Those wheel-slip episodes were interesting to say the least.  Lots of leaves, probably wet rail...  it's to be expected.  Was that booster working?

Nice videos today.  Thanks for posting them.

I've only seen one T-1 run, but it didn't run like that. If it had, that hill in Tacoma wouldn't have stood a chance...Great video, thanks!

Cheers, Dave

Hillcrest, the T-1 that was run in Tacoma if I recall had been converted to burn oil, it never ran well in thta configuration. I believe it is in Ohio and is in process of conversion back to coal. and restoration. I don't recall maybe it is 2124?

Not #2124, which is in the Scranton Steantown collection. The failed "Tacoma Hill" project was #2100.

The loco in Tacoma was 2100, now completing restoration 
in Cleveland, as I write this...

Back then, I was working for investor, John Marino (RIP) who wanted 
to determine if 2100, at that time, might benefit from an infusion of cash.

After looking at Tom Payne's (sp) oil-burner stuck through the firebox door 
opening for the coal stoker & firing-table, I understood that arrangement 
would NEVER make steam, in the necessary quantities...
I told Marino to keep his checkbook in his pocket.

There were numerous items and appliances that were non-functional.
So, for many reasons, I knew that 2100 would need a couple of $million 
to be operational.

The reconditioned 2100 will be fitted with a more conventional oil-burner 
arrangement and will be a oil burner --- capable of PRODUCING the millions
of BTUs needed to perform at better steam production, than the best coal versions...

I've been to 2100 at Cleveland, during reconstruction, and they're doing
a fine job....including contracting with experienced folks, with many successful
oil-conversion locos, currently running. And, yes, they know what theyre doing.
Plenty of fire will be produced to power 2100 up the steepest grades!

If you will contribute a generous donation to the 2100 restoration project,
I  will match it, dollar-for-dollar, once your check clears...( 30-day time limit 
on the offer).

I must say haven't seen/heard video with that kind of sound of frequent slipping!
And looks like the steel tires are steaming hot too??
Wonderful video!

Look again... that cloud of white stuff is crushed, sand-dust. from the fully functioning sanders ...

And, yes, the 'rail-washers' are before the first wheel-set of the lead tender truck.
(So that the rear axle of the loco's trailer truck gets sanded rail... the booster
engine drives only the rear axle of the trailer truck.)

In the video, you can clearly see the small steam cloud ahead of the 
first tender-truck.... that's the rail washer!  

Remaining sand on the railhead,  under the coach's wheels can add additional friction,
and stall the train.... that's why you got rail washers on steamers.

No! That is just dust from the sanders. Driver tires would NEVER get that "hot".

Oh, I see about the crushed sand, and I forgot about "rail washers"
Makes sense to wash sand away after booster does its job.

My statement lacked clarity. My intent was to pay a compliment to the operators/crew and to 2102 itself (I know, it's an inanimate object) for what is clearly a locomotive that runs very, very well without taking too much of swipe at the much maligned 2100 while owned by you know who. My observations of "it" were the same as Mr.Camps' in regard to its time in Tacoma, and am pleased by what I've heard that 2100 is also in very capable hands now. I'm assuming the donation part was aimed at me or possibly others, and tho I usually do what I can volunteer and donation-wise in the PNW, maybe I'll see about broadening my horizons in this regard.

Cheers, Dave

The supply of hot water for the rail washer is taken 
from below the top level of the boiler water.... from a source 
near the firedoors, in the backhead.

What's sent to the rail,washer is near 400F boiler water ... which a portion of 
flashes into 212 F water-vapor, down at the rail... but, there is a stream of very hot water,
which becomes visible in the cooler air of the atmosphere.

It really is the 212 F, water that washes the sand off of the rail head.
( Also, appliance vendors marketed rail-washer diffusers which converted a 
   solid stream of hot water, and shaped the expanding water-vapor stream into
   a wide,  fan-like, triangular , water stream --- across the rail head, and washed the 
   the top edges of the rail, even while navigating curved trackage...the rail washers 
   being attached to the front of the 6-wheel tender-truck frame ....

Another advantage to applying the
commercially available diffusers is that they use less hot water, compared to just open pipes —- like 2/3 less water than crude, open pipes at the rail head…)

The safety valve!

It’s great to see the pop UP !

