Yes to your question.
But allow me to elaborate. Some layouts with a roundtables, plus a yards, plus multiple sidings, etc. are so large that when you draw out the wiring diagram with multi-position rotary-power switches, multiple AIU ACC(essory) ports, or whatever block/section powering method you chose...it turns out that the wiring is simplified by using 2 or more PBW's. If you bide your time, you can pick up a DCSRC for next to nothing on ebay or thru the buy-sell OGR forum.
