The Pressure’s On!

 

Our last blog post featured a few videos of the flue tube instillation and we are happy to report that the boiler is ready for water and pressure (hydro static testing)! A huge step in our final months of completion before our scheduled return of #1702 this summer!

Since the completion the guys have been using compressed (120lbs per square inch) air to test the pressure inside the boiler. Steam Services of America contractor Bob, explained that by using soap and water they can easily locate where the leaks are allowing the air to escape, causing suds to appear. Once identified the leaks will be sealed. The next step is the hydro test which should be conducted sometime this week. After the test is completed a few minor additional items that the boiler needs can be installed and the boiler can be prepped for initial fire-up testing.

Last week Brian worked to complete the fabrication of the water column that will gauge the water level in the boiler.

The engine was moved so that they could prepare to reposition the tender behind the engine. While preforming the first movement test they discovered a few needed repairs to the entrance track of the steam shop.  Those will be repaired before the next move.

While #1702 was outside the guys enjoyed giving it a much needed wash!

_MG_0898You can certainly see a change in the firebox interior with the instillation of the tubes and flues and now the transverse arch tubes. These transverse arch tubes are the newest addition. Originally arch tubes were inside the firebox but this new transverse design will prove to be more efficient in circulating the water from the side sheets to the top crown sheet allowing the water to be heated faster and more efficiently.

Steam Services of America also delivered the 30 New Sets Super Heater Units in March. The SH Units will be installed once the hydrostatic testing of the boiler is finished and the boiler is being prepped for fire-up. The SH Units which are installed in the smoke box and lay inside the flues inside the barrel of the boiler take the saturated steam generated in the boiler and reheat the steam through the SH Unit piping from the gases from the firebox which travel trough the super heater flues heating the steam inside the SH Units. The saturated steam is about 450 degrees Fahrenheit when taken out of the boiler and heated to approximately 650 degrees Fahrenheit after passing through the SH Units. Once the steam is superheated it then enters into the valves and pistons where the steam goes to work moving the engine drive wheels.

Our anticipation is growing with the excitement of finally seeing #1702 back on the line! We hope that you have booked your ticket. If not, find all the information HERE.

 

 

Flue Tubes!

More progress to report as our steam shop guys and Steam Services of America official contractors; work hard at the final stages of restoration. The flue tubes of the boiler are being installed. We have exclusive video from the shop of the installs courtesy of our shop guys. Enjoy!

The Final Staybolt!

Exciting news from the steam shop! After months and months of work the FINAL STAYBOLT was completed! The last of the 1,175 staybolt was finished this past Tuesday and the guys were certainly excited to check that task off the list!

Here are some videos courtesy of Brian and Marshall.

There has been great progress with the tender. The inside has been cleaned and prepped for paint. The air and steam gauges have been sent off to be calibrated, and it will be prepped for a new wheel set. Pressure testing was completed and it passed with no leaks!

Say hello to Tony and Eli! These guys have been working on the compressor. It has been stripped and the cylinders have been honed. They are checking the gauges in the compressor to make sure they are still round. The valves have been measure determined the clearances.

 

 

The tubes and flues were delivered from Germany. Next expected to be delivered are the ferrules, which are the copper rings that are placed around the tubes and flues to seal.

Buddy has begun working on the cab carpentry. New beadboard will be replaced throughout the interior. The exterior has received some deserved attention. A lot of the rough patches and holes are being filled in, welded or bonded over to create a new fresh and smooth surface.

 

 

Our last exciting arrivals are the builder plates! These are casts of the original plates, and will be one of the final pieces placed on the engine before it’s set to return to the rails!

Happy 2016!

Happy New Year! We are back after a bit of break in blogging. Trust us, the work has still continued! With the anticipation of our 2016 Summer Steam Engine return, the shop has been working harder than ever getting 1702 ready!

Over the last 2-months the focus has been the staybolt work. Almost all the rigid staybolts have been completed and the guys are waiting on the delivery of the flexible staybolts so they can finish up.

You can really see the difference!

Needle scaling the tender is all but completed. As of yesterday a few of the shop guys were cleaning out the last bit of old epoxy. The fuel tank has been pumped to remove the old oil. In the coming weeks two of the wheels on the tender will be replaced and there are a few spots on in the inside that will need to be patched!

A few months ago the boiler was tested and a few low spots were revealed. Those have been repaired. The boiler tubes are also making there way to the shop within the coming days.

