I have just constructed a large double loop of fast track with one set of switches that can have the trains interchange loops. Imdont think enough power is getting to the track. There are three sets of wires coming from the transformer to the track at different locations. Is it the transformer not powerful enough?????

I had no problems with CW-80 on my first Legacy layout (20 X 10 inner and outer loops, with a climbing loop and trestle) I ran two freight trains, both double engine consists, 10 cars on each. Sometimes a single engine passenger train instead of one of the freights. Half dozen fastrack remote switches. One connection to track with the short wires (probably 18 gauge) supplied with the Lionel terminal section kit. I ran mostly at speed step 80 and below, never past 110 step. Nothing tripped or got warm.
As you add more track, loops, engines, accessories, etc., I recommend getting a ZW. Then you can have 4 power blocks and keep your engines unpowered that are not being used.
A 180w brick would be plenty,you can then use your cw-80 to power any accessories, thats what I did. In fact I have 2 cw-80s that came with sets I purchased early on. I now wire my accessories to the throttle side of each and this allows me to adjust for the recommended accessory voltage, usually 12-14 volts. A cw-80s overall lower voltage is more accessory friendly.

If you have the modern ZW with four outputs that is all you need. (I assume you have at least two 180 watt bricks attached to the ZW.) Use three of the outputs for the three loops and you have an extra one left for accessories or a fourth loop. Hook the Legacy wire to the ZW common.
You can still run conventional since the ZW voltage can be independently controlled on each loop.
