DC yard wiring

[gmpullman]

At a minimum you would need one "gap" or insulated joint on each piece of rail that bridges frog-to-frog AND all the electrical feeders must be from the point side of the turnout.

Basic rules of power-routing turnouts. Any frog-to-frog rail must be gapped, no matter how far apart they are and any feeders (unless switched by auxiliary contacts) must be at the point end of turnouts.

 This holds true for DC or DCC wiring.

My entire layout was originally built using Shinohara "old-style" power-routing turnouts. It was a learning experience.

Hope that helps, Ed

Thanks for the replies, but I am not really asking if I should have more than one block.  What I am asking is assuming my yard is all one block, then can all the track and ladder switches be connected with conductive connectors and each spur wired + and - as well as the ladder source wired + and -?  Is there any conflict electrically in what I have said?  Thanks, Jim

As Roger points out, it's easier to do now, the later.   Switches on ebay are dirt cheap.

I would recommend a couple of on/off switches on a couple of tracks. You never kinow when you will need to park one engine when running another. :-)

The switches are live frog older Shinohara and I don't intend to have but one locomotive on the yard at a time.

 What turnouts are you using? THat can make a difference in how you have to wire it, but in the end it can be all one block, if you have no desire to park a loco on one of the tracks.

If my entire yard is going to be one DC block, do I need insulating connectors between each spur and the ladder, or can I just wire each spur + and - and the ladder source + and - all connected as one block when attached to a block selector?  Thanks for any help on this.  Jim
