Overdue update

After a long wait the, trucks for one of the Skokie Valley cars came in. (Both cars had the same trucks.) While I’m happy to have finally gotten these, they did not arrive without a small bit of frustration. The order was for a power truck with two Magic Carpets and a trailer truck. What I received was a pair of power trucks, each with one axle powered. I could alter the trucks to my original specifications, but I’ll probably just leave them as they are and go from there.

These are NorthWest Short Line Magic Carpet IIIs installed in Q Car Baldwin 8430AA sideframes. I opted not to get the sideframes with North Shore trolley beams so that I could devise and 3D print my own insane trolley beams with free hanging third rail shoes. If this fails, I'll acquire the appropriate Q Car trolley beams and attach them myself.

I took the opportunity of having a day off for Memorial Day to head out to the Illinois Railway Museum. They had (I believe) five trains in operation: a pair of CA&E woods, a pair of 4000 series “L” cars, the Zephyr, a steam train, and the CTA’s 2200 series cars. The 2200s were on town shuttle duty, operating on a short trip from 50th Avenue to Jefferson Street (the western end of the line) and back.

While I did take the opportunity to ride some trains, I was primarily there to complete and expand the measurements I took back in October.

In addition to more CA&E and North Shore equipment, one of the things I really want in O scale is a pair of 2400 series cars. Unfortunately, their numerous compound curves are fairly daunting and I haven’t yet conceived of a method to reproduce them properly.

Instead of attempting to tackle this task outright, I decided to try something “similar,” but with a much simpler design. The 2200 series, with its rectilinear forms and multitude of sharp angles was the clear and obvious choice. Drawings for the 2200 series were already available in CERA bulletin 115, Chicago’s Rapid Transit Volume II: Rolling Stock/1947-1976. I started with these drawings and then moved to taking field measurements at IRM. The plan was to do this at the end of the season in October and work on them over the winter, but the museum threw a monkey wrench into the works by moving the 22s away from the 50th Avenue station with its high-level platform. Here was the chance to rectify the situation.

I arrived on site around 9:30 and wasted no time in getting to business.

For the moment, the aim isn’t to produce a whole car. (That is, of course, the eventual goal.) I want to see how well I can produce a car side and then improve the design or (if satisfactory) continue the car to completion. To this end, my efforts were on filling in the missing measurements on the car sides and things couldn’t have gone more smoothly.

I have no idea what led me to believe that this would be a relatively simple “warm up” project. There are so many “minor” details which (if ignored) would end up drastically changing the shape—and therefore the look—of the model. Even without complete measurements, the car is definitely beginning to take shape.

Due to the costs involved, I’ll print a test “strip” to determine how well things are coming out and if there is anything that needs to be fixed. (Shapeways gave me a warning about the grill for the vent at the bottom of the car and I want to see how well this comes out before shelling out for the whole side.)

Ultimately the kit will be made of 5 parts per car, with the sides of the cars being produced as one long piece. Fortunately the car sides are just short enough in 1:48 that they barely meet the length limitation for Frosted Ultra Detail. As of right now, each side will cost just under $100 to make, but this doesn’t factor in the reduction in wall thickness at the doors or several other details that (when finished) will reduce the total material used.

I also got a few measurements for the Form 5 coupler. (I’d been having some difficulty with one particular area which I couldn’t get to look right.) With any luck I should be able to have a pair of 1:45.2 scale couplers for the 3200s rather soon. Once successful, O scale couplers will follow.

March in Review

Let’s get straight to the point; I spent a lot of money this month. Even though I’d planned on spending a good deal of money on models this month, my actual total greatly exceeds my anticipation (and this doesn’t even cover routine things like food and bills). I had a number of other projects (not model related) that also cost more than expected, so April will almost certainly be a very quiet month around here.

With that said, it seems like a good time to stop and reflect on a very expensive (but good) month. March is the month of the Chicago O Scale Meet (also known as the March Meet) and associated open houses at various trolley layouts. Preparation for these two prompted me to get back in gear and begin working on the 3D model of CTA’s form 5 coupler.

Ultimately this design wasn’t finalized in time for the open houses (I was only able to attend one) and the design work is still ongoing. The continuation of this project should be a nice one to carry on into April.

