Can anyone point me in the direction of low cost volt amp and watt meters. I want to incorporate them into my control panel. Analog or digital is fine.

Am curious why you ask about watt meters? To be clear, I believe there are many benefits to a watt (power or scale Horsepower) indication but as others point out, this is not common practice and I don't think you will find any that are "low cost". It is technically difficult to accurately (within, say, 10%) measure Watts in a model train layout; there have been a few threads on OGR that get into the technical nitty-gritty if you care to dig deeper.
