If you have never used DCC before read this first paragraph. Im going to try and explain in simple terms how dcc works.

Right, here i go. Lets start with DC, with DC when you turn the control knob of your layout, it powers the track and moves your locomotive. So if you had 10 locos on the track they would all try and move at once. (unless they are isolated in sidings or via switches). Hope you follow so far.

With DCC the track is all LIVE everywhere on the layout, you do this by basically running wires to every bit of your layout from the controller. This is often reffered to as a bus wire, its so the power stays strong all over. Now with DCC every single loco has got a Decoder in it (chip) the trains all sit on the live track. You give every single train its own idividual number, this is done on your own idividual controller , depending on what brand you go for. Now with dcc unlike dc, you can select which train you want to run by telling the controller the number of the train. So the controller then sends the digital signal down the live rails up into the loco chip and tells the chip to move that train. So the chip "says go" and takes what power it needs from the track and sends it to the motor and moves the train. All other more complicated functions and dcc items also get there power from the track , like lights and sound.

Does that make sense?? Hope so. Let me know.

Below is a list of the gadgets and equipment i use to run camelot junction.

Lenz set 01 (bit old now but has the latest chips inside, so runs like newer set100). + Transformer

Lenz handsets LH100, LH90, LH30 .

Lenz LS150 point modules x 5.

Lenz BM3 modules, for the signals. 8 at the mo, more still needed.

Lenz BM2 modules, also for signals.

Lenz Interface for pc control

The pc program i use is by http://www.friewald.com and is Railroad and co version 5.5

All the locos on the layout are chipped with Lenz gold and silver chips.

There are various other Lenz gagets and stuff in my parts draw, that still need adding........ no time

Here is my Lenz SET 01 , this is the main brains of the system. With an adapter plate on the right for attaching controllers anywhere on the layout, there are 3 of these around the layout.

This is my computer interface, it basically plugs into the pc and the back of the lenz box. This used with railroad and co software will allow me to run the entire layout from my pc.

This is my LH90 controller, this also plugs into the back of the lenz to allow another operator if needed.

This is the LH30 controller, it lives over by the yard and i use it mainly for shunting. (think it needs a clean)

Here are some signal modules by Lenz, two BM3s  and one BM2 these control the trains stopping and starting at signals. I will add some diagrams soon. Here is the basic priciples of the wiring , that are in the manual. http://www.lenz.com/manuals/modules/bm3.pdf

Here is one of the lenz LS150s that control the point motors on the layout. 6 points to each , this one is under the main junction by the 2 tunnels.  You can see points in slots numbered 1-5 but not six. This works the same way as loco chips, you just give the points their own number like you do with locos, and just tell them to move left and right and the LS150 does the work for you. Bottom right of the LS150 you can see (JK) this is the input from the back of the controller(bus wire) this is where the ls150 gets its commands.  Bottom left is the power supply to the unit i use a separate 18v power pack for the points.

Below is a very basic dcc wiring diagram with a few bits on, i will add more when i think of them.
