I was struggling to find some photos showing the brake component layout of these cars so I didn't make any progress beyond dressing up the spines and narrowing the platforms for awhile. A big mental block for me was the even number of platforms, since modern spine and well cars are almost always made up of three or five platforms. The brake system is applied to the end units and every other unit with the even numbered platforms acting as a car-shaped drawbar more or less. Finally, I realized that these were among the first cars built after Santa Fe sold their 10-Pack patent. Using the 10-Pack drawings, I simply omitted the end units of the 10-Pack and patterned the brake system after the remaining eight platforms. It may not be correct, but considering the difficulty I had in finding any photos of the brake system, I'm not too worried about being proven wrong.
