Thanks for your reply but see this thread:http://cs.trains.com/ctt/f/95/t/199136.aspx
The problem is the AC's will run on DC, but because of the weight, very slowly if at all.
Take a look at the MRC website under the Train Controls AC Power and DC Power sections. I do not know of any power pack that would run both DC and AC locomotives

I would appreciate suggestions for DC powerpacks capable of driving American flyer DC and AC cast engines with some indication of their quality and effectiveness.
Thanks.
