You'll probably get varying responses and the CW-80 sometimes gets a lot of knocks but, IMHO, it should be sufficient.
I run about 110' of Fastrack with two main lines; a small staging yard, Legacy, and 4 command control switches with a CW-80. Running two Legacy engines and a Lionchief NJ Central with lighted passenger cars and partially upgrade and over 20 lighted and/or operating accessories (Gateman, Miller rotating signs, Lionel playground, etc.) and have no power issues.
If it doesn't work , you'll know about it soon enough.
