Product Description

The is a model of a common type of ore "jenny" used in Michigan by the Chicago and Northwestern Railway and the Lake Superior and Ishpeming RR. This particular car is often referred to in modeling parlance as a "Michigan type" ore car, as opposed to the shorter, wider cars known as the "Minnesota type". The Minnesota type has been offered by N-scale manufacturers in the past, but up until now the Michigan type has never been available in N scale.

The specific prototype for this particular car is one of the most common sub-varieties of the "Michigan type". It is a CNW ore car with taconite extensions as it appeared in photographs from the 1970s. The general design is common to most iron ore cars used in Michigan, and this model can be used to represent almost all of the ore cars used to haul taconite pellets in Michigan from the 1960s through the 1990s. Some of these cars are still in use today serving their original purpose on the same rails.

Trucks and couplers must be purchased separately. BLMA 70-Ton ASF A-3 Ride Control N-scale trucks are recommended. This listing is for two cars. They come attached to a sprue along with coupler covers and truck attachment pegs. A spare coupler cover and truck peg for each car are included.

Cleaning, Painting, and Assembly:

1. Using a small plastic container, immerse in a "Purple Brand" engine degreaser (brand names: Purple Power, Super Clean, etc). Wear gloves and eye protection. Allow to sit for one hour. Gently brush sides with soft brush. Remove and carefully rise with fresh water. Allow to dry for 24 hours.

2. Remove cars from sprue by carefully snipping or cutting near the bolsters. Trim or file bolster smooth. Remove sprues with coupler covers and truck pegs and set aside.

3. Apply a drop or two of very thin CA glue to each stirrup, allow to soak in. This will help prevent breakage during handling. You can also use the same technique for corner posts or other fine details. It is very important to do this especially if your model was printed vertically as the model sits. You will be able to tell because the print lines will be horizontal. This tends to make vertical details more fragile. Think of it as the grain in a piece of wood. A long detail like a ladder or a stirrup is stronger when its length is with the grain, weaker when the length is across the grain. By impregnating the detail with thin CA glue you create a composite material by bonding the layers (or "grain") more tightly together. Dimples have been provided on the two corners above the ladders. If you wish, these can be drilled out with a #80 drill and separate wire grab irons can be glued in place. There are four grabs on each corner. See photo. The grabs are a scale 18 inches wide.

4. Lightly apply primer and allow to dry. Examine car and carefully sand or trim any flashing or roughness. Prime again, paint, and apply decals. Paint truck peg and coupler cover sprue at this time.

5. Remove truck pegs and coupler covers from sprue. Install couplers and covers. Apply thick CA to corners to secure coupler cover. Before securing trucks in place, test them to ensure free movement. Wheels with large flanges may contact the frame. Low-profile wheels will work better. Once good operation has been ensured, position trucks and press peg in place. Do not press all the way in, leave a small gap for side to side and rotational movement. No glue is needed for truck pegs, friction will hold them in place. If there is paint in the hole and the peg will not fit, gently wallow it out with a tooth-pick or an appropriately sized small drill bit.

Note: If you find the car is too light, secure lead shot in bottom of hopper. Low temperature cerro type alloys can also be poured into the hopper. Only use as much as necessary to provide good operation.
