Day of Caring 2013


Each September, United Way of King County organizes Day of Caring, an event where thousands of volunteers take the day off from work and volunteer in their communities.  United Way asks non-profit organizations to sponsor projects, and group leaders from the supporting businesses select projects and organize volunteers.  This year, on September 20, 2013, the Northwest Railway Museum participated in Day of Caring by sponsoring a series of projects. 

This year there were a variety of projects at the Railway History Center to help preserve and share railway history.  Teams of volunteers set up more than 1,200 cubic feet of new collection shelving, moved a substantial number of additional shelving pieces, planted native plants and gardened around the Train Shed, worked on window screens and seats for the Spokane, Portland and Seattle coach 218, prepared windows for painting on coach 272, did a thorough cleaning of the Chapel Car, and generally had a fun time of helping care for the Museum.  A total of 35 volunteers from Microsoft participated, and they were assisted by several regular Museum volunteers who helped coordinate the event.


The Northwest Railway Museum thanks all of the volunteers from Microsoft and the Northwest Railway Museum.  It was a very successful day that allowed projects to be completed in one day that would have otherwise taken months to complete.  If you have a group that would like to volunteer for a day, please contact Volunteer Coordinator Cristy Lake.  Volunteering as a group for the day can be a fun way to serve the community and have an enjoyable time with friends and coworkers too.

Copper for a coach roof

Individual copper sheets were attached
with a folded seam and soldered.
Most early 20th Century railroad coaches had canvas roofs.  Some railroads specified that the entire roof be clad with canvas while others preferred copper cladding on the car ends. Copper was not an afterthought but an option specified when the cars were built.  Oxidation and the limitation of black and white photography often make it difficult to identify this in the 1912-era photos, but the Museum is confident that coach 218 was built with copper hoods. 

Completed lower hood.  One improve-
ment over 1912 materials is the use of
marine calking to seal edges.
Certainly one of coach 218's distinguishing features is this copper cladding on the roof ends, but unfortunately the original surviving copper was brittle and riddled with perforations.  So restoring these to their "as built" appearance and condition has been one of the project priorities. These "hoods" feature compound curves and are areas where it is more difficult to keep out rain water on this design of railroad car.  The copper cladding improves durability and reduces long term maintenance. (Some years ago, Spike had an opportunity to work on two Canadian Pacific Railway passenger cars that featured full canvas roofs and can attest to the fact that the canvas fails first on the compound curve at the ends of the cars.)

Bob M. attached the last of the clere-
story cladding to allow the final piece
of copper to be attached.
The design of the hoods is simple but the tin smith skills to install it are no longer common.  Fortunately, Gary J. is a highly accomplished marine carpenter and this work was an easy adaptation for him.  To begin, copper sheets were cut into small rectangular sections that would conform to the roof curve.  The edges were bent up or over to allow a folded seam with the adjacent roof panels.  All the seams were tapped flat and then soldered to provide a watertight seal.  The final product mimics the original roof but the appearance of the soldered seam is slightly different, probably because of the difference in performance between an internally and externally heated soldering iron.

Completed copper hoods debuted dur-
ing Railroad Days 2013.
Work continues on coach 218 but completion of the copper hoods allowed its use during Railroad Days 2013 where it carried an estimated 120 additional passengers.  Work is being funded with the generous support of 4Culture, the Nysether Family Foundation, proceeds from GiveBIG 2013, the Snoqualmie Tribe, and individual contributions from people just like you!

Smoke or heat?

A critical responsibility of every museum is the general protection of the Collection.  Broadly defined, that could mean protecting it from everything, which is unrealistic.   However, prudent steps can be taken to protect the collection from things that could reasonably occur.  Examples may include exposure to bright sunlight, rapid changes in heat or humidity, small to moderate earthquakes, and fire.

Inside the Northwest Railway Museum's new Train Shed exhibit building, some of the most important and representative objects in the Collection are protected with UV-filtering windows, R-30  insulation, a structure designed to the most modern seismic code, and a fire detection and suppression system.  Yet no system is perfect and unfortunately the Museum has had a variety of issues with the fire detection system. 

