KCRA 3 in Sacramento aired a story about the Sierra #3 on Wednesday evening. You can see it for yourself (note: Reporter Walt Gray refers to being able to see it at Jamestown next month. Shop tours resume on the 11th of November, but we don’t expect to be operational until April!)

Oversized loads require a special transportation permit, issued by The California Department of Transportation (CalTrans). Our load is over the height limit. A permit had been obtained for a 14’6″ load (at the top of the steam dome). Our final measurement (including rail, angle of the trailer, etc), measured 15′ 3″. This required a new permit. The request was submitted first thing in the morning, and at this point, we are waiting for our permitted route from CalTrans. The permitted route will take into account the height of overpasses, overhanging wires, and any other known obstacles which may interfere with safe travel. We anticipate the need for a pilot car on 120 in Tuolumne County. Brendan Siminuci, of Siminuci Construction, has volunteered to provide pilot car services for that portion of the trip.
Jim Bays and Mark Johnston take last measure of the high point of the load for the permit.

All loaded up, and ready to hit the road!
On Thursday, October 29th, the #3 will be shipped back to Railtown. Consisting of the new boiler, the chassis and the driving wheels, it doesn’t quite look like a locomotive. . . yet. To ensure the ship date is met, it’s all hands on deck, and a long week ahead. Here’s a look at what could be seen in the shop today.
Al DiPaolo and George Sapp adjust the rigging for the final lift of the boiler, while the documentary film crew looks on.
Lisa Smithson and Don Shapiro scrape the bearing surfaces of the driving boxes in preparation for the final fit.
Don Shapiro applies machinist's blue dye to the axles of the driving wheels for testing of the driving boxes.
Lisa Smithson operates the crane while Leonard Jones rocks the box back and forth over the dye-covered axle. An examination of the stained bearing surface indicates what still needs to be scraped and the process is repeated until the surface is perfectly married.
With the boiler on the ground for the final time, Dennis "DJ" Ponder grinds down the proud rivets, while being documented by the film crew.
Al DiPaolo and Leonard Jones adjust the mag drill for reaming the furnace bearer strap holes into the frame. One of the last items needed prior to the permanent attachment of the boiler.
Phil Hard and DJ Ponder adjust a mag drill to ream holes for the running board studs.
George Sapp cuts stock for bolts at the end of the day, foreshadowing Monday's activities.
The brasses provide the bearing surface for the rods where they fit to the crankpins. As with the driving boxes, they provide a sacrificial material which bears the stress of the force on the driving wheels. Each rod bearing is comprised of two halves which are fitted over the crank pin.

Cracked rod brass needs to be replaced.
As a bearing surface, the rod brasses need to be re-machined and replaced with regular use (like the tires, or brake shoes on your car need to be routinely replaced). After assessment, the decision was made to replace all of the rod brasses during restoration. Models were constructed and shipped to a foundry in the San Jose area for casting. The new brasses are being machined, first to fit the outer dimensions, then finally, for the interior dimensions.

Sporting a fresh coat of black paint, the three sets of driving wheels left Railtown this morning, enroute to Sacramento one last time. Along with the driving boxes, they’ll be installed on the chassis for the return trip, tentatively scheduled for October 29th.
