You can get around anything with cubic dollars, including the frames and the PCB's, but even cubic dollars might not get you around the lack of a RR to run one on.  Don't expect Amtrak, a working RR with tight schedules and real world problems (like wind and weather impacting operations along the NEC this week) to fork over track time.

This subject comes up quite a bit on train buff forums, I'd bet a google search would come up with several good ones that explain it in detail.

The GG1s had an insane amount of miles on them before they got retired, they did indeed have frame issues throughout their lives, and you'd have to pretty much replace everything but the carbody to run one today. By the time you were done, the locomotive would be suffering a huge case of Theseus's paradox (think of the 'George Washington's axe' argument).

It's a shame as several GG1s were saved and a few are in 'rotting away' condition today...

Based on everything I have read about this, the closest you would probably get is a gg1-ish loco.  Something someone would have to spend a large amount of money on that may use a GG1 Body and some other parts but little else.  By possible  of course I mean the most possible scenario while still being a fantasy for the most part.

This is a very good question.  In my previous jobs, I have managed several municipal electric systems, about 32 years, but am not an electrical engineer.  Transformers and other electrical apparatus (voltage regulators, etc.) that had "transformer oil" in them, made prior to about 1975 had the PCB's in them.  During the 70's and 80's there was a liability and regulation- driven movement underway to retire old transformers with PCB's OR to pump out the oil with PCB's and replace it with new transformer oil that did not have any PCB's.

New transformers that do the same job occupy less physical space (just like motors have gotten smaller).  

I am more interested in steam power, but am kinda surprised that nobody has really tried to get a GG-1 running.  There are better welding techniques today that could repair the frame cracks, and maybe get better results.

You could start over with a brand new engine and make it in the shape of a GG-1 and that would be much better then restoring any old GG-1. The expense and then the material needed would not be cost effective in any way. The frames on most original GG-1's are beyond repair.

The main thing about the GG-1 is that they used 25 hertz(or cycles) compared to today's 60 hertz(or cycles) electricity and they had different voltage as well. So the motors would have to be changed out along with the transformers inside, making it too costly to attempt.

     Actually, the former Pennsylvania west of Sunnyside is still 25Hz (Raised to 12kv from 11), as is the former Reading in the Philly-area. The parts that were changed to 25kv 60Hz were NJT's ex-Lackawanna territory (From 3kv DC), Amtrak's ex-PRR Hell Gate Line (From 11kv 25Hz), and Metro-North's New Haven Line (Also from 11kv 25Hz). Also, Amtrak's Boston electrification was built to 25kv 60Hz.

     As PCBs go, I believe the E-60s did have their PCBs flushed and replaced.

    All this being said, I still think there's a better chance that we'll see Amtrak use the GG1 carbody design on their next new electrics than there is that we'll see a G running again.

Kelly Anderson posted:

I took a call once from a guy who wanted my opinion on his idea of filling the car body of a GG1 with car batteries and powering it that way.

From a "slightly" more practical real world direction, the most likely way to see a GG1 run again would be to dieselize it, if it would even be possible to provide power that would work with it's traction motors, if those traction motors are even restorable after all this time.  Then it could be run on any tourist line where a little more life might be squeezed out of the brittle frames, etc.  You would still be talking millions of dollars plus. 

And why would you want to?  It's not a steam engine, it looks exactly the same when moving as it does sitting dead.

Not that I think the notion of getting a GG-1 running is any more practical than those who know better (as far as I know there doesn't even exist the capability in this country to cast objects as large as the GG1's frames), how's this for a silly idea: make it a road slug, getting its power from generators in a tethered unit trailing behind. At least then you could still say it was pulling whatever was behind it

(Disclaimer: I feel the need to reiterate that I don't think any of the proposals floated are workable, and even a T-1-esque reproduction would have no place to run)

---PCJ

The PCB oil was used not only because it did not burn, but it also had outstanding heat transfer properties. There was work to find a replacement oil for the GG-1, but the best oil that could be found would result in a reduction in horsepower.  As I recall it was about a 30% reduction. The main transformer that was removed also included the tap changing equipment used to accelerate the locomotive.  This means that a replacement transformer would be complicated to build. It is too bad one of the original transformers was not saved and cleaned as it would allow a GG-1 to run today, just at reduced hp.

OK,  but only if the one that is pushing her is worthy,  I do not want to see and old beat the ^&*I of it diesel U boat pushing her around for sure. well, just saying.

This interesting subject has been all over the railroad forums of every kind as was mentioned above.  I would have to say that whomever said that building an entire new locomotive using the same outer shell design, but with new state of the art innards, had the best solution for us ever seeing one of these beauties on the rails again.

I have no idea if state of the art technology can replicate the power of the originals.  I'm sure someone smarter than I would have an opinion.

