Wiring multiple blocks in two power districts
I
n the example below, two separate Track Power transformers are used, creating two separate
"power districts." In this case, Sidings 1-4 are part of one power district and two Main tracks
are part of the other. This arrangement can split the current draw of all operating locomotives
between two transformers, depending on which section of your layout each locomotive is
currently in. In this example, if the BPC2 had a TMCC ID/base address of 10, Main 1 and
Main 2 would be addressed via ID 10 and 11. The Sidings would be addressed via IDs 15-18.
