W. W. Brown was built in 1902, lasted until 1964 as the Harry T. Ewig. The elevation print for her 1939 conversion to a crane ship is on the wall at Brennan's in Grand River OH. Long service life is common on the lakes. There are several 70 year old boats in active service, 2 recently scrapped at 80, and one from 1906 still working.

I was out on a similar steam powered dumper in the early 60's, before the liability crisis hit - "OK, be careful!" Strange to see a full size modern hopper car hanging upside down...

There's still one of these loaders that lifts the RR gondola car up by elevator to dump to the loader shute in Ohio, I can't recall which port, but there are several that push the gondolas up a hill and turn them over to load ships from a similar loader along the southern shore of lake Erie. The one at Toledo is quite busy.

This is really interesting. It's a type of "rotary" dumper. Well, not rotary, but you get the picture. Operation was rather interesting. Cars would be pushed onto the dumper, locked down, and then lifted up where the machine would slowly rotate to dump the car. In this case it looks to be a gondola car other than the usual hopper you would expect.
