Of course they are. Not to worry. It will be done and running. Steamtown will have a steam locomotive operating in the near future.

I took these photos mid-September.  

This shows the firebox door being worked on.  It can be open using the lever near it's top, or air activated by pressing on the foot pedal.

Still a lot of parts to be assembled on the backhead.  A lot of plumbing to be connected, and the throttle still needs to be set in place.  The throttle box is on a pallet on the floor of the shop about a track away from the engine.

The valve boxes.  I am not certain what the yellow X means. It could still require work.

The valves are being repaired.  Work is coming along nicely with these.  
 

 
Engineers side view.  A lot has been connected but still a lot to do.  
 

 
Firemans side view.  The silver pipe above the drive wheel is for the steam line.  Coaches will be heated by her.  Don't expect high heat like we got from 2317 and 3254. 26 is a saturated steam engine, and the steam temperature is a little higher than the boiling point temp (about 360 degrees)  The bigger engines are superheated, so they get hotter, dryer steam.

The big news in the past week is that the tender is now mated with the rest of the engine.  Connections still need to be made to allow water into the boiler, of course.  Also, the pistons that were installed have been taken out.  New pistons that had been on order were picked up on Monday, October 20.  They will be machined, with rings installed and the piston rod connected so they can be attached with the rest of the running gear.

November 2014 update!

Our little engine that could is getting closer everyday to operation.
The latest dilemma that is being overcome is bending heavy gauge copper pipe to go to the injectors.  The injectors use steam to lift the water into the boiler. The old piping had kinks which prevents the steam from flowing in a straightforward manner.  The bends in the pipe were put in to allow it to connect the injector and span over the top of the beached of the firebox.

A fitting is already put on one end.  The chalk markings you see on the table helped the machinists in plotting out the curves and radii so the pipe is bent the right way and not over-bent.

Bruce is too fast for my camera.  Using that apparatus on the table, he will make the final bends in the pipe.

Test fitting the pipe over the top wrapper sheet in among other items.

And on the other side... the pipe will still need a bit of work and cut off at the end before perfectly fitting in place.

Earlier in the day, Mike O heated up the new pistons so they can fit the piston rods in to the center hole. According to Bruce on Facebook, The piston was heated to 300 degrees F with the ceramic heaters.  With a .004" press fit to the collar, (1/16" over a 3/4" per foot taper).  Heating it up that much increased the hole size .005"   They make it look so easy.  

Believe me, it was still hot.  The other piston was getting a similar treatment, but not yet mated with its piston rod.

If you can't see very well, the piston rod is hanging from the overhead crane. The white blanket is a fireproof insulation that retains the heat on the piston as it is being heated.  By the end of the work shift, both rods were keyed into their pistons.

Catching up before 2014 hits its end.  These were taken November 30.  We see 26 has a new addition, a Christmas wreath.  I did not get a chance to view the engine when the wreath was lit, but she was for a day, and then a fire was placed inside her for the first time since 1999.
 

The first piston was placed on the horizontal lathe to get channels cut, and prepared for the piston rings.  
 

Not too much to report on the valves for the moment, but here sits one of them.
 

The valve box will soon be bolted to the frame.  
 

For those of you who don't know where these parts go, they will be on the top of the cylinder area, where the wooden lid is in this photo.

The first fire led to bringing enough pressure to test the blow down valve. On December 15, they raised the pressure to about 25 psi and blew the whistle.  A short video clip of this is on Facebook.   https://www.facebook.com/video.php?v=743267379077355&set=o.81351641754&type=3&theater
 

On December 13, I took these pictures of the progress made on machining the pistons.


As you can see, this will become the left piston.
 

 
The piston and rod for the right side patiently sits in the bull pen.  
 
On December 17, after blowing the whistle, the pressure was brought up to full capacity, 180 psi, and using the water and steam, they cleared out the passages and the blowdown valve.  Getting rid of several years of dirt, dust and crud that accumulated in the rebuild process. https://www.facebook.com/video.php?v=906165449395993&set=vb.151286568217222&type=2&theater

Also on the 17th of December, Boston & Maine 3713 was moved about in the yard to get placed on shop track 5.  She had been on track 4 since 2004 or 2005. This makes her easier to spot while on a shop tour.  
Nickel Plate Road 514 took up residence on track 4, and will get more heavy repairs this winter.  
More work to be done on 26, but it looks very good that she will return to the rails under her own power in 2015.

