Good day, how do you get the engine to go faster, it will not go any faster. It is at very slow speed. The other question is can you hook up 2 44910 together, and should you? can you also hook up lights to the power unit and how many mA are there at what volts. I need 12 volt out put for lights. thank you for your time P.S. I LOVE YOUR ITEMS!!!!! I am a disabled Vet and am doing a train layout for therapy, I only use your items. You have the best on the market. I want to thank you guys for what you do for people, that is sell a good item that is outstanding! Steven from Kentucky
