It's also quite possible to build a module with more current output, I just didn't do that.
You could put a AC-DC buck converter in one car, set it's voltage to say 6 volts, and then use a resistor in each car to set the brightness. If you want more bulk capacitance, you add it to the filter caps on the buck converter module.
Thank you once again for your help with this. 
I love the idea of a converter. I posted and then went to make lunch. I started to think maybe it would make more sense to just put a rechargeable battery in the Baggage Car. I gotta say it is amazing how little power LED lights draw. The converter is even better though. Now I can take all the rollers off all the cars.
