Hi Bob and List members,
If you zoom in enough, under the last A in PENNSYLVANIA, you can make our the class markings - it is a PRR class F23 flat, series 435445-435450 (6 cars).
The road number can be found over the left-most truck, but it is difficult to read, apparently both faded and dirty, it might read 4354X0, with the X obscured by the wire rope, in which case this is car 435450, but I would not bet a whole lot of money on that last part.

A photo from the Maine Memory Network:

“S.D. Warren Paper Co. of Westbrook, Maine used this soda digester or sulphite digester fabricated at the Portland Company, which fabricated machines from steel and is one of the longest continually running factories in New England. This machine combines sulphite with the wood pulp to soften the pulp enough to create paper fiber.”

Notice the stakes placed to keep the cradles from shifting laterally and the steel(?) rods securing the load.
