Hydro-static test

Locomotive 924 circa 1908
Northern Pacific Railway steam locomotive 924 has been undergoing restoration in the Conservation and Restoration Center.  This 1899-built Rogers locomotive served the Northern Pacific Railway until 1924. It is a King County and City of Snoqualmie Landmark, with project support from many individuals, foundations and public agencies including 4Culture, Washington Heritage Capital Projects, the Northern Pacific Railway Historical Association, the Emery Rail Heritage Trust and more.

Fire in the 924 firebox
For the last several years a variety of project work has been underway, but the most important division of work has been on the boiler.  The boiler is where water is heated and converted to steam, usually with an oil, coal or wood fire.  The boiler must withstand high temperatures and considerable pressure.  

Locomotive 924 is filled with water, 
and then the water is lightly heated so
as to reduce the strain on the boiler 
when it is pressurized.
For the general public, a little known fact about locomotive boilers is that they must be designed to withstand four times their operating pressure.  So an operating pressure of 180 psi requires the boiler be designed to withstand 720 psi.  This is called the factor of safety, and must consider any wasting or other deterioration of the boiler that occurred since it was built.

FRA inspector Brandon King witnessed
the 924's official hydro-static test.  He
found no exceptions, which is the best
possible outcome.  This means the
inspection found that the Museum
is complying with the regulations.
After measurement, analysis and calculations demonstrate that the boiler construction is capable of withstanding 720 PSI, a non-destructive test called a hydrostatic test is performed.  This test is performed by the locomotive owner, but is witnessed by an inspector from the Federal Railroad Administration.  During the test, the boiler is filled with water, lightly heated, and pressurized to 125% of its stated operating pressure.  

Kyle I. operated the hand
pump.
It was a beautiful morning on Thursday, September 5th when Museum volunteers and staff arrived to "fire" the boiler on locomotive 924.  Recycled wood logs and waste wood were used as fuel, and the temperature was brought up to 100 degrees.  At that point, the fire was dropped and a hand pump was used to bring the pressure up to 225 psi. Visual and aural inspections were all positive - just some light weeping from a handful of rivets.  Most impressive to the Museum volunteers and staff was how tight the boiler was.  One stroke from the hand pump every 15 or so seconds was sufficient to maintain 225 psi.

Kyle and David remove the steam dome
lid and throttle to allow an internal
inspection.
Upon completion of the hydro-static test, the boiler was drained.  After this 125% test, an interior inspection of the boiler and hammer testing of the stay bolts was required.  For the interior inspection, the steam dome lid and throttle was removed so an inspector could enter and crawl along the top course of tubes.

The Northern Pacific Railway steam locomotive 924 rehabilitation and restoration project continues to progress.  The hydro-static test brought great news so now the next phase - steam plumbing - can begin.  Donor support remains critical to the ultimate success of the project; your support really makes a difference.  Please consider a making a donation on the Museum's web site: Donate Now

The Grand Tour - see it all!


The Grand Tour Package is the premier tour offered at the Northwest Railway Museum.  It is a docent-led experience that begins at the Snoqualmie Depot in historic downtown Snoqualmie. 

Your docent will give a brief tour of the Depot before you board the Snoqualmie Valley Railroad for a short ride to the Train Shed Exhibit Building. There, you will detrain and enjoy a 30 minute tour of the 25,000 sq. ft. hall that includes large and small artifacts, and several exhibits including the award-winning Wellington Remembered exhibit. 

Your docent will escort you through chapel car 5: Messenger of Peace and the 001 caboose! Next you will walk over to the Conservation and Restoration Center for a first hand look at current restoration projects, including steam locomotive 924. Both of these experiences are unique to the Grand Tour - this is the only opportunity to see inside the chapel car, and is a very rare opportunity to visit inside the Conservation and Restoration Center.

Next, you board the train again and travel west to the top of Snoqualmie Falls where you will view water cascading over the top of Snoqualmie Falls, and a beautiful view of the valley and river below the Falls. Your docent will accompany you during your trip to the Falls, interpreting the scenery and providing both historic and contemporary context. The Package ends when the train returns to Snoqualmie Depot. This round-trip experience lasts approximately 2.5 hours.

Dates and Times: Saturdays @ 12:30pm, on August 3, September 7 and 14, 2019.  Visit Shop.TrainMuseum.org to purchase your tickets in advance.

Additional dates: you may reserve a Tour on any other operating day for groups of 10-20 people by emailing the Museum

Cost: Adults $24, Seniors (62+) $20, Children* (2-12) $12, under 2 no charge. *The Tour Package is not recommended for children under the age of 5.

Back in the boiler

Steam locomotive 924 is a former Northern Pacific Railway switch engine that operated in the Seattle area from 1901 until 1924.  It is listed on the King County and City of Snoqualmie Landmark Registers, and is a property truly representative of our collective history in the settlement and development of the region.

The 924 has been undergoing a major rehabilitation and restoration inside the Museum's Conservation and Restoration Center in Snoqualmie, WA.  Despite several unanticipated setbacks in the project, it has moved forward and real progress is becoming evident.

