Steam & Excursion > BB: DM&!R 2-8-8-2 #210 (1955)

Oct. 8, 1955 was when Bruce Black took this shot @ Proctor, MN. 2-8-8-2 #210 was originally DM&N #210 built in 1917. Corrected date, see LarryDoyle post below.

Like them WhiteWalls😃

Seems like a small grate area for the engine....
A design element from an earlier era...(?)..

Later 2-8-8-2 locos had larger grates.... possibly for more steaming capacity .... needed when
running in “simple” for extended periods.

Built in 1917 as a Mallet Compound, the 210 was rebuilt as a simple engine in 1930, and since she outperformed every other engine on the railroad earned the nickname "Madame Queen".  She could pull 180 car ore trains!  Kept up to date with every conceivable appliance she served until 1957.

Thanks for posting this "big" steam photo.
#210 certainly has a rugged and powerful appearance for pulling heavy loads at slow speed.
However, the tender looks disproportionately small for servicing such a large locomotive.  Any reason?

As a matter fact, yes.  Prior to building this M2 class of engines DM&IR predecessor DM&N purchased 8 nearly identical class M1 2-8-8-2's with Baldwin Separable boilers.  A huge firebox was not required on this type of boiler.  The M2's boilers were practically the same as the M1's but were not separable - thus the small firebox.  Before stokers were installed two firemen were used on these engines.

Yes.  To fit onto 100' turntables.  Originally purchased for use on the 7 mile Proctor Hill the small tenders capacity was not a problem,  but even after they started using them in mainline service they retained those tenders to the end.

So, with two guys & scoops, was this engine ever retrofitted with a stoker?
Or, did it remain a “hand-bomber”?

Seems like it carried a deeper firebed, than the later SuperPower
Designs.... that burned thin beds on broad area grates.

4 independent cylinders can surely drink a lot of steam, if pulling all those cars.

As mentioned, they carried two firemen before they got stokers.  DMIR and its predecessors LOVED to put as many appliances as they could on their engines.

How 'bout this one taken in 1952 of No. 202.  Sorry, I've lost to whom credit should be given.  Still a compound, so there are not "4 independent cylinders", and still has her separable boiler!!!  (Note the circumferential joint right ahead of the uniquely located air reservoirs.)  With an Elesco feedwater heater!!!  The front portion of the separable boiler was taken out of service but remained in place stripped of its guts and water carrying capability.  Steel scrap was carried in the empty shell to offset the weight loss.  Scrapped in 1953. Don't know how that affected their drafting, but they reportedly took a long time to cool off.

Love those neat clean lines....NOT.  

That's amazing.  A seperable boiler filled with scrap metal.  WOW.   

Pardon my ignorance, but what is a separable boiler?

Love those boilers with everything in the world on them.  Odd place for a elesco feedwater heater.

A boiler with a separate section, attached onto the front of a conventional boiler, which contained a huge feedwater heater and, sometimes, a reheater.

In most cases it was bolted on, but there are a few examples that were "hinged", and turned when going around curves!

This has been brought up a number of times on Trainorders, and a search of the Steam Forum shows many details.

Wow...

Reconstructing all those references musta’ taken all night...

As far as failures in function,
It’s right up there with 1890s compounding, steam turbine locos,
On-Board water treatment equipment, early stokers, more than 5 driving axles ( in one frame), smokebox superheaters, “tri-plexii”, etc...
