It’s pretty easy to build up a customized block system using several different types of switches.  The Atlas switches that Randy suggested are super simple and are a great way for newbie’s to go with.
 
I do like Dave Murray’s way using the turnouts for power switching in a yard, super simple!
 
My layout was built back in the days before DCC and it is totally set up for DC block control using DPDT center off toggle switches.  When I converted to dual mode DC or DCC operation I kept everything status quo and I can use either DC or DCC to power my layout.
 
 
This is a picture of my control panel using mini DPDT toggles.
 
 
My control panel is simple enough for my five year old great grand daughter to operate.  The direction of the toggle is the direction of travel in DC mode.

To the orginal question:

I used power routing PECO turnouts.  Feed the power from the approach track ONLY and when you route the rails to a siding, you also route the power to that track only.

Simple to wire, simple to operate.  Like me.

You have to look at problems like this from the interlocking tower.

The track alignment controls what power goes to which track. If you are using twin-coil switch nmachines this is problematic. If you are using Tortoise switch machines the project is dead simple.

A properly designed  interlocking tower controls the home signals as well as the turnouts. The track is powered when you clear the signal. (Home Signals are normally RED untill cleared).

Here is Interlocking Plaant of LION

And here is a local contact board controlling two main lines and four terminal tracks (sidings to you freight operators):

Nails are used as binding posts since I cannot afford barrier strips, nor can the LION manage screw drivers. A Soldering Iron is much easier.

A Tortise switch machine has two terminals for the coil and six represnting a DPDT switch. You can see these locations marked on the board. There are also six tracks represented: Uptown, Downtown, Tk3, Tk4, Tk5, and Tk6.

Since on layout of LION the left rail is GROUND, only the Right rail need be switched to control the tracks.

With these wired to the board it is a simple matter (so says the LION) to wire in the logic for this plant. The colored wires come from the switch machines, the black wires ciontrol the logic. You can see that one side of the coils are bonded to ground.

 

This sure beats going under the table to do the wiring and soldering.

BigDaddy
It can be done with a 6 pole rotary switch

.

I would suggest a 2 pole 6 position rotary switch. I think that is what you meant.

.

A single pole 6 position switch will also work, but I prefer to isolate both rails.

 But they have served well for beginners since Atlas released them and included full wiring diagrams in their track plan books.

That control box!  I was having a Homer Simpson moment over that.  They do the job but they are ugly. IMHO

 Atlas has the control boxes with switches. None of them have 6 switches but you just gang them together to get more. The Connector is the one you want, with just one power pack. Each one has 3 on/off switches., so you need two of them.

Welcome to the forum.  Your intial posts are moderated.

You are creating 6 blocks.  It can be done with a 6 pole rotary switch or 6 toggle switches, ebay will be the cheapest, but if it's coming from China it will be 3 or 4 weeks.

You can't independantly and simultaneously control different tracks with different amounts of throttle using DC and a single throttle.

Controling multiple tracks from 1 DC transformer
Posted by RQBD on Friday, August 16, 2019 1:30 PM

I am adding a 6 track classification yard to my platform and would like to independently control each track from a single DC transformer. I have the plastic rail connectors to isolate each track and can wire each track to a control box and then to the transformer. Who sells that type of control box to control multiple tracks?
