I think with the announcement of the SDp45 from Athearn, I am going to have to trade out one of my designated models and replace it with an SDP45. Ex EL unit. It would be to much fun to model this. I'll have to update my web site and correct some spelling errors. I am still trying to figure out what ore car I want to use. Even considering designing and building my own. I found a layout drawing on American Railcar Industries, Inc. web site of an ore gon. I would use that drawing and reduce the height of the car. Make is something like 1350 cu. ft. capacity like the cars used by Cartier up in Canada. I think I understand how to do the frame. I'll use Moloco non-cushioned draft gear and ExactRail truck sets and naturally Sergent couplers. I'll see if I can cast the rest. It will be a fun project. If I can do it in HO, then I will also do it in N. I am going to model CSR in N as well. Slightly different power (40's, 45's & 40-2's), but still model it in N. I had to much fun at the St. Louis RPM meet and was able to run my CSR power on the layout that was setup. When I got home, I dug out my latest CSR project (three ex QNS&L SD40-2's) and started in on them again. So units 504, 505 & 506 are on the bench. It took me three months to get back to this point, but I am back and really excited to get some models built. Running my models made a huge impact on me. It is very interesting to me because while at the show I was not in the least drawn back to full prototype modeling. There were a lot of great models to view and such, but I still REALLY like the Proto-Freelance idea. I had a lot of really nice compliments and quite a few people asked if it was a real railroad. That was fun . Many of the viewers said the paint scheme I chose really made it believable. So I am off and running again. I am thinking of starting another video series on the models I am working on now. Thinking about it.

This is wonderful news. Though your N-scale is awesome the HO is sweet too
Great idea on using the SDP45 Ex-Erie. KP will be doing the same when they are out.
For the ore cars, what about beat up secondhand ore jennie's from the DMIR maybe, MDC/Athearn makes them, just a thought here so you can run trains while you build your new fleet of cars. The SP used these old jennies for rock service out of San Antonio to Houston and usually had about 40 cars in a train. Again this is just thinking out loud.
Anyway great to see the CSR moving along.

I'm really happy to hear that the Copper State Railway is back from the dead! Watching and following your builds for you SD40 fleet has been great thus far and I'm happy to see it continue. I've been slowly developing a ore-hauling shortline that interchanges with my primary railroad. A few years ago, I found on eBay a guy that has been selling a ton of old MDC/Roundhouse cars. Through this seller, I've amassed 80 ore cars that will eventually be painted up for this shortline. The link below is for a current auction on the hi-side version of the car (there are other auctions for the low-side version and the DMIR style cars as well). www.ebay.com/itm/RCR-MDC-26FT-high-SIDE-TIGHT-BOTTOM-ORE-CARS-5-CARS-/350849247164?pt=Model_RR_Trains&hash=item51b03ea7bcThese cars might be a good base for your project cars, or a decent stand in until whatever you end up scratchbuilding is serviceable as Anthony suggested.

Nice to hear the HO CSR is going ahead. Looking forward to seeing the ex QNSL units take shape.

That would be great I thought your videos where the best on the net and they are what got me started in to detailing my locomotives

Always good to see your own models on the move isn't it? I've only got a Unitrack roundy round setup but even with only a pair of my SD70Ms and 30 ore hoppers it gets my juices going to get on with building the 'big' layout.
Looking forward to seeing more!

Thaks all. I am going to start a new video session on the QNS&L models. Right now though it is just to blazing hot in the garage. But I will get it going very soon.
grdmco. No doubt. The great thing too was it was a weathered 30 car coal train. It was so much fun listening to the locomotives notch up an drun that train around. A layout like that in N would be SO GREAT!
I finally stopped fighting the scale thing and when I want to model N, I model it. When I want to model HO, I go for it too. N will be my primary scale, but as I mentioned. Not until I get some detail parts going so I can bring them up to the level I am used to modeling at. I can work on my freight car fleet though.

From my research, copper concentrate is VERT heavy. If I read it right, 1 cu ft weighs in at 2.76 ton. This is the only information I could find on the weight per cubic tonne. forum.bulk-online.com/showthread.php?8843-Road-Transport-of-Copper-Concentrate. I figure it is in cubic tonne since the question comes from Thailand. So if my calculations are correct. 2.5 metric tonne = 2.76 ton = 6085 lbs. A G35 ore car LD LMT is 164900 lbs. = 82.45 ton. CU FT capacity = 1324 cu ft So a G35 ore car can load approximately 82 ton of copper concentrate which is approximately 30 cu ft of concentrate. Can anyone tell me if I am completely off my rocker or did I actually do this right. Or is my copper concentrate weight not correct? Thanks. Brian

Depends on the copper concentrate, is this being shipped in powdered, chunked or liquid form?

