Why go through all that trouble to produce steam when you can just stick a Democrat down there and let them blow hot air?
@SwiftOnSecurity Most big cities have one or more restoration projects. Restoration can be slow and expensive - beginning with removal of the asbestos jackets that were used around the boiler.
On ours we have had to replace the tires on the wheels (big steel tires which then have to be turned on a very large lathe make sure they all have the same circumference and "profile" shape.) We've had to make new leaf springs, new bronze bearings, new tubes, and new hollow stay bolts. Lots and lots of work.
Most of these restoration groups wouldn't mind more helping hands (or donations of $$.)
