Here's a couple of useful power supplies. They work on US line voltage or from
100V AC up to 240V AC.
For unmodified train controllers:

You should get close to the maximum amount out of you controller, but the
controller well overheat if run with a heavy load for a long time. This may
requier drilling the center of the output connector with a 3/32 2.5mm drillbit,
not sure. I'll check when I get home.
Or for a modified controller:

This is what I use, although I purchase them locally at a slightly higher price,
but no shipping. And it fits the socket on the LEGO controller.
