Get the Prodigy Advance "Squared". It has three amps of available power. It'll run just about anything. I have a lot of lighted passenger cars that have BULBS instead of LEDs. A standard, basic 1-2 amp DCC system just trips the breakers, and just running one train with seven or eight lighted coaches. I invested in the Prodigy Advance, and can run multiple trains with lights, without issue. If you need a 3-3.5 amp system, it's the cheapest way to go...
