I run my HO trains Using Kato track. I have no problems with the signal on the main line but in my yards when starting them up the signal is non-exsistant. Once I move the loco to the main line it acts as it should.
The switches going into the yard are number 4 and they are power routing. Is there a way to fix this so the signal goes all the way into the yard Besides powering all the yard tracks?
To repeat what David said......... DCC is finicky and needs constant and steady signals fed to it to work properly. What this often comes down to is having power feeders attached every 4 feet (some say 3, some say 5 or 6), plus all sidings and dead end tracks no matter how long they are.

The "problem" is the power routing turnout. What type of turnout is it?
Peco? If so, Insulfrog or Electrofrog?

This behaviour could be due to a number of issues. One could be joiners linking unstable track elements, or dirty joints maybe with corrosion. It could be, as Rich says, due to the engineered qualities of your particular turnouts if they are power-routing. If the turnouts aren't lined to the siding or ladder track in question, and that length of track has no direct feed, the track will be dead if all that connects it to power is a pair of joiners at the frog and stock rails of the turnout.
Maybe metal tab wipers are worn or dirty if the turnout is meant to route power via that means.
Thanks guys for the tips, looks like I will have to add feeders to each yard track.
Let us know if you get it all working.
If those turnouts are Peco Electrofrogs, you will be faced with some additional issues.

Here is a nice little primer on Kato turnouts.

The power routing feature likely is what is resulting in an absence of power to the yard tracks.

You're missing a benefit of DCC if you are using power routing turnouts.
For a loco to run it has to have power. You're power routing turnouts have either diverted power AWAY from that loco, or it's contacts are introducing noise into the signal. I had a similar problem in the yard when I was converting the clubs power routed DC layout to DCC.
Gap each inner rail of the switch and power every yard track is your best solution. It's not the only solution, but it's the best.

DigitalGriffin...Gap each inner rail of the switch...
If Kato's HO scale power routing swicthes are like their N scale ones, then it is not necessary to gap the inner rails.
I did some test wiring on one yard and everything seems to work just fine.
thanks guys for all your help.

There's more than one way to power route, and over the years different brands of turnouts have used different ways. Some, like Peco Electrofrogs, set the whole frog and the diverging rails beyond the frog to the same polarity as one or the other stock rails, depending on the direction of the points. These types require gaps on the diverging frog rails between these rails and any downstream feeders, or else you get a short. The other way is the way Kato does it, the non-selected route is dead rather than at the same polarity as the selected route, so downstream of the turnout you have the stock rail side still connected as normal, and the other rail just open circuit, not connected to anything. These don;t need insulating gaps on the diverging rails and you can freely add feeders to defeat the power routing.
I remember seeing these two different types illustrated in the wiring section of one of the old books I have. I can't remember which brand did it the way Kato does, maybe Tru Scale. It requires more internal wiring in the turnout, the more common way is like a Peco Electrofrog which is also what you get building a turnout per the Fast Tracks method (though they are not power routing as built - they just need gaps in the diverging rails).

Having been op DCC 20 yrs I learn't very early, best practice is power feeders to every piece of track on layout including turnouts. A lot of extra work but saves much frustration in the long run and also stops any voltage drop.
Rout power to frog if you want (I don't as I use insulfrog with no problems) but power rout to tracks is not neccessary with DCC.
