Conventional Block Wiring

[Anonymous]

I'm wiring my isolated blocks for conventional only operation. Was looking for input as to how many, and length of blocks to use. Seems that too many blocks can become unmanageable and too few not enough control. Also how long should they be at a minimum , I was thinking about the size of your expected longest consist. Any suggestion will be appreciated. Thanks, Ralph.[:)]

The answer depends a lot on what your layout looks like and the size. Care to elaborate?

The layout is one level the main table being 7'X13' off both ends are extensions app. 5'X4' with reversing loops, those extensions have track that loops back and across stairs and back down to connect into the other loop extension at the other end of layout. Sorry don't have pictures or now how to draw computerwise or otherwise for that matter. So total area is app 21X12' . I have a total of 15 switches which are remotes . All track and switches gargraves. I have on the control panel and wired to a terminal strip 10 DPDT switches for blocks which I operate from handle A or D on the modern ZW w/180W bricks. Hope this helps and thanks for the reply. Ralph.

My rules of thumb for blocking:

- A continuous loop which will run 2 trains in the same direction must have at least 4 blocks.

- each passing siding is its own block, as well as the parallel track

- each reverse loop is at least 1 separate block

- each spur on which you will want to store or operate an engine must be a separate block

To gain operational flexibility on a larger layout takes quite a few blocks. That is the big appeal of the command systems besides sound. They do away with the need for most blocks, associated wiring, and toggles. However, to get away from blocks, ALL your locos must be command equipped.

my opinions, your choices

Try to imagine all the maneuvers that you will want to make with multiple trains, while keeping each one in a separate block.

Put the gaps for a passing siding and the associated main track between the switches, so that a train can be stopped on either track while being passed by another.

Even with the command systems, multiple blocks are useful for isolating problems to a reasonably short stretch of track.
