Just like some advice I have  just fitted  some servos to operate  some of my points with great success  but would like to try  dcc operations  but not sure what decoder to fit.
Any  ideas  ?

There are two possible approaches, and it will depend on if you already have some form of control board for them and how it is switched which is most appropriate.

There are several DCC Servo Control Boards available, quite a few have DCC decoders built into their Servo Boards.  Some like Peco have separate Decoder Boards, as Peco have sockets which can operate their Servos by simple on/off switches.  All that is required is to connect the Servo Control Board[s] up to the 2 DCC Bus wires and set the Servo Accessory addresses using the manufacturer's instructions. 

In the picture below the Peco Servo board is lower right and there are 2 out of the 4 possible servos only, as I was just testing the system.  The separate Decoder Board is upper right and connected to the Servo Control Board by the 5 wires and to the Bus Wires, by the two wires on the opposite side of the Board.  The 5 wires are a single return [Yellow] and 4 switch wires, one for each of the 4 Servos [Red].  It's all very simple indeed.

The 2 Blue boards are DCC Concepts Alpha Encoder and their Alpha Mimic.  As it is here, the Peco Servo Control Board will operate the points either by selecting the Servo Address on the NCE DCC controller, or the appropriate switch attached to the DCC Concepts Alpha Encoder and away it goes.   These DCC Concepts units are completely plug and play, which is soo simple to do.  One SPDT "sprung centre off" switch for each Servo [or any other accessory you may wish].  The 3 wires from the first switch are plugged into the left hand Blue Board at the upper left. The others will simply connect up the same way to each of the 11 other switch input sockets.  The Mimic lights change colour appropriately and there are 2 for each Servo [left route or right] which plug-in to the labelled sockets round the smaller blue board, they can be seen shining out around the table.  The input for all those lights is a pair of wires connected to the Bus Wires and can be seen at the top of the smaller of the blue boards.

The other small Board, with the blue/white ribbon, which is sporting a lit "h" or "4", depending on which way up you look at it, is the Setting-up Board for the Servo control [Angle Sweep, Speed etc] and would normally be disconnected for running the layout.

The second picture is where the switches and lights will fit on the Mimic Panel and Points Control Board.

The underside of the box, waiting to fit the boards inside and connect everything.  I am really pleased with the system, using DCC control, because my layout is on 5 separate boards and running control wires from DC switches to 10 Servos would be a massive wiring loom, with at least 10 connections to plug in at the ends of each of the boards.  Because of DCC and the Alpha Boards, I only need 2 sockets for the 2 Bus Wires.  A big thank you to Richard too who pointed out just how simple it could be.

Others will have slightly different Servo Boards, but will be similar in essence.  I hope this might have given you an idea of the sort of thing you might look for.  If you Google "OO Servo Control Boards" or "Model railway Servo Control Boards" there are quite a number and variety out there, for you to pick what might suit you and your layout.  It's a good idea to have a calculator nearby, as prices for them can vary quite a lot.  There is also a variety in the numbers of Servos that different boards will control - calculator a good idea here too.

Regards and good hunting.
