A 9v. battery might be able to light the bulb in a loco, and maybe make the loco crawl a few inches. If you're looking to test locos, your best bet would be to find a cheap power pack, like the ones in toy train sets.....And get the connector track as well so you don't have to "fiddle" with the wiring.
