Huge 50 Year Old HO Train Collection Unboxing - Will Any Work?

I was browsing eBay one and found a listing for what looked to be a huge lot of locomotives and I realized it contained both HO scale and N scale engines. Most of the locomotives are not in working order as they likely have been sitting for many decades however I was able to get around three to start. Two of which was able to pull some cars.