Powder granule form. The copper is being concentrated 7000 feet underground and then brought to the surface for shippment to the coast. It will be dry powdered or granualr form. I know it is a very fine substance. As fine or finer than grains of sand. I just have a hard time believing that 1 cubic foot can weigh in at over 2 tons. That is some pretty heavy material.

I think I found a site that has better information.
Copper concentrate is "200 Concentrate Density, pounds per cubic foot". So I read that as saying 1 cubic foot of copper concentrate is 200 lbs. That sounds more reasonable than over 2 tons per cubic foot.

Sorry, reading more I believe the weight was for magnetite.

OK, I found out where I was going wrong. I found a better site with the specific question asked of "how much does 1 m3 of copper concentrate weigh on average. The final answer was with 10% moisture between 2.2 - 2.4 t/m3. I'll use 2.3 t/m3 for my calculations.
1 cubic meter = 81.224 cubic feet 1 metric tonne = 0.984 ton 0.984 ton = 1968 lbs
I have re-evaluated the ore car I am going to use. If I have to design and build my own, it will be a long time befor I ever get a fleet of cars. I have to be realistic about that. So I have decided to use the Athearn 26' low side ore gon. The old MDC car. I lik eit a lot and it is very easonable that the COpper State Railway purchased a lot of these cars used and will send them to a car rebuilder to be completely rebuilt from the ground up and have hoods designed to fit the cars. I bought my first car today to get the prototype all setup for wha tthe ore cars will look like when rebuilt.
So to continue with my calculations. The ore car specs are as follows.
CAPY 170000 LD LMT 170800 CU FT 1304
So, this car can handle approximately 86.5 tons of copper concentrate which rounded down comes out to be 170,232 lbs. If 81.224 cu ft = 0.984 ton or to round that off to whole numbers, 81 cu ft = 1 ton and the car can handle 86.5 ton of copper concentrate, then 86.5 ton x 81 cu ft/ton = 7006.5 cu ft. The car has a limit of 1304 cu ft, so we can load each car with 16 ton of copper concentrate. That is 16 ton x 81 cu ft/ton = 1296 cu ft of concentrate. So if my calculatios are correct, that is an almost fully utilizing the capacity of the car.
So does that all sound about right?

Dang, made a mistake again . I was figuring at 1 t/m3. It is 2.3t/m3. So I have to go through all this again and figure it out. Man, math kills me . 1 cubic meter = 81.224 cubic feet 2.3 metric tonne = 2.54 ton 2.54 ton = 5080 lb ORE CARCAPY: 170000 LD LMT: 170800 CU FT: 1304 81.224 cu ft = 2.54 ton 1304 cu ft / 81.224 = 16.05 16.05 x 2.54 ton = 40.78 ton 40.78 ton = 81,560 lbs. I think I got it right this time. So the car filled to cu. ft. capcity is loaded with 81,560 lbs which is well under the LD LMT spec.

CAPY: 170000 LD LMT: 170800 CU FT: 1304 81.224 cu ft = 2.54 ton 1304 cu ft / 81.224 = 16.05 16.05 x 2.54 ton = 40.78 ton 40.78 ton = 81,560 lbs. I think I got it right this time. So the car filled to cu. ft. capcity is loaded with 81,560 lbs which is well under the LD LMT spec. The capacity data you have listed looks pretty good. Looking at the capacity data from the PC/CR ore cars that Highball offers decals for, the capacity values are: CAPY: 154000 LD LMT: 176900 LT WT: 43100 CU FT: 1324 The prototype cars are very close to the MDC cars (close enough for me). Jim is currently printing up decals for me to decal my cars in the near future.

I am going to have Jim do my decals for these cars. I need a few other items, so I will do the dimi data as well.
The car is in the stripper, wheels are painted, truck frames are painted and the ladders are grit blasted. I am going to have to design the lid and also I need to decide the color of these cars. Nothing fancy. one of th efollowing.
Oxide red with white lettering Mineral red with white lettering Light gray with black lettering
I am leaning toward the light gray. But I was also thinking maybe somehting not so standard as the colors I have listed above, but I guess the colors listed above handle wear and tear better than bright colors. I have time to figure that out though. I need to design the lid first.
