Hi Maury,

Look at all those valves!! Well done!  can't wait to see them at NAMES. 

John, The valve bank is designed to let the engine run on one, two or three cylinders depending on the dynamo load demand.  You can also choose which one or two of the three cylinders you want the engine to run on.  A very wide range of operation and steam efficiency for the time.  The dynamos are also designed so that one or both can be taken off like to further conserve steam during low demand periods. A unique piece of steam history.  It is also interesting to know that the Dickson co eventually merged with another manufacturer and became Allis-Chalmers who built some great large engines.  The dynamos were made by the Edison Co.  If you make it to NAMES, I will try to have some of the history written up and available there.

The power station in NY had seven of these monsters all lined up in a row.  We have some photos of the original installation at the power station.  This was the first time a large marine engine was direct coupled with dynamos.  The engine at Henry Ford Museum has dynamos stamped #3 and #4 so we believe it was the second engine set installed at the NY power station.
