I started building one of the new Branchline REA cars, and it appears to me that there should be a rod that starts at the lever on the brake cylinder and heads in the direction of the brakewhel. Or were these reefers not set up like a typical freight car and the handwheel rod is hidden?
This rod will be easy enough to add, but I want to make sure I should add it before I do. A photo on page 66 of RPC7 shows a hint of the chain that connects the rod to the lever.
