frog polarity.
For usage double slip: can enter from 4 directions and can select either of the 2 opposite exit routes, ie straight across the diamond or slip off to the side.

For a single slip : can enter from 4 directions and can select either of the 2 opposite exit routes for 2 directions or diagonal only for the other 2, ie straight across the diamond or slip off to the side for one side of slip only.

Cool diagrams. I was going to show you that, Peter but am not computer savvy enough.

My excuse for using that smiley! 

Thanks for the post, NinOz!

It is true a picture speaks a thousand words!

Just what I was hoping for a simple diagram to explain the basics, many thanks!

Regards, Peter.

The station that Cant Cove is modelled on (although the geographical location has been changed, a branch added plus a siding with a single-road engine shed) once had a double-slip but it was removed in the 1950s (probably to save money as they were expensive to maintain). Although I do have a Peco Code 55 Double Slip, SL-E390F, I finally decided not to use it for Cant Cove as not having it makes for more interesting shunting (the main operating interest of the board) as, without the double-slip, there is no direct access from the mainline to the station yard and the branch. It also saves me the complications of dealing with double slips (point motors, wiring)!

The set up just out side Gillingham station when the engine sheds were there. You can see the double slip.

Sorry about the quality, its the only pic I have

To make things a bit more complicated after this good explanation: you have inside and outside slips. The models shown here are inside slips.

Marklin for instance has outside double slips (also called Bäseler kreuz)

Oh, I never knew there were two types of double-slips!

If you fancy having a shot at some of the peco ones on your layout Peter, then fear not.  I have 2 on mine, and they seem to work fine - I've got them installed to be operated manually (as in, i just lean over and push the lever) and I've got surface mounted switches wired in to swap the polarity around.  They help greatly to smooth out curves in yards or station aproaches as they are so much shorter than the operating equivalent of two points set back to back.
One day I will do some scenic stuff and get the switches hidden!
