WhyDividemyLayout?(Courtesy of Kalmbach Publications)
Though Command Control offers a more realistic type of train control being able to run multiple locomotives independently on the
same track the electricity running through the rails of your lay out still needs to be properly managed and distributed. Since one of
the big selling points of Command Control is that you don’t need to divide your layout into individual electrical blocks for independent
train control, you’re probably asking yourself, “why should I do it?” In addition to minimizing operating disruptions, power districts are
also a key to AC power regulation. If you’re running a lot of trains, you’ll need to make sure your AC system can supply all your
power needs efficiently and safely. Adding power districts to your layout by using Circuit Breakers can help with that. By separating
your layout into districts, you divide the total track power available into smaller, more manageable units.
How do I Determine Power Districts?
There are really two types of power districts: those that are circuit breaker protected zones on the layout and those that have their
own independent AC Power (also breaker protected). Probably the best way to determine where to place power districts is to take a
look at the expected current draw, (Traffic), for each operating location on the layout. For example, a busy yard might have two
switchers, one or more trains on the arrival and departure tracks, another train or two passing the yard on the main, and maybe a
peddler working nearby local i ndustries. If some or all of these trains have more than one locomotive, you could have 10 to 15
current-drawing units all competing for power in a fairly small area. Even assuming that the locomotives have efficient motors, this
type of load may be heavy enough to slow down a AC system running on a common AC System. Generally, our experience has
shown that in “O” if you have for a 12-14 awg buss and 18 awg feeders, that a 5 Amp system can support up to 5 0perators. Many
users overestimate the amount of power needed. Try using the PSX Series first, then if your trains start to slow down you may need
to add extra AC Power to support the concentration of trains in this location. By dividing a layout into power districts in this manner,
and using a combination of AC Power Units and/or circuit breakers, you can make the most efficient use of available power on any
mid-size or large-size layout.
