Weld Repairs and Additional Progress at SPEC Machine

Work on the restoration of Mid-Continent’s ex-C&NW R-1 class ALCO locomotive, No. 1385, has quietly progressed through the summer months at SPEC Machine near Middleton, Wisconsin. Project photographer Brian Allen stopped by SPEC Machine’s shop on Tuesday, September 16, 2014 to provide some views of the recent efforts.

The photos catalog the extensive weld repairs completed on the locomotive’s frame over the summer (see July 1 post for additional details).

On the day of the visit, work and discussion was centered on the spring rigging equalizers. A locomotive’s spring rigging distributes the weight of the locomotive over the various wheels. Without equalizers, even small undulations in track elevation could cause substantial variations in how much weight is being supported by a given wheel. Such large variations would cause undue stresses to both locomotive and rail.

In this series of photos, you’ll also see some components in fresh, glossy black paint. After months of stripping away layers of old paint and rust from the locomotive’s parts to reveal the condition of the underlying metal, seeing fresh paint being reapplied is a welcome sight!
