In the shadow of the COVID-19 pandemic and its resulting shutdowns over the past few months, we have been fortunate SPEC Machine has been able to work on the Chicago & North Western #1385 at all. Many of the things done during this time period has been measuring, fitting and design work that provides little to no visual change to the locomotive which makes progress reporting a bit more difficult.
That said, the boiler and smoke box have been positioned which allows for the furnace bearers to be made. The boiler is fixed solidly to the smokebox and cylinders but like so many other things, steel expands as it gets hotter. When the 1385 is fired up it will start at ambient temperature but when it reaches a full head of steam of 200 PSI the boiler will be about 388° F. This will cause the boiler to grow in length.
To accommodate this, the rest of the boiler and the front corners of the firebox rest on a pair of bronze shoes called furnace bearers. The shoes bolt to tabs welded to the front-bottom of the mudring. These shoes allow the boiler to freely expand and contract as needed while still being supported by the locomotive frame.
The below photos show the tab as well as the top part of the shoe holder that will support the weight of the boiler.
On the fundraising front, the 1385 project was recently the recipient of a $7,000 donation from the Bluewater Michigan Chapter of the National Railway Historical Society. While this is good news for the 1385, it sadly was donated as part of the Chapter’s dissolution and distribution of assets. The Bluewater Chapter was established in 1982 and was well known in railroad circles for operating many successful mainline passenger excursions around the Midwest, helping to bring railroading to the public. The Chapter faced tough times in recent years as mainline excursions became more challenging to operate for a variety of reasons, ultimately leading the group to dissolve the Chapter last year. We salute the Bluewater Chapter members for their amazing work over the years and are appreciative of this final act of generosity toward Mid-Continent’s 1385 program.
