Work continues at a steady pace on Mid-Continent’s Chicago & North Western No. 1385 steam locomotive. SPEC Machine’s Steve Roudebush took some time out of his day on August 24, 2016 to show off the latest progress on the locomotive’s rebuild for this report.
The change most instantly noticeable upon walking into the shop was the shiny, like-new front truck sitting in the center of the shop floor. Like-new may not be a fully appropriate term, as considerable portions of the front truck are new. One wheel set had a goodly amount of life left in it and merely required machining to bring it into proper profile. The second wheelset had been worn quite thin and needed to be replaced with a brand new wheelset forged in Pennsylvania for the 1385. Binders, spring hangers and truck equalizers were also created new to replace heavily worn originals.
Additional work on the front truck included pouring Babbitt, lining the pedestals with bronze, and polishing pins and bushings. The front truck is fully complete and ready to be rolled under the locomotive, which is anticipated to happen sometime in September.
Above where the front truck will be rolled under, the pistons have been fully bored and the valve cages nearly completed. One of the valve cages that was found to have cracks is being replaced with a new one. The new valve cage is anticipated to be machined on SPEC’s CNC machine in the coming weeks. Work has also begun on the crosshead guides and valve gearing. After those tasks are complete, brake rigging and appliances will be next on the task list.
The two major components missing from the 1385 as it sits in the SPEC Machine shop is the cab and the boiler. To see the cab, we took a short drive to the shop of Loren Imhoff. Imhoff has graciously donated all his time spent working on the cab. Inside was a nearly complete cab. Already quite sharp looking with a bright green interior and a black exterior, another coat of paint will be added inside and out. The ceiling vent, which had proven to be a challenge due to limited available drawings, was complete and functioning. A few items remained to be completed: the ceiling needs a few boards painted and installed yet, the windows need a few hardware items remade to replace lost or broken originals, the seatboxes are not yet constructed, but all is expected to be completed by October and the cab brought to SPEC Machine so it can be made ready to mount to the frame and the roof weatherproofing material applied.
The other major component on which the 1385 Task Force has focused a great deal of attention on lately is the boiler. It has taken longer for the boiler to reach construction phase than was originally anticipated, but this was one area of the locomotive rebuild that was not to be rushed in any way. As the single most expensive component of the project, there is no room for error. Finally satisfied that the boiler design is ready for production, the 1385 Task Force has now begun gathering quotes for manufacturing of the new boiler. Once a vendor is selected and the order signed, production is expected to occur fairly quickly.
