My vote would have been for a milk car and platform, but you already have that. I also have many other vintage PW operating (I use that term loosely!) accessories, so the only advice I will provide is that if you want something "almost foolproof" you should consider some of the modern reissues of the original. I am not interested in paying high costs for the TMCC operated versions, but I have replaced the bascule bridge and 164 lumber loader with button-controlled reissues and they run far better with little/no tinkering. Finally got tired of replacing worn parts. Also reasonably priced.
Whatever you decide, enjoy it!