Before the meet I was able to get my hands on a Clouser North Shore steel coach. Although it did not come with trucks, I did get a good deal on it and am very happy with my purchase. The following week was the March Meet and there I bought a brass North Shore 170-182 series coach. Acquisition of this car has enabled me to outline and define my projects for the North Shore Line. I’d already decided on modeling the North Shore circa 1952/1953 (the same years for the CA&E) and the addition of these two older steel cars has led me to separate my efforts into the creation of two trains: Chicago-Milwaukee via Skokie Valley (the combine and upper 700) and a Chicago-Waukegan Shore Line train (the “older” coaches).

I have already ordered a motor truck set that would be applicable to either car on the Skokie Valley train, so I’m waiting for that to arrive. I’ll have to construct a test track pretty soon, which I suppose will be the very beginnings of my layout.

Also at the O Scale Meet I bought a pair of pantographs to turn into sausage. The shoes on these will be cut apart, to produce four “single” pantograph shoes. Each of these will be mounted at the end of a pair of four-spring horizontal trolley poles. I still need to buy a total of eight trolley poles for car 2 (the 1-50) and car 52 (the 5000) to make this. As a result of... overspending... I probably won’t begin this phase of that project in April.

After the March Meet I went back and made complete 3D models of the 3200-series snowplows. After increasing the size of the nuts so that they would register at Shapeways, these were sent off to the printer. They arrived on Monday and I am extremely pleased with the results. I’ve already made these available via the Ravenston Car Company at Shapeways. (Shameless self promotion!)

In continuing work on the 3200s, I ordered a set of wheels from NorthWest Short Line. I had planned on mounting these inside of cheap, temporary trucks (shop trucks) but I’ve abandoned this idea in favor of 3D printing my own set of “test trucks” which will enable me to try a few things out and see how well this will actually work. Unfortunately, 30” wheels are on backorder for about a month, so this particular project will probably have to wait for a while. In the meantime I’ll see if I can gather some pictures of the Duewag trucks with which the cars are equipped.

I know someone who claims (strong emphasis on “claims”) that he has access to equipment to make metal casts and, if all goes well, I should be able to make molds of the 3D prints and produce a series of metal trucks.

Even after the end of the March Meet March continued to be a money spender! I found another brass 1-50 series car and didn’t hesitate to grab it. To model the four basic iterations of Skokie Swift equipment as planned, I need a total of three of these cars: one as for a single-unit 1-50 and two for a double-unit 60. I now have two.

My first 1-50 has a dent on one end which I should be able to hammer and fill back into shape. Regardless of how well this turns out, the original (dented) 1-50 will now be used as part of the 60 pair with the dented face being positioned between the cars to minimize its visibility. The new car will now be the single and will get the CTA designed trolley-pans.

I also started work on a 3D model of the resistor grids for the 3200 series. This model uses measurements taken from the pair of 2400-series cars at the Illinois Railway Museum. There are subtle differences between the 2400 and 3200-series equipment that I have to account for and I’m currently working with the design to get it right.

The benefit of creating this model in full scale and then reducing it is that it can effectively be used to create specific models for the 2400, 2600, and 3200-series cars with only minor variations in each and scaled appropriately to 1:45 for the 3200s and to 1:48 for my planned 2400s and 2600s.

The 2200-series cars (which I have already started designing) used a resistor set that was substantially different than those used on the later cars. During my last trip out to IRM, I didn’t take underbody measurements for the 2200s, so I won’t be able to continue work on that particular set until I make another trip out to Union.

Finally (my wallet has its fingers crossed that this really is finally) I found a power truck set that would be appropriate for either car in the Skokie Valley train. It matches the truck I ordered from NorthWest Short Line, although at present I don’t know if the motors are Magic Carpet IIs or IIIs. The main impetus for getting this truck was the fact that I was able to get it for a substantially lower price than normal.

Moving forward into April my projects are most likely going to be all 3D modeling as this can be done at no cost. I plan to finish the form 5 coupler, work out the kinks with the resistors, and begin creation of an underbody set for a 2400-series pair (since I have photos and measurements on hand for that). I’ll also be continuing to fabricate the replacement car floor for the second 3200-series car.
