Re: Unusual trucks on gon in American Smelting photo

A little housecleaning on my last post:

One of the SP series was 34', another was 36+'.  Both close-ish to 34'.  There might be other candidates.

I did it anyway.  And, yes, the truck wheelbase comes in around 5 1/2 feet.  Which is remindful of the dimension that Dennis came up with by a different method.

Well, well, says I.

Contemplating on all this, I thought:  "What if the inside length wasn't 40'-ish?"

So I went backwards from the truck wheelbase to get the IL.  Which comes up at about 34'.  In that case, I could note that Southern Pacific had a couple of gon series with that IL.  Nothing shows up for UP, that I can see.  But...........

In other words, if the truck wheelbase is "standard", which it appears to be when compared to the neighboring truck, then it would seem likely that the car was shorter than the typical 40'.

Even by getting a "sale price" on the Wiking tractors, it was a pretty expensive load (I used to refer to the original version as my "$90 load on a $10 flatcar") but I was only making one of them.

Todd, thanks so much! I had forgotten about those trucks, and they are perfect. Not roller bearing like the MDC, and since I don't want the roller bearings, that works out well.

Hi  Richard,

I looked on eBay for Roundhouse SP ore cars, as that's where I thought the MDC trucks were used, but the photos in the auctions I found were not conclusive.

Have you seen Cory Bonsall's trucks used under the Utah Coal Route 70t gons?  Here's a link to his auction for them with pretty good photos:

I took a quick stab using Charlie's suggestion and got 5-8.  Pretty close to 5-6 given the fuzziness of the photo.

Re: Speaking of decals

Re K4 decals --

I recently ordered four boxcar sets, and was amazed to see them in my mailbox in three days. They catalog a huge variety of roadnames, including some real oddballs most of us would not have on our shopping list. Very tempting to come up with projects that might use a few of them.

Based on experience so far, I'd rate them as very good. Things seem to be the right size and font. Not up to thoroughness standard of Speedwitch's (but how many are?!). The film is reasonably thin. 

When it comes time to order decals for the next round of projects, they will be high on my consider list.

I hate to say this but Ford sold an aftermarket kit to modify the exhaust on 8N tractors to where it resembled the as built Ferguson. The stock exhaust interfered with some implements.

I think “not opaque enough” is a common complaint about ALPS printed decals if you want to model a new(-ish) paint.  For faded and/or weathered lettering, I’ve heard (and experienced) that ALPS works OK.  Buyer beware, as usual.

Striker casting drawings…and many more!

For obvious reasons, we have cancelled two of the third weekend archives work sessions at the SRHA archives building at TVRM so far. We typically have 10-12 people come either/both Friday and Saturday of the sessions. (Dates are on the SRHA web site at www.srha.net.) The archives contain the linen originals of virtually every Southern Railway and Central of Georgia freight car (STMFC) and Southern passenger cars, the Executive Dept (SR Presidents’) files from before the creation of the Southern and all of the files from Hayne Shop in Spartanburg, SC in addition to several large photo collections of all of the railroads in the Southeast and beyond.

Anyone is welcome to attend and if they have plans to visit TVRM at other times, one of us may be able to be there to meet you. Contact me or archives@....

The attached photo is the just Presidents’ file row in the archives.

Re: Density of coal

Yes, you want bulk density . . . . different for lump, stoker or pea sized coal. Then you need the heaping rules for different railroads.  N&WVGN used 15" and C&O 10" max.

Subject: [RealSTMFC] Density of coal

 

I’m working on a problem involving the density of coal and need some help.  Does anyone have a wheel report containing cars loaded with coal that have the weight recorded?  What is the car and weight listed?  The wheel reports I have do not include car weight.

 

I’m asking because well documented coal densities you can find on the web are all densities based on ground coal (think ground coffee) which is done specifically because rail shipped coal, being larger, has substantial air gaps that lessen the overall density of the load.

 

IOW the published numbers are going to be higher than the same cubic volume found in any hopper.  I’m looking for the later number.

Dave,

Give the attached Green Bay & Western conductor's train book from 1945 a try. It is from my collection.  Lots of coal in there, much of it going westbound from Green Bay (station 0) to the paper mills in Wisconsin Rapids (station 96). Some of it in boxcars. Most of the trains in there are mainline GB&W freights.

Re: Density of coal

In Karig’s Coal Cars book, there is a table of coal bulk densities by region on Page 2. 54 to 59 lb/cu ft is roughly the range for anthracite. For bituminous, the range is about 46 – 54 lb/cu ft.

 

The ARA used 52 lb/ cu ft when designing standard cars.

It was a simple case of measuring the length of a known dimension (half of the IL) and measuring the wheelbase length in the photo, and doing a ratio.
I went about it a different way... I downloaded the high res TIF, blew the area up, and reasoning that at that distance the adjacent hopper car is essentially the same distance from the camera, simply used a caliper to compare the wheelbase to the T section Bettendorf trucks on the hopper. They are essentially the same. Possible explanation for your results: 1) what you thought was the center wasn't, or 2) the gon is 40 feet long rather than 46.
