Greetings everybody. I hope everyone is having a happy holiday season. The following are some of the highlights as we’ve continued to stay busy through the last few months of 2021:
A pair of new Stephenson valve gear rocker boxes and rocker arms have been fabricated for a locomotive undergoing heavy overhaul in our shop. Here, the right side rocker box and rocker arm assembly is shown permanently mounted to the frame. The rocker arms were machined out of a solid piece of flame cut steel plate:

Progress on a new locomotive boiler continues, with work currently concentrated on the firebox. Here crown bars and their stays and pins are being fit to the crown sheet:

As of a couple months ago, work was completed on three brand new thermic syphons for ex-Boston & Maine #3713 undergoing restoration at Steamtown National Historic Site. These components were quite the fabrication project to design and assemble, as they required multiple processes including cold flanging on our pneumatic McCabe flanging machine, hot flanging over dies, and even repurposing our wheel press to be used as a forming press, not to mention many hours of machining to create the required dies for all this work. Despite the size and complexity, we feel the finished product turned out quite well, and these syphons can be added to a very short list of these components that have been fabricated all new in the preservation era:

We performed overhaul work on a number of running gear components for the Valley Railroad’s 2-8-0 #97, including the driving wheelsets, lead truck wheelset, and driving boxes. This overhaul work involved more replacement than it did repair, and in fact almost all components shown in this photo are brand new, including driving axles, tires, crankpins, driving boxes and crown brasses, and lead truck axle and wheels:

The manufacture of new driving boxes and crown brasses required an especially quick turnaround after receipt of order, so that the Valley could reassemble this locomotive in time to handle the large crowds for their very popular Christmas trains. The eight driving boxes and crown brasses, and associated repair and fit up work went from start to finish in about two and a half months.
We fabricated a complete set of new Type A superheater units for the New York, Susquehanna, & Western (dba Delaware River Railroad Excursions) 2-8-2 #142. Though we have a complete supply of individual superheater unit components on hand, for this job the customer elected to ship us the majority of the components that they had already purchased, and we performed all the pipe bending and final assembly work in our shop:

We fabricated four brand new narrow gauge car wheelsets for Silver Dollar City Theme Park. Shown here is our machinist Ron assembling one of the wheelsets in our wheel press:

We also made two new driving axles for one of Silver Dollar City’s locomotives. Here, a tire is being heated to reinstall on one of the driving wheel centers as part of that work:

Some smaller appliance and component jobs have also been completed:
We supplied two complete, brand new Sellers 10.5KNL non-lifting injectors, and two brand new Sellers 2” VC-style starting valves to the Nevada Northern Railroad. Shown here is one of the injectors, and two starting valves, partially assembled:

We filled an order of 275 button head rivets for the Niles Canyon Railway. These were made from code material, and the heads were forged using tooling we made in our shop:

Over the past few months we have supplied about 80 of these flip-type window latches for various customers. Here two of them are shown as an example of the finished product:

We performed a cosmetic restoration on and made a wooden base for a locomotive bell for a customer:

As the saying goes, necessity is the mother of invention (or at least reverse engineering), and overhaul work on the trucks of our Lounge Car #118 and Caboose #12 over the past year prompted us to manufacture new 4-1/4” X 8” steeple back journal bearing wedges:

Made to as-new AAR specifications, replacing worn out wedges with brand new will help minimize lateral and longitudinal play between axle and journal box, which will help the trucks track better and will minimize the potential for overheating of and accelerated wear on journal bearings. These wedges are available for purchase if anyone in the industry has a need.
As of about a month ago, we welcomed a new addition to our shop in the form of a brand new CNC slant bed lathe. A Hyundai Wai model HD3500LM with Fanuc controls, it has 35HP, 16.5” max. swing, 50” max. distance between centers, a 4” hole through spindle, and a 12 position turret – 4 positions of which feature live tooling:

With more capacity than any CNC lathe we’ve had before, and with the addition of automatic tool changes and live tooling, this machine should make short work of a range of small to medium sized jobs, and allow many components that have radially located holes, slots, keyways, ect. to be completed in one set up.
Maintenance work has continued on our own equipment, and a famous visitor as well:
After wrapping up operations on our railroad in early October, Norfolk & Western #611 is spending the winter at our facility. As such, we are happy to give our friends at the Virginia Museum of Transportation a helping hand with #611’s annual inspection. This inspection marks the 5th year interval where all non-drilled flexible staybolts must have their caps removed so that the bolts may be inspected. The locomotive is pictured here in our yard having the insulation removed from the firebox and combustion chamber area of the barrel in preparation for the flexible staybolt inspection:

#475 made a quick trip to the backshop for some work on her valves and pistons. Her valve cages and valves, and cylinders and pistons have been approaching worn out condition for a number of years. Though she had performed well enough for quite some time with her engines in this state, the wear in these components was recently becoming enough to where she was showing a noticeable increase in water consumption. We were fortunate to have a full set of new rings in stock for the pistons and valves that only required minor fitting to properly mate them with the existing components and bores. Over a two-week period these rings were fitted and installed:

Upon testing and revenue service after this repair, it was found that – though this work made a marginal improvement in performance and water consumption – it would be prudent to install new valve cages and cylinder bushings (as has been the grand plan for many years) to effect a full and complete repair. #475 will likely make another trip to the shop at some point during the first quarter of 2022 to have this work performed.
Despite appearances as presented by this picture, no, we have no plans to turn #1235 into a tender engine. However, this photo does illustrate accurately that we continue to work on both our SW-1200 #1235 and ex-CN 0-6-0 #31. #1235’s car body and #31’s tender frame were sandblasted a few months ago to prep them for any needed metal work, and ultimately paint and finishing work:

I understand #1235 will likely make her first moves under her own power at some point during the first couple months of 2022. #31…..is going to be a little while yet, but we do continue to make as much of a concerted effort on her as we can outside of manpower requirements elsewhere.
As often occurs during the winter, we are again taking advantage of the downtime our open air cars see during the colder months of the year. Here, Car #68 Hello Dolly is in the shop for an overhaul of her seats and exterior:

Our dedicated and talented team hopes you had a Merry Christmas (or other applicable holiday) and a Happy New Year! We look forward to serving you as we move into 2022!
