I have a train set from probably over ten to twenty years ago and i can't find it anywhere on the internet. It's a Bachmann, Long Hauler, N Scale train set  with twin locomotives, 6 cars, tracks, and the power pack. I don't know how much it's worth or who to get in touch with to sell it. I was going to sell it on Ebay but don't know what it's worth. Can anyone help me out with this?