An exciting new addition in the steam shop – the 1702 cab! It was moved inside a few weeks ago so its repairs could begin. It will need to be cleaned, patched and repainted – plus a few more minor repairs to make it ready to occupy again!

We hope you all had a great holiday! Thanks for following along on this journey with us. We are getting closer and closer to the summer debut – we hope you’ll join us!

Riveting Day!

Finally after months of anticipation, riveting day finally arrived!

We were able to get some great video footage of the riveting process. Enjoy the videos below!

Steam Shop Tour Success!

A great big thank you to all who joined us for the Steam Shop Tour during RailFest weekend! It was such a great success, with many out of state guests joining us along with locals, whose excitement was only fueled by the chance to see the progress.

  

#1702 was on full display along with, the steam shop, #777 diesel engine, and if you notice, a small replica engine that we repainted and displayed just in time! This little green guy will be placed in Bryson City beside our historic depot and will be a great photo op!

Here are a few fantastic captures of the engine. Photographer Charles Hardin was kind enough to share these great images. Enjoy!

The shop guys were happy to host everyone for the afternoon, and really enthused by all the questions everyone had. After a nice holiday weekend they were back at it! The biggest project has been fitting the interior sheets in the boiler. All but one sheet has been placed inside and the contractors have been working to get them set. A door sheet had to be removed so it could be realigned.

    

New bolts for the steam pipe on both sides have been installed!

Joe has been working on the lathe making some much needed tools. All the belly brace bolts are completed, and he just finished up on a new welding fixture for the flexible staybolt sleeves.

August & Upcoming Steam Shop Tour!

Steam Shop Tour got your attention? Keep reading for a special announcement!

Steady progress continues at the shop this month! The new door sheet has been returned from its heat treatment. It is ready to be sandblasted and installed. The flu sheet has also been heat treated and is now waiting be polished and sandblasted. Work continues with the stay bolt holes on the top wrapper sheet as well.

The ultra sound thickness test was conducted on the boiler shell and everything was in tolerance! Another step forward!

The guys took on a tedious 2 day project with one of the water glass valves that needed to be re threaded. Thanks to Marshal for the before and after photos showing the valve in the process of being tig welded below:

We are really excited for the upcoming RailFest 2015 celebration. Although the #1702 won’t be ready for its debut we will be prepping for an exclusive STEAM SHOP TOUR! So if you have enjoyed following the blog, now is your chance to see all the progress in person! Find all the details HERE.  Better book fast! There will be a limited number of seats available and it is limited to ages 12 and up only. We look forward to seeing you in September!

Here is the latest from the Project Manager Tom Falicon on the Bryson City turntable :

The turntable concrete is COMPLETE! 

As usual, the work was tough but both the Swain County and the GSMR crews were up to the task. Next step is to back-fill the outer ring wall as well as install the inspection pit and the storm water runoff system. After the surrounding earth has been cut down to actual grade, Concrete aprons will be poured around the inspection pit as well as the outer circumference of the turntable.

We’re planning on a 150 ton and a 90 ton crane being brought in towards the middle of August to do the job. The turntable was primed and painted, and it’s now ready for it’s trip across the parking lot and into the pit.

The two cranes required for the task are scheduled for Monday August 31st to make the parking lot move and Tuesday September 1st for the setting of the table into the pit. In the mean time, back-filling and compacting of the outer pit wall will continue and a bulldozer will be brought in to lower the earth to the proper grade and also make things more presentable for our Railfest 2015 Celebration!

Early June Update

We’ve got a short update for this week! Most of the work has been centered on drilling the new staybolt holes. As of Tuesday they had drilled well over 1000 holes.

 

 

The new piece of the throat sheet was returned with the 8-degree bend needed and the holes for the flexible staybolts have been drilled.

Marshall has been working on readying the section where the new throat sheet piece will be placed.

  

Welcome Robert Franzen!

After several months of deliberation, we are happy to announce that Robert Franzen, owner of Steam Services of America, has been selected as the official contractor for the boiler rebuild of #1702.  Robert FranzenFranzen is also currently working on a steam engine rebuild, similar to that of #1702, in Alaska. During the boiler rebuild he will be joining the team a few days a week in the shop, as he is going between two projects.

The first order of Franzen’s work began this week as Bob Gold, was brought in to aid the placement of the new stay bolt holes. Original layouts of #1702 are being used as the reference point to which the new holes will be placed. Marshall has been cleaning the dirt and removing the pink die used in the crack tests. He has also spray painted the surface with a temporary gray in order for the fresh marks to be visible when applied. A few reference markings have already determined that on both sides the blowout valve will be moved from its former position to allow the boiler wash to operate more easily than before.

