Turntable Update

Just a quick update from our Project Manager, Tom Falicon on the turntable in Bryson City!

Ties have been installed on the deck of the turntable bridge. The longer ties support walkways so the crews can walk past the engine while it is on the turntable.

This month both the precast concrete inspection pit and the precast concrete bridge for the rail passing over the nearby creek will be installed.

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!

Updates

The guys at the steam shop have been hard at it, as usual. A good majority of the work has been focused on trying to prep and clean for the coming work. Tim and Marshal have been inside the Tender working on the removal of the old layers of epoxy with a needle scaler. In some places the epoxy can be at least a quarter of an inch thick.

Brian has focused on scaling the cylinder and valve body cover, cleaning it up and removing rust.

Joe has been working with the engine lathe making boiler studs and mud rings.

A few various spare parts have been brought into the shop to be lapped and cleaned. Focusing on the blower, Marshal was able to diagram the plan for its rebuild.

The guys were sporting their new Full Steam Ahead t-shirts! Looks like they are pretty proud of them! These brand new shirts hit our merchandise shelves last week and are hot sellers. If you can’t physically make it to our GSMR retail store you can order yours by calling 828-488-5200.

The turntable project is moving along nicely as well. Here is a report from the Project Manager, Tom Falicon:

The contract excavating crew has been working tirelessly and flawlessly to excavate the site. The father and son team are perfectionists and are really producing some fantastic attention to detail work! The approximate depth of the bottom of the turntable pit has been reached. All that is left is to excavate deeper for the outer ring wall and center pivot foundations and structures.

The east slope of the site has been reduced so it will be easier for observers to walk up to the turntable observation area.
An access road has been cleared that will serve as the main access for the steam engine tool/service truck. The road will allow the service vehicles to pull right up alongside the inspection pit with tools and supplies for the servicing of #1702. Silt/mud fencing has been installed around each mountain of dirt and in other key areas. With last week’s rain there were no signs of muddy run-off.

Deep excavation for the concrete structures is well underway and the 19 piles have been cut to their proper height. The re-bar for the center pivot area was delivered last week and the outer ring wall re-bar steel is in Asheville and ready to be delivered as soon as it is needed. The Steel forms for both concrete pours are expected to arrive within the first weeks of May.

Breaking Ground!

As reported in the previous blog post, the turntable installation has begun! On Monday, April 6, the ground was prepped for pile driving to begin the following days. These piles will serve impart as the underground support for the 89,000lb turntable.  Pile DriverA pile driving crane was brought in from Savannah, GA to drive steel beams deep into the earth at the site. For roughly two days Bryson City, was treated to the loud echos of colliding steel as a result of driving the 50ft long piles anywhere from 15 to 35 feet into the ground. An engineer from Charlotte, NC was on hand assisting by attaching sensors to each pile so that data could be recorded and signal when the pile had been driven to refusal. A total of 19 piles were installed and secured. Scroll to the bottom for a short video of the pile drive!

With the piles in place the area is now undergoing an excavation of roughly 10ft down into site. This space will allow room for forms that will be used to lay the concrete into exact shapes that the space needs for further support of the structure. The dig was put on hold due to the massive amount of rain the area saw last week. Before the concrete will be laid, the exposed ends of the piles will be cut off and final grading of the pit will be preformed to the exact depth.

Spring Progress

The steam shop guys have been busy this month and couldn’t be happier about the warmer/milder weather that has finally reached the Smokey Mountains.

The tender has been moved inside the shop and the cleaning has begun. Tim, one of our GSMR Operations crew members, has been recruited to help with Tender duties. He has been removing the old epoxy that has been inside the tender for several years along with prepping for the new marine grade epoxy that will be applied.

This past week Brian and Marshal have been pulling the studs off the firebox and wrapper sheet. The old rivets were shot out a few weeks ago! Stay tuned, there may be video footage of the rivet removal coming!

Joe has been working on the engine lathe making new rivet snaps. They are ready for heat treatment and then the next step of re-reviting the mud ring.

The remainder of the old firebox sheet has been removed and the mud ring inside was welded and grounded down.

Great news! The crack check was completed on the wrapper sheet and everything passed. There were a few minor repairs that the developer revealed when it was applied to the penetrant (the pink dye).
