One rotary handles the turntable spoke tracks and the second handles the adjacent freight yard. I patched the DCS-RC into this feed and gave it a try. Works perfectly.
By "this feed" do you mean just the freight yard. I must be misunderstanding but with an A-off-B toggle it seems you would need one DCSRC for the turntable feed and a second DCSRC for the freight yard feed?
...Normal operation is to select the yard or TT track I want, then power it up from either the A or B source.
Got it. Your diagram makes it perfectly clear. I misunderstood the purpose of the A-off-B toggle; I thought it selects (A) yard or (B) turntable...but it selects the TIU source from (A) Fixed 1 or (B) Fixed 2. So only 1 DCSRC needed.