Local codes required smoke detectors in the original construction because, as Spike has been advised, they often detect a fire sooner than a heat sensor.  However, in a building with fans running all the time and nearly 750,000 cubic feet of air, there have been problems with these sensors.  Since completion in 2010, the Train Shed has experienced as many as 50 false alarms.  Fortunately, the Snoqualmie Fire Department has been very understanding and supportive, and several fire fighters now know almost as much about the Collection as some of the regular docents.  However a problem like this cannot be allowed to continue. Aside from the story about The Boy Who Cried Wolf, what if the fire department is responding to a false alarm when your house is on fire?

The Museum and its contractor partners have worked hard to determine the cause of the false alarms from the smoke detectors.  The Train Shed is not particularly dusty - in fact a lot cleaner than the Conservation and Restoration Center, which also has a number of smoke detectors.  There are no sudden changes in temperature that could cause condensation to form inside the detectors. The model of sensor does not have a history of issues.  There has even been consideration as to whether an infestation of insects or spiders is causing the problem. However, without being able to pinpoint an exact cause, it has been determined that smoke detectors are not reliable inside the Train Shed, and the local municipality approved a change. 

Early in August 2013, E Squared Systems was on site to replace the smoke detectors with heat sensors. This is quite a feat in a structure filled with artifacts, with ceilings as high as 35 feet, and not a lot of floor space to operate a 14,000-pound lift.  Now the Museum looks forward to improved reliability, and the Snoqualmie Fire Department looks forward to fewer late night museum visits.

Keeping track safe and reliable

The grade immediate below the track
structure is called the subgrade.  It was
disturbed by an excavator during a
recent construction project conducted
adjacent to the track.
Good track is easy to take for granted, but a safe and reliable railroad depends on it.  And good track requires a stable subgrade, especially within the 1:1 live load zone beneath the track.  (The 1:1 live load zone is the area that extends downward from the ends of the ties at a 45 degree angle.)  Steep slopes, poor soils, seasonal flooding, adjacent uses, earth quakes, and heavy annual precipitation are all among the conditions that must be considered to ensure stability.  So when recent construction activities were found to have affected the subgrade at Snoqualmie Falls, immediate steps were taken to protect the track and trains. 

A rock slope was constructed to stabil-
ize and strengthen the subgrade for
more than 200 linear feet.  Geotextile
fabric was placed below the rocks to
improve performance of saturated soils.
First, for trains already operating, speed was immediately reduced to a crawl to reduce dynamic forces on the track and subgrade.  Second, a licensed geotechnical engineer was called in to inspect the subgrade below the track and determine if and under what conditions trains could continue to operate.  Third, rehabilitation work was performed to mitigate the issues discovered in the affected area using a design that was reviewed by other engineering professionals.

Falls.
The long term rehabilitation plan was developed by the Museum's geotechnical engineering consultant at PanGEO Inc and reviewed by other knowledgeable professionals including Museum volunteer Dave H., who is a civil engineer - thanks Dave!

The design uses "heavy loose rock," which are large rocks 30 inches and more across.  It relies in part on prior stabilization work performed when soil anchors were driven under the track and a retaining wall was installed at the toe of the slope.  To address the current issue, the slope on the subgrade below the track was covered with geotextile fabric and the heavy loose rocks were keyed into the sloped using an excavator.  This design places several hundred tons of rock on the subgrade slope and restores integrity to the 1:1 zone beneath the track.  However work did not stop there.  Areas affected by construction activities that were outside the 1:1 zone but within the 2:1 slope of the railway grade are being strengthened with a foot or more of quarry spalls three to six inches in diameter.

Work took three days to perform and was completed between scheduled trains.  What is most impressive to Spike is that the total elapsed time between discovering the issue and implementing final rehabilitation was just four days!  Trains are continuing to operate and will resume track speed when authorities determine that stability has been fully restored.  So a stable subgrade once again supports good track.

A day of firsts

Coach 218 pauses outside the Train Shed prior to being switched onto the train.
The first passengers since the 1940s and the first five-coach train since 1988!  On July 13, 2013, coach 218 was marshaled into the passenger train in Snoqualmie creating the Museum's first five-coach passenger train since 1988.  Coach 218 then carried its first revenue passengers since the 1940s! 

