I'm building this all from scratch, so I'll be flying by the seat of my pants. That means I'm open to suggestions should anyone know of a better way of going about things.

And so it begins!
Step 1:

Getting under the Beast

The Coal Drop Zone! I figure I'll build her from the ground up. In my photo references of this area, the details are sparse, so I'm going on some of what I have seen (picture wise) of other such structures, and a good deal of guessing.



Printed off my drawings in HO scale and then measured, scribed, cut and stained this piece.



But I messed up . . . scribe lines were off a bit and missed a few crucial details.

So I bought an "Incra Ruler" that I stumbled across at "Lee Valley". The tiny holes in it mean you can use a pin or a technical pencil to mark for greater accuracy and speed!

And it worked like a charm!!!






second try . . .



Okay, I like how this turned out but the stain I used earlier went on much to uniformly, so I'll fiddle with that later, on a practice piece and then stain the real deal when I've got that down pat.

I'm going to measure and cut out all the remaining parts for this foundation piece before staining commences.

Now as I thought about this next part (the Bents under the structure), I decided to make a template . . . I think I've seen some fellows on this forum do something like this before.



and cut out the parts . . .



That's all for now.

You could be correct, but as I watch the video, the oil or kerosene, if that's what it is, is not spraying out but gushing out. I would imagine that using kerosene or oil in such volume, would be rather costly compared with water not to mention the accumulation of oily residue running down the tender and accumulating at the foot of the coaling station.

It would be an unholy mess!



Makes sense. I thought maybe they had some kind of nozzle on the end that would give a spray pattern. As you said though, "it comes out in a flow", so it must be water.

After our little discussion here, I did some digging on the internet and found something about coal and the dust it produces as follows . . .

The US Department of Transportation classifies coal dust as a “pernicious ballast foulant” that can weaken and destabilize rail tracks.

Coal dust deposits sometimes cause spontaneous fires, and in 2005, for example, coal dust that had accumulated in ballast, the layer of crushed rock that supports rail tracks, caused derailments.

If shippers wished to reduce or prevent coal dust from escaping, they could do so by filling cars less full or covering them with tarps or chemical sprays. However, these measures run up the cost of moving coal, so coal shippers prefer not to employ them.

Spontaneous combustion of coal is a well-known phenomenon, especially with PRB coal. This high-moisture, highly volatile sub-bituminous coal will not only smolder and catch fire while in storage piles at power plants and coal terminals, but has been known to be delivered to a power plant with the rail car or barge partially on fire.

Outside of confined environments, PRB coal does not spontaneously explode or burst into full flame, but under the wrong conditions it can self-ignite and burn slowly even while it is riding the rails.


Wow, never knew coal dust was such a problem!

I wonder if 'anyone' is listening . . . Subtle but sneaky Kris

I was just thinking about how I might do just that; checked my inventory of polystyrene and brass wire. Looks like I have what I need!

They would just shut the water off in the winter.
So loading coal was bit dusty/dirtier in the wintertime than in the warmer months.

Looking at that exposed piping makes me wonder what they did in the winter. Wouldn't those pipes freeze?

Received Ian's book today. I watched the video showing the water cascading over the coal. You are right, my previous picture was a close-up of the sand pipes.

From my files I pulled this close-up . . . that clearly shows the pipe that carried the water.



cn-scale Posted - 12/05/2019 : 10:34:23 AM
The hose you're pointing at seems too big - I would guess that's a sand hose?
Maybe the water hose was run along the underside of the catwalk railing making it virtually invisible in photos.

If you've purchased Ian's book just send him an email and he should give you access to the video. Hopefully he won't mind if I post a screenshot here just to illustrate what I'm talking about.

Hey Chris!
I am presently waiting for my copy of Ian Wilson's 'Speed Graphics & Steam 1958 Vol. 2; to be delivered. I have not seen the video you mentioned. I am however, surprised to hear that water was used while the coal was tumbling down the chute into the tender! I wonder if that's what these hoses were for?

Hi Robert - I haven't posted very much but I have been following and enjoying the details of this build.

I also thought I'd mention (in case you weren't already aware of it) that Harold Kinze recorded a lot of footage around Palmerston in 1956, and there is a 90-second clip of locomotive 2629 being fueled at the Palmerston coal tower. Ian Wilson is offering the footage as a bonus to anyone who purchases his latest book (ianwilsonauthor.com).

The clip is pretty dark, so it's difficult to pick out much detail (at least not as much as you've found in photos already) but it does show that when the chute is opened and coal starts to pour down into the tender, the operator opens a valve to add a stream of water on to the coal. Presumably this was to minimize dust? Anyway, I just thought I'd mention it in case you're interested -- not that I'm suggesting you need to add water hoses to your model!

Even the little pile of just 18 is cute.
Now it's what we do with those nice little arranged piles that really counts!
Get back to work!

I hear you Greg . . .

It's been a slow build to be sure . . .

Currently I'm playing with the diorama's dimensions.


This measures 48 x 25 inches vs. the 36 x 20 inch, originally being considered.

Upside to this dimension is that I won't be cutting off any of the turnouts like I would be in the 36 x 20 one . . . downside however, is the size, it's getting clumsy big.

And so I'm thinking about which way to go with it.

As well, I just completed this detailed sketch for my YouTube video on the Sphinx sculpture. 4th Episode is nearly ready to be uploaded.

Many irons in the fire slow things down.

Where a RR had the room, and expected employees to be working between tracks occupied by cars, they'd use 15 foot or even 16 foot track centers. If I was between two cuts of cars on 13' track centers, I'd need to turn sideways should one move unexpectedly, and I'd have a very tense interval if both sides were moving.

Tie spacing also varied with the expected speeds and loads on track. Over the last century, main line tie center-to-center distance shrank to the current 18" as equipment got heavier and speeds increased. But 22-24" is still used for light-duty track, and 1940s branch line yards might have used a few inches more. CN historical documents might have details.



Thank's James, that's great information from track side! I'll start looking around to connect with some CN historical sites on the internet, I could learn a few more things there no doubt!
