My (unsponsored) testimonial for Stout Auctions ...
They sold my Rock Island oriented collection of trains plus accessories and control gear in one weekend -- eight pages of inventory listings. They picked up the items, took pictures, grouped items together, and posted it all on their website. I received a check promptly thereafter. Their service was convenient, efficient, and honest.
A cautionary note - you'll likely receive about one-third of the value you believe your trains are worth. Some top-rated trains will attract bidders willing to pay a top price. However, it is inherent in the auction sale environment that potential bidders tend to be bargain hunters seeking a really good deal. That is what it is, so adjust your expectations accordingly.
Carry on, regardless ...