 
A section of the outer throat sheet that revealed cracks earlier, was removed and a new sheet has been cut (roughly 3 quarters of an inch steel). The piece has now been sent off so that a special 8 degree bend could be formed to allow the fit to be exact. In order for the guys to get a good handle on the section that was cut, they removed the air tank which opened up plenty of room for access. In the air tanks absence the guys constructed a brace to support the boiler so that it wouldn’t sag.

 
Brian finished up his dirty job of removing the cylinder valve covers and the insulation was cleaned out. The cylinders themselves need more work, but they have been cleaned as much as possible for the time being.

Here is the latest from Project Manager, Tom Falicon, on the turntable project in Bryson City:
A pivotal point was passed in the turntable build this week by completing the building of the forms and re-bar and then successfully pouring 47 cubic yards of concrete for the first quarter of the lower ring wall. The force of 47-yards of concrete pushing against the forms and bulkheads was tremendous, but everything held tight and the pour was a complete success.
In order for the concrete to cure slowly and properly, we must wait five days before the forms can be removed. To aid the concrete in hardening properly, we assembled a watering system using a pump in the nearby creek and a series of garden hoses. Water is continuously flowing over a blanket of burlap keeping the concrete from drying out, overheating and curing too quickly.

 
We have already begun assembling the re-bar for the second 1/4 of lower ring wall pour and we will also start assembling the forms for the upper ring wall pour on the first 1/4.
Another monumental mark was reached in the past weeks, when the large bearing assembly that the turntable pivots on was set and secured! The installation of this pivot bearing means that the center pivot pedestal build is complete and able to support the entire weight of the turntable and any locomotive placed on it. The bearing assembly install could not have gone any better!

Springing Forward!

The last few weeks have been very productive at the steam shop! The guys have really made great progress in the tender; it’s been a pretty nasty job removing the years’ worth of epoxy. So far they estimate to be about 2/3 of the way done with the needle scale removal. New drain pipes were installed finally replacing the dated ones that were rusted and not holding water.

 

Test patch bolts have been threaded into the mud ring. The testing revealed a few minor modifications need to happen before the rest are installed. The outer throat sheet will also eventually need to be removed due to the cracks that were revealed on the interior side of the sheet. Those will be repaired before installment.

 

Brian has continued his needle scaling work on the cylinder covers. He has also begun to try and clean out the old insulation underneath the cover. Presently the covers are stuck in place and he is working to loosen them so they can be removed and all the insulation can be replaced.

  

The turret parts as well as the boiler check valves have been taken apart and readied to be hand lapped and cleaned.The steam dome cover has also been set aside. That won’t be placed on the engine until the final stages.The old brake shoes have also been removed and those will be replaced.

 

Using the diagram that was drawn last week, Marshal and Brian have constructed the new blower piece.

 
The oilers have been drained and the oil lines are being purged with air to clean them out. The guys will begin to identify the lines that need repairing and those that will need to be replaced. Joe was nice enough to showcase the old oil that they are glad to see removed.

 

The engine was moved a few feet in order to access an area behind the wheel for cleaning. Below is a short video! 

Here is the latest turn table update from Project Manager, Tom Falicon-

All primary excavation has been completed and all 19 over length steel I-beam piles were felled like tall hardwood trees and then stacked neatly in the parking lot.

Concrete sub-footers were poured for both the ring wall and the center pivot. These sub-footers will provide a flat, solid work area to erect the concrete forms as well as provide a solid surface to secure them to in order for them to be able to handle to excessive force of poured concrete.

30,000 lbs of steel concrete forms for the entire project arrived from Charlotte early last week.

The storm water drainage system and piping for the center of the pit was installed and capped off just outside the poured sub-footer of the ring wall. The build of the re-bar cage for the center pivot started last week followed by the forming. The concrete pour for the center pivot will be completed soon.

The large steel plate that the turntable bearing attaches to had holes machined in it too large by the supplier so four reducer spacers were machined and welded them in place. The dead center of project has been identified and clearly marked. The plate will have to be painted before installation to help prevent future corrosion.

The underground water intrusion from the river and the creek has been challenging to deal with; water is constantly streaming into the pits. A gravel sump system has been built to help keep the pits relatively dry.

The project is moving along in an extremely timely manner! Great job by the crew working to get it done!