218 prepares to depart for Snoqualmie
Falls with 30 passengers, its first
revenue run since the late 1940s.
Coach 218 first entered service in August 1912 for the Spokane, Portland and Seattle Railway.  By 1948 it had been replaced by more modern cars and relegated to work train service where it served as rolling accommodation for railway workers.  It was purchased at auction by Museum supporters in the early 1980s and stored.  In 2007 the Museum made the decision to rehabilitate the car and work began soon after.  The primarily volunteer-led effort completed much of the carbody work and beginning in March 2013 several grants have funded two full time carpenters to continue work on the car, but with continued substantial volunteer support.  Support from 4Culture, The Snoqualmie Tribe, the Nysether Family Foundation, proceeds from GiveBIG! 2013, and other private funders is helping advance this important project.


Temporary "parlor" seating is in the
coach 218 to allow Day Out With
Thomas visitors to ride inside.  An on
board docent explains the state of the
project and a diagram shows the name
and function of all the exposed wooden
parts.
A project of coach 218's complexity always involves a few surprises.  On July 1 the Museum learned that the paint supplier "lost" the formula for the deep coach green paint that had been accurately matched from original samples.  To move the project forward, the car has been temporarily painted with a similar color created from one part jet black and five parts jade green.  The correct color will be matched and applied later this summer.

After years of effort, 218's carbody rehabilitation was substantially completed earlier this month.  Considerable effort remains to complete the interior appointments and lower window sashes, but with a visit from railroad royalty (Thomas the Tank Engine) it was difficult to resist the opportunity to "try out" the 218!  And after Thomas departs for his next museum venue, coach 218 will return to the Conservation and Restoration Center where work will resume on the interior.

Thomas the Tank Engine arrives!

Thomas the Tank Engine has returned  to the Snoqualmie Valley for Day Out With Thomas 2013!  The really useful engine arrived at the North Bend depot today for a visit from the Island of Sodor.  He will be visiting with young children and their families in Snoqualmie on July 12 - 14 and 19 - 21, 2013.  Tickets are $21 and are available via the link or phone number here.  You may also purchase tickets in person (and avoid service fees) at the Snoqualmie Depot, 38625 SE King Street, Snoqualmie daily from 10 AM - 5 PM.
 
Day Out With Thomas is a fun-filled event for young children and their families.  Admission includes a ride on a train with Thomas the Tank Engine, but also a variety of activities including a bouncy house, story time, a puppet theatre, motor car rides, locomotive cab tours, model trains including live steam, temporary tattoos, and live music by Eric Ode, Nancy Stewart, and Brian Vogan and his good buddies.  Check out the accompanying video images from one of our recent Day Out With Thomas events (this year will be similar, but even better!) and see what you have been missing!  Why not join the fun this year?

Winning the lottery?


 
Well, sort of. Two new lottery commercials were filmed in Snoqualmie, and one of them featured a locomotive from the Northwest Railway Museum's Collection.  So for several local businesses, a church and the Museum it was sort of like winning a small prize in the lottery.

A film crew sets up the interior shot of
"Jim" operating his locomotive.
The Museum hosted the Washington State Lottery and their film production partners on a recent warm and sunny day.  (Those days have not been plentiful this year, but that is another story.)  

The commercial filmed at the Museum features "Jim," a character who wins the lottery and upgrades his HO scale locomotive to a full size model.  Of course the real locomotive happens to be the Museum's locomotive 201, a model RSD-4 built by the American Locomotive Company in 1951 for Kennecott Copper.  This 1,600 HP locomotive is similar to the once ubiquitous ALCO road switchers that operated on more than a dozen railroads in the Northwest.  The bright orange behemoth was pulled by one of the Museum's Baldwin RS4TC locomotives, which was "removed" from the film in post production.  An actor sat in the engineer's seat pretending to operate it.  A home and garage were also added in during the post production process.
Locomotive 4012 pushed and pulled
the 201 but was rendered invisible
during post production.

Thanks go out to the many Museum volunteers that met or exceeded the client's expectations and made it all come together for a clever and amusing ad.

The commercial is now running on local television; watch for it!
