I have a task that I'm set on. I would like to add real water features to my model railroad. Problem is, I don't see anyone else doing it. There's all this lookalike water stuff but it doesn't look like the real thing, it's close but I would love to have my engines run along the backside of a waterfall. So if anyone has any ideas or any sites I can visit to do so, please let me know. Is there anyway to hear the sound of rushing water with little electric engines? Thanks guys.
