Blocking and DCC
Posted by rcato on Friday, March 27, 2009 9:58 PM

Hello.  I'm going to build a table top layout, 9X9, u-shaped.  Most likely in stages (sectional). It will be in the garage.  All I have room for.

I want to use DCC, but I am a novice, running only one train on the layout, with operations/industries. 

 I may want to run more than one but it is only going to be me operating the railroad.

Do I need to wire it with blocking? 

Thanks,

-Ron

Hey Ron,

Blocking would be recommended if you want to prevent a problem in one portion of the layout from affecting another portion.  Also, to be effective the blocked sections would need to be supplied from designated circuit interuptors or power boosters.  Short answer - if it's just you, and one loco at a time - don't worry about blocking.

 Long answer - check out this website for good advice and learning.

I guess I should do some blocking for the learning and experience.  Thanks.

I got redirected.  Still learning the protocol.

I don't believe you need to block like analog DC systems. The beauty of DCC is that you CAN run more then one engine SEPERATE from one another without having a power issue. the speed,direction,etc is controlled by your system controller by addressing each engine.Now if you want to put power blocks in,thats fine, but you don't have to on a smaller layout..JMO..Tom

If you remotely think you want to down the road put signals on your layout, you have to have block detection. It also helps for troubleshooting. I would recommed that you block wire. I have been block wiring my new section for over a week. Its a pain, but worth it in the long run.

Of course if you're going to have a reverse loop you need to separate that as it's own block like you would in DC. Nice thing is you can use an automatic reverse unit so the track polarity is reversed as the train runs thru the reverse loop without you needing to throw a reversing switch.

Plus - not everyone agrees with this - but it's nice to have a section of track on the layout to use as a programming track. Ideally a stretch of single track with no turnouts etc. that you can isolate. That way, you can program speed, momentum etc. and then try it out and make more adjustments without having to carry the engine back and forth to a separate programming track.