Professionally, having the ‘safety’
lifted was frowned-upon…… ‘wasteage’ concerns, etc…

In excursion environments, it adds
Information to the crowd watching
the fight…. Like siderods, bells and whistles, the public understands
safety valves!

A strong, uphill fight gives the grates
that support the firebed, the greatest
flow of oxygen to the fire bed …..
a REALLY HOT firebed is where you
get greatest, highest firebox heats.
The rate of oxygen flow is what
gives the hottest fires !!

There is a lateral wall of sloped arch bricks up & over 70% of the grate area ….
Its right in the path of the hottest flames from the firebed.

Without a “brick arch”, the long flames and high wind velocities
could dive-into the rear tubesheet,
only partially burned —- the redirected gas-flow allows more complete combustion
and 3,000 degree flame temperatures — when high draft rates make possible the hottest fires !
When fighting long, continuoustrack grades, is when you get the hottest fires…

The modern, “ front-end “, multiple poppet-throttles give much better control of steam flow …
and allows the engineer greater range of steam-flow control through the throttle, compared to
the old: ‘all-or-nothing’, single valve, old-times throttles…

In this case, the fire is really HOT, so the high winds through the firebed, brings the 3000 F flames
deeper into the flues containing the superheater units….

( Only about the first 30” to 40” inches of the far-end of a superheater unit receives hot flame-tips…
.. the much colder boiler water absorbs the heat from the smaller, individual gas-paths inside each of
the superheater flues. The hottest the boiler water can reach, is only about 400 degrees—-and that’s only
over the crown-sheet [‘roof’ of the furnace].

The water temperature is coldest at the lowest areas of the boiler….. so,the beneficial heat of the flames
gets absorbed very quickly, during the journey down each flue…the greatest flue temps are at times like seen
in this video…)

Hotter ‘units’ send hotter steam to the pistons …. So, more volume of steam leaves the units, than enters them…
The slowed steam-flow through the superheater units increases the “dwell-time” of the steam-flow ——
allowing for greater increases in superheat temperatures. The actual steam flow, through the units is slowed —
giving longer dwell-times to the steam — making for HOTTER steam flow to the pistons..,

A lifted safety tells you how hot the superheated steam is — at the piston face…. so, as in this sequence, the
open safety tells us how hot the fire is, about the glowing state of the brick arch, and that the hottest steam is
doing the REAL work.

A strong draft, over time, makes so much heat: that less fuel is needed and the more oxygen, means less
steam is needed,than is actually being produced… What determines the amount of oxygen available,
is the intensity of the draft available.  the lowest amount of oxygen available is going downhill....Flat territory 
requires heavy trains, and the hottest fires are the up-hill fights.... so, it's the engineer that determines the 
supplied oxygen for the firebed.  
 
Another determinant is grate area available for rapid burn rates.
A smart fireman, with a large grate area, can adjust the open combustion 
area by keeping a big mass of glowing coal at the rear of the grate area.
Maintaining a large bank of coal, coking at the rear of the unused grate 
area, is a way that a fireman can adjust-for a  reduction in available draft rates.

The ‘clean’ stack also tells us that very little fuel is being added —- and combustion is nearly complete,
by the time the 3000F flamesenter the flues — surrounded by 400F ( ‘cold’) water….
In this video, the brief period of darker smoke, shows the added heat—- which lifts the safety,
for a brief period…

At these high-draft rates, very little fresh coal is added…. Flame travel-time through the grates
and up the stack, means flame-times are under 1-second, through the firebed and out the stack,
… almost 100-mph winds — are fanning the flames …

So, yes, he’s running with a partially. closed throttle because the steam flow out of the units
is slower than the hot steam entering the units…so, all that excess heat —-lifts up the safety valves …
, because the draft from the heavy train-weight makes for the hottest fires!

( Hotter steam means that there is more ‘vibration-space’ between the
   H2O molecules … the molecules are hotter, --- a more excited state--
-so, fewer of them is needed to get the “work” done.. that’s why "more steam leaves the units,
than is entering the units" !  Higher volume because of greater steam temps).

That’s why we cheer a strong fight, and lifted safeties —- SO MUCH heat
is being raised, and less steam is actually being used —- so, UP goes
the safety!

Yes, on up-hill fights, I cheer open safeties because the fireman is telling the
crowd about where his “is”, and that he’s providing all the fuel needed, and, then-some!

Enjoy !

W.