This past week, the last major known work on the 924's boiler was performed.  Seattle Boiler Works visited the Museum to remove the portion of the throat sheet that supports the blow down valve.  A patch had been installed here with patch bolts at least 70 years ago, and the "new" material had wasted in places almost 50% of its original thickness.  So replacement was definitely warranted.

The original patch was removed, which also required three rivets in the mud ring to be cut out.  Then the affected area was cut out, and the perimeter was beveled to allow for welding.  A dye penetrant was used to check for cracks and other flaws.

Seattle Boiler Works installed a flush patch and welded a coupling for a new blow down valve.  The process involved a full penetration weld, and preheating of the native material to about 350 degrees.  Repeated passes, grinding, welding, and continual evaluation took a full day, but the results are impressive.

Up next: three replacement rivets, two new stay bolts, and more.

Thomas the Tank Engine arrives

Thomas the Tank Engine travels between heritage railways on a special truck, and on an unusually warm Wednesday, June 12 he arrived in North Bend for trans-loading to the high iron.  On hand to greet this VIE (Very Important Engine) was one of his biggest fans, Otto L.  Otto is 3 year of age, and a resident of North Bend.  He was so excited to see his hero pull up in front of the North Bend Depot.  Otto says, "Thumbs up for Thomas!"

Day Out With Thomas is an event for children 2 to 5 years of age - and sometimes for those of us much older who still LOVE Thomas.  It features a ride on a century-old train to Snoqualmie Falls, live music, a Thomas toy tent, Thomas story time, a puppet show, a bouncy house, and even a ride behind a Kalamazoo motor car!  There is also a photo opportunity with Thomas, and an opportunity to go inside the cab of a locomotive.  This is an event for all the important Thomas the Tank Engine fans in your life!

Day Out With Thomas 2019 is scheduled for July 12-14 & 19-21, 2019.  Tickets are available in the Depot Bookstore (inside the Snoqualmie Depot) daily from 10 to 5, or from TicketWeb.

Charles Baker Hydroelectric Museum wine train

This year the Northwest Railway Museum is offering two opportunities to experience a Snoqualmie Wine Train at the Snoqualmie Falls Hydroelectric Museum.  The next 3 1/2 hour experience is Saturday, May 18 beginning at 2:30 PM.

PSE Museum What's so special?  The Charles Baker Snoqualmie Wine Train features a tasting in the former carpenter shop and the Snoqualmie Falls depot. The Snoqualmie Falls Hydroelectric Museum celebrates the world's first underground hydroelectric generating station.  It was designed by Charles Baker and was completed in 1898.  Baker was the civil engineer for the Seattle, Lake Shore and Eastern Railway and recognized the potential of the falls while surveying for the railway construction.  After the railway was completed, he formed a company to build the power station, and its first customers were Seattle street railways.  Later, power from Snoqualmie Falls helped energize the Puget Sound Electric Railway and interurban car 523.

lots of friends at the depot editedAll Snoqualmie Wine Trains feature a scenic train ride through the Snoqualmie Valley along the Seattle, Lake Shore & Eastern Railway, built in 1889. Passengers ride in historic coaches, gain unique access to Museum collections and exhibits, and learn how the railroad changed everything. Wine trains include multiple tasting stops with local wine, food and music. Take home your favorite bottle(s) of wine. Each wine is available for purchase in the Snoqualmie Depot Bookstore after your excursion.

Tickets are $49 and available daily 10 AM - 5 PM in the Depot Bookstore at 38625 SE King Street in Snoqualmie or on the web through the Museum's online ticketing system.

East meets west, May 10, 1869

On May 10, 1869 a ceremonial golden spike was driven at Promontory, Utah signifying the completion of the first North American transcontinental railroad.  The Central Pacific building from Sacramento in the west met the Union Pacific building from Omaha in the east and connected the eastern railroad network with the Pacific coast for the first time in history. 150 years ago today, the east met the west and forever changed the landscape of the continent.  

In the colder latitudes, it would be another 14 years before a northern transcontinental was completed.  The Northern Pacific connected Minnesota with the Pacific coast, initially via the Columbia River, but a few years after completion, via Stampede Pass and Tacoma.  The Northern Pacific Railroad drove their last spike near Independence Creek in western Montana on August 22, 1883, and hosted a formal "golden spike" event on September 8, 1883.  At this ceremony, instead of a gold or silver spike, the very first spike driven in 1870 in the construction of the Northern Pacific was redriven by three men:  railroad President Henry Villard, former President of the United States Ulysses S Grant, and Henry C. Davis, who helped drive that spike the first time, 13 years earlier.

Like the Union Pacific and Central Pacific, the Northern Pacific had a brief but tight stranglehold on commerce in the Northwest because they had a monopoly.  Yet, just ten years later, both the Canadian Pacific Railway (to Vancouver) and the Great Northern Railway (to Everett & Seattle) had also completed transcontinentals to the Northwest.  Soon, the cost of freight and travel declined and the level of service improved.

Fast forward 150 years.  Transportation in the 21st Century is very different than the 19th Century.  Competition is generally between different modes of transportation, and the relative cost of transportation is at its lowest point in history.  Despite all the change, the original Union Pacific Railroad remains in business today, though trains no longer operate through Promentory.  Congratulations to the Union Pacific Railroad in celebration of the 150th anniversary of the driving of the golden spike!
