The braking system for Chicago & North Western #1385 consists of an iron shoe pressed against the steel wheel. The shoes are held by the brake head and held on the brake head by a key. The brake head is attached to the brake beams and through a system of levers and hangers the brake beams get their motion and power from compressed air applied to the brake cylinders.
The brake heads on the 1385 were worn out so we ended up having a pattern made and getting new brake heads cast from steel. Project volunteer Pete Deets got a couple photos of Steve machining the last head to fit the curvature of the brake shoe. There are also a couple of shots of the key, head & shoe on the bench.
Since these photos were taken the brakes have already been installed onto the 1385’s running gear. SPEC Machine is now turning its attention back to the cab. Upcoming tasks include installing the cab roof’s protective rubber roof installed to keep the weather out and installing the cab electrical system.
On the southern front, progress has continued to at the Continental Fabricators shop in St. Louis, Missouri where the 1385’s new boiler is taking shape. In mid-July 2018, the boiler underwent the first of what will be numerous inspections from the Federal Railroad Administration as the locomotive comes together. In the process of going through its first inspection it earned a boiler number, 9622, for FRA tracking purposes. This means for the first time the new boiler is officially recognized as part of the locomotive. The inspector spent a couple of hours reviewing the parts and pieces and was satisfied with the work to date.
