Don't you mind if I talk about the theme of this thread? ))) I think, the best power supply for any layout is the one for PC's. It has 12V, 5V, 3.3V, -5V, -12V, so you can easily make any voltage you need: 24V 17V 12V 10V 8.3V 5V and 3.3V
If you use only 12V for your layout you will have about 20A on it. It let you easily run about 5 to 10 trains at the same time. You just needs the switcher (controller) from an old railroad power supply or just buy one in radioshack or some shop like this =)
WTB any of the HP Products locomotive parts
