Steam & Excursion > Whazzit? (43)

Been awhile since I've done one of these Whazzits, so here goes.

Anyone recognize it?

LOL.  And, I'll admit not a very good one.  I don't know how to do fillets gracefully.

It looks like boiler and firebox. Were you trying to do a wagon-top boiler? If so, that would not be correct.

You're correct, it is not a representation of a wagon top boiler. You're also right that it is a boiler.

What type? Which engine(s) used it? What RR or RR's?. When? (The question I don't have the answer for is why anyone would do this). (But, it was done - big time.)

A very early locomotive boiler deisgn, English, Maybe 1830's
Before Stephenson's "Rocket", and later designs

Stilts

Nope - decades later. And, AFAIK it's only in US.

Whazzit a Wootten Firebox?

Cheers, Dave

No, sorry. Thanks for playing.

Articulated loco...perhaps a cabforward or a challenger

Umm..... Nope

It's not an oil burner, either.

A Blivit.

Something on the D&H?

It does look odd enough to be something D&H might have tried, doesn't it?

But, no, not used on D&H to my knowledge. It was, incidentally, a single pressure boiler.

Here it is from another angle.  Keep in mind that I didn't draw fillets where surfaces join.

Nobody's come close, yet.  Here's some clues.  Locomotive designers and builders have almost always felt it is important to have steam space above the firebox, where the most heat is generated, but there were three notable exeptions.

In the 1850's the Millholland boiler and the boilers on Ross Winans "Camels" were built with a sloping, though semi-circular in cross section, roof sheet over their firebox, as shown in this illustration from Bruce's "The Steam Locomotive In America".  Strangely, Bruce neglects to mention the boilers that are the subject of this posting.  Very large numbers of these were used for two decades on three classes of locomotive built in the late 1870's by a single major railroad!

Strangely, one of these locomotives found it's way to Minnesota, to serve on two logging railroads here before being sold to another logging railroad in upper Michigan.  It operated on a portion of the very trackage now operated by our North Shore Scenic Railroad!

What was that original railroad, and what was the boiler design named?

Hint: It was the first standard boiler on the Standard Railroad of the World.

Well... at least you don't have to worry about designing backhead braces.
