He is only adding a second power track, so no need to isolate. A second power pack should be isolated, but would not increase any voltage.

... I was curious if I could use a second fastrack power track with the power pack it comes with to increase the power on my layout?

Make sure to isolate the track between the two power blocks. Fastrack has two pieces, 1 3/8” and 5” isolated block, that will separate the center rails. You don’t want to apply too much voltage to the track and damage your engines.

He will be adding power(watts), not voltage, in this parallel scheme. No need to isolate for these power levels.

I'd recommend placing the power feeds at opposite ends of the layout.  T

Mitch is right - place each pack at distance on the layout to enhance power distribution.

Rob, could you pls post a schematic ...

Well, there really isn't anything fancy about parallel LionChief power supplies, but here is a pictorial. The wall wart diagram is simplified for clarity and doesn't show any circuit protection, regulation, or filtering.  This shows three terminal sections, which should be distributed evenly over larger layouts(could even be in different rooms for a large carpet layout wandering through the house).  Once one trips due to a nearby short, the others will soon follow in most cases until the short is cleared.

Rob, Thank you very much for the clarification.  For whatever reason, the discussion wasn't making sense and thus the request for the schematic. 

Rob and Mitch,

Thanks for the insight. I had never realized that.



So does this (far fetched) scenario work the same?

Large, single loop layout

Flat - no grades

Planned to break it up into multiple blocks to ensure adequate power if I were to run multiple trains following each other around the loop.

Trains will all be weighted to run at the same speed so none will overtake the other.

AC xformers for power but won't be adjusted. Just switched on or off via. a switch.



In this scenario would I not need to incorporate those block breaks and could just connect multiple AC xformers if they were all set at the same voltage?

How does the phasing come into play beyond the blades of the plugs being aligned the same way?

Thanks,
