I am in the process of building a 35 by 27 layout with 3 mains with 2.3% grades and 3 yards. I am thinking I would have 3 power districts for the mains and thus the need for 9 transformer terminations to address 9 tracks. I also have 3 yards and need power for lights, accessories and switch/signal. So I am estimating that I need at least 12 terminations and could possibly use toggle switches to power the yards off one of the mains when they are in operation. So two questions.
I have 3 of the ZWs with 180 bricks. I understand I can only address 9 outputs with the brick approach. I am thinking of then also adding a ZW-L. Can I mix the two ZW types with TMCC and Legacy and DCS and say have track 1 be a brick on a 400 and then tracks 2-9 using the bricks on two ZWs and then add the zw-L and have that be track 10-13? Please LMK if that would work in regard to TMCC and legacy addressing as well as MTH DCS when I add it.
Second question is what toggle switch rating do I need for the yard power switch to activate and deactivate a yard. I know its 20 volts but what amp rating would I also need. Any sources u know are great would also be appreciated as well as comments on my overall logic given I own the bricks, 400, and all the ZWs except the ZW-L. Also any input on best price for a ZW-L at york or online would be appreciated.
Thanks much,