On Thursday, February 19, the FRA hydrostatic test on 26's boiler, the last one before reassembly, took place. Everything passed with no exceptions.  This coming week, the crews wil begin adding the lagging and boiler jacketing.  Then she will move into the paint booth for her final coats of paint and lettering.  The running gear will be worked on and applied around that time.  Obviously, some parts are heavier than others, so the main rods and eccentrics may wait until she is out of the booth, and back on the floor.  They need to be buffed up to a shine again, too.  Here is what she looked like on the 18th of February.
 

 
There is still no date on her first run.  The season begins on April 18, and there is still a lot of work to do.  But looking at the posts from the past 12 or so years, she has come a long way.
I had a rare opportunity to get on the overhead crane to take these shots.
 


 
This view is inside the smokebox.  The protective cement is meant to keep cinder-cut on the smokebox floor to a minimum.  As the coal burns and breaks down, the draft of the smokestack pulls the cinders through the firetubes.  Literally, they sandblast the smokebox metal, the petticoat and other parts inside.  

 
Here is a fuller view of the smokebox.

sheesh, is all you guys ever talk about whistles?
 
Anyway, I'm looking forward to seeing Jerry Jacobson's first steam locomotive back in service in the near future, so good luck Steamtown!
 
While I'm at it, one of Jerry Jacobson's newest steam locomotives is coming along very nicely too, if anyone knows what I'm talking about.

 
Almost 10 years to the day when Timbo posted this, and we are actually getting close to his seeing Jerry's first steam engine in service.

These two photos were taken May 15.  See anything new?  

 

 
Boiler jacketing and lagging are going in place.  That is the obvious part.  But if you look under the main drive wheel, there is a newly made apparatus for setting the timing of the wheels with the pistons.  This was done in late April.  More parts going on.  More parts yet to go on.  The valves are not yet in place.

These were taken by me during Railfest 2015.  26 was expected to be ready to run, or steam or something.  Instead, her cab was opened in the loco shop, and the headlight plugged in.

 
Nearly everything in the shop was available to watch.  Machines were operating, and the ring of fire was going with the trailing wheel set from CN 3377.  A lot of things to draw your attention.

Workers on the ground and in the cab helping the visitors get access to their engine.  

 
I have no photos since then.  The engine and tender were separated for a while.  They are re-attached now.  Valve mechanisms and packing material are being installed.  Ashpan hopper work and brake work were fixed and installed.  Copper tubing for the lubricator has been installed.  A lot of work, but the only measure to the casual observer is to see the pallets full of parts a few weeks ago that needed to be installed.  Now those pallets are nearly empty.  Steam-up can't be too far off.

We made it!  Today is the day Baldwin 26 left the Locomotive shop.  I won't say "For Good," because she will return periodically for inspections and repairs.  However, she is now taking up residence at stall 20 in the Roundhouse.

 
She left the locomotive shop around 10:30 this morning, led by the blue trackmobile.  She was shoved from shop track 9 to roundhouse track 16, the "run-through" track.

From there, she was gently shoved on to the turntable.  
 

From there, we chocked the wheels so when the trackmobile left, she didn't start taking off on her own.
 

How about a little sun on your face?  
 

The trackmobile then attached to her tender for the ride back to stall 20.  
 

In to the house she goes!
 

The newest resident of the roundhouse.  a beauty from 1929.  
 

After lunch, she had a fire in her belly.  
Tomorrow, tests on the appliances.  Operations for the full 2016 season begin in April.  We shall see if she runs around town before then.

Season closing day was about 2 weeks ago. I was told she, #26, not only raised her steam but rode around here and there. Even moved DL&W F3A 664 around to a spot in the back shop, for us to work on. That was closing day. 26 was today back in here stall, maybe for the rest of the winter. I was there today with 2 others to work or 664's lighting problem, and latter 664B. We install some more of the inside lights that line the outer, inside side walls.
