Great Northern Class C-1 0-8-0 Switcher #828 - Part II

Status update on the #828...

I was able to rewire the locomotive and it functions on DCC! While this took a while, I can breath a sigh of relief that I have not burned up the decoder.

Unfortunately there is a lot of gear noise still, even after lubrication. It also staggers a bit at the slowest speeds. Any ideas out there short of regearing would be helpful.

Great Northern Class C-1 0-8-0 Switcher #828 - Part I

1949 Minneapolis, MN

The Great Northern operated a number of switching steam locomotives over the years. None were more prominent or lasted longer than the Class C-1 0-8-0 steam locomotives that operated throughout the GN system from WWI to the end of steam. 

The Great Northern updated much of it's steam power in the 1900's and 1910's and buying new switchers was part of that. The GN preferred its custom steamers and the C-1's were ordered in 1918 from Baldwin, just ahead of the US Railroad Administration taking over locomotive orders. "They had the common (at least for the GN) 55-inch drivers and 26-inch by 28-inch cylinders. They were equipped with Walschaert valve gear and piston valves. As delivered, they operated at a boiler pressure of 200 psi (design pressure was 210 psi) with a total weight of 232,600 pounds (all on the drivers, of course) and a tractive effort of 58,500 pounds." (Middleton & Priebe, 2010)

#828 served on the Willmar Division through 1955. Almost the entire class of locomotives lasted until December 1957 when the first were sent off to be scrapped. They outlasted most of their counterparts for the simple fact that they were in good shape and were near their fuel and service locations at all times in yard service.

Most photos place it in service at Minneapolis but this is close enough for me. While never a road locomotive, the limited space I have to model in requires a small GN locomotive to conduct switching moves with, so concessions have to be made. In the future, I hope to get some larger GN steam models.

I have a mint, DC, Tenshodo Great Northern C-1 0-8-0, circa 1960. After lubricating it and adding a Kadee coupler on the tender, it runs fairly decent for sitting in a box for over 50 years. The motor runs fine but sounds a bit like a coffee grinder. What I hope to do with the locomotive is a full DCC conversion and repower. I will do this in two phases.

Phase I:
I hope to install a new LED headlight to replace the jewel headlight on the smokebox. I hope to do the same with the tender light. I will also replace the motor and drive shaft joint with parts from Northwest Short Line. Last, I will run a connector cable to the tender which will house the new decoder, the ESU LokPilot Standard that I picked up for cheap. If I fry it in the install process, it will be a lot better than losing an expensive sound decoder.

Phase II:
If everything works out in Phase I and I am able to run it flawlessly on DCC, I will look to add a sound decoder.

If I can get through all of that, I will weather the model and add detail down the road when my skills are better. All of these tasks will certainly be challenging and at the very least it will be a learning experience.

Ground Goop

Looking for an ideal ground base is not easy but I am happy with the technique that I found in a number of places online. Called "ground goop," this mix of ingredients forms a hard shell over whatever forms you choose to use. I used pink polystyrene but I am sure that almost anything could be used. I found the mixture very workable and a drywall knife worked great for both mixing and spreading. Using a wet finger occassionally was great for minor adjustments as well. 

After about 36 hours even the thickest areas were dry and it truly forms a tough shell. If you are not happy with the contours, the dried goop will readily accept additional applications over the top of it. I have been told that water will loosen the mixture with some work, but I have no desire to find out...
























Finding the right base color is important, even when you plan to add scenery over it eventually. The color will show through where scenery wears off on the surface, where there isn't enough coverage, or if the surface is pierced or dented by anything. Behr "Underground" is pretty close to the dirt color found in Kandiyohi County, Minnesota. While I could have chosen something even darker, I like the dry soil look vs. a darker, wet look.

Below I have posted the ingredients that I have used for my modules, although this is by no means the only way to do this.

LIST OF INGREDIENTS:

  • 32 oz. Vermiculite - Can be found at Home Depot.
    • A finer vermiculite would probably be better but I use what's readily available year round and this is the only variety at the Home Depot that I was able to find in stock.
  • 32 oz. part Celluclay -  Can be found at Michaels.
    • The amount of glue used is flexible 
  • Mix with small amount of water to your desired consistency.
    • Oatmeal consistency works well.
  • 8 oz. Paint #N200-7 Behr "Underground" -  Can be found at Home Depot
  • 24 oz. Elmer’s White Glue -  Can be found anywhere.

It isn't often that I spot any interesting power or equipment at Berthoud, Colorado. The town used to have a number of industries on its siding but now only sees maybe a boxcar or two per month for a printing company and a machining company. Recently though, I spotted this unique piece of MOW equipment. After its second visit to town, I was able to catch these photos.

Looking at the work train, I was curious as to its use. The answer is pretty interesting. The Herzog 174 was built by Herzog Railroad Services, Inc. The unit serves multiple uses and is typically controlled by one operator. Here is a a link to the corporate site showing the unit's capabilities.

Here is a link to the unit in action at Boulder, CO last fall.

I'm not entirely sure why the unit is in Berthoud. Some ballast
piles have been delivered but the unit has been here for at least
2 weeks. Could it be a new industry spur, work on the line,
storage? Time will tell.
