Huge 1950s Lot HO Train Collection Unboxing - Will Any Work?

I was browsing eBay one night and I found a listing for what looked to be two locomotives however after having a closer look I realized it was actually an entire collection. I suspect this set was put together sometime in the 1950s or possibly early 60s.
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 four to start. One of which was able to pull some of the cars included in the lot.