The technical reasons why a GG-1 hasn't or will not likely be restored have been been well-covered in this thread and in past ones. Another question, in my mind at least, even if the worst of the hurdles could even be overcome, is "why?". These restoration and excursion programs are hard enough to finance and to secure trackage rights to run on, without further dividing the available and potential donation and volunteer resources among increasing numbers of locomotives, just because many of them have their individual fans. Railfans seem to treat this issue like they do their basement layouts, believing that one of everything is "needed ". I even shake my head at the common insistence among some that certain O gauge models need to be made by the current manufacturers. I sometimes wonder if at least one Great Depression per generation would not be a bad thing, if for no other reason than to drive home the definition of the word need  (granted, marriage may have influenced my opinion on this issue ). Most individuals who lived through that era practiced levels of thrift throughout the rest of their lives that should be admired by subsequent generations, who are growing up in an era of excess. 

If the frames are indeed showing metal fatigue, then a simple weld fix won't quite do it.  Not knowing the metal but assuming it's cast, just welding will be difficult on it's own.  A full ultrasonic inspection of the frames would needed, which I would venture to guess means stripping one completely down.  

The one thing about steel, is when it shows fatigue, there is a underlying reason.  That would all require investigation and remediation first, if they are in repairable.

When it comes to pushing/pulling one, I would wonder what the effects on the frame would be and if there is a maximum speed.  Don't see how this would be interesting though.  Kind of like watching a tow truck pull a race car around the track.

I doubt outside of major rail-fans and northeastener's who saw these originally run that the real interest in seeing one or riding behind one would be high.  The don't have the universally recognizable style of an F or E unit diesel or the sounds and sites of a steamer.

Kind of like at air shows with WWII planes, their are many which are usually more interesting than the iconic mustang, but most crowds and interest gathers around the mustang.  I think a GG1 would be like a British Hurricane in this scenario, the plane buffs would love the Hurricane, but most others wouldn't care and still flock to the Mustang.

I am in no way bashing the GG1, although I think it's an ugly duck but very interesting as well.  It seems though like the hurdles for one operating are even greater than the T1 Trust guys are dealing with.

One without a cracked frame, etc. should be mechanically road worthy.

Maybe. However, since ALL of the GG1s had some sort of frame problems in their later years of operation, ANY of the hulks remaining would therefore NOT be "mechanically road worthy".

Correct me if I'm wrong, but I've been told, by a man who knew a Wilmington shops employee, that 4800's frame never cracked.

The GG1 on display at the Harrisburg PA RR station was moved a few months ago while work was being done at the station.

Of course it was not moved under its own power, but it is possible the frame etc is still ok or otherwise I doubt they would have rolled it back and forth.

I do not know anything else about its condition. It does look nice appearance wise.

And the one in Strasburg was moved to Washington DC a few years ago for the 100th celebration of the station.  It was moved by an Amtrak locomotive at slow speed, at night, with a number of other cars to provide braking.  

Both the WUS move and the Harrisburg move are far, far cries from banging down the NEC at 80mph with a couple of hundred tons of car behind it.

On another front, but related, I think the T-1 Trust folks busted the myth there is no one in the US who can make large castings, as they apparently found more than one company would could cast the T1 frame, which is larger than the GG-1 paired frames.  While the US doesn't have a large scale old-fashion mills, there are number of mills that specialize in low-production, complex castings that, using new technology, are quite doable.

Bottom line is where in the heck are you going to operate them?

EXACTLY!

Diesels and steam locomotives are self-contained power plants. They generate their own power on board the locomotive. The GG1 is an EXTERNALLY POWERED locomotive - it has to run UNDER WIRE! That eliminates about 99% of the track in this country.

Not only does the GG1 require EXTERNAL power, that power has to match the specs of the internal electrical components in both voltage and AC frequency. That eliminates even  more track where a GG1 can operate. SPWILLS posted, "...the former Pennsylvania west of Sunnyside is still 25Hz (Raised to 12kv from 11), as is the former Reading in the Philly-area..."  That's the only place in the country where an unmodifed GG1 could operate. That's a very limited market.

This is the only way you could realistically expect to see a GG1 "operate."

Converting one to diesel operation would be very expensive with a severely limited opportunity to generate a return on the investment. With the lingering questions about the integrity of their frames, no one is going to take that kind of risk.

The T-1 Trust castings were not myth busting. The one casting they made was fairly small.  The former LFM foundry (by what ever name they use now) in Atchinson, KS is a foundry that casts large castings today. When I was in there regularly the largest thing they cast was a valve body for the oil and gas industry. It weighted about 120,000 pounds. They had to run both their furnaces and pour from both at the same time.  Other large castings they made were axle and differential housings for Cats large mining machinery and six wheel truck frames for both EMD and GE locomotives. In most cases large castings are no longer necessary because welding technology has advanced to the point where fabrications are as good and cheeper than most large castings.

To be clear, I didn't say the one casting they made, but that the T-1 trust had found foundries who could cast the T-1 FRAME if they got to that point.  Also agree in many cases, large castings might not be needed anymore.  

Interesting side story to this, is even in the steam days, the technologies were somewhat interchangeable.  In the Pennsy Power III book, there is a photo showing the bar stock needed to weld up a new steam chest for the M-1 4-8-2, with the comment there apparently wasn't a reason to replace the cast steam chests with welded, but to keep employees employed.

Cheers,

Bob 

 

Steam locomotive frames were cast only late in their career.  For most of the time they were being built, their frames were fabricated from bar stock and so forth.  The cast frames were an improvement in that they joints didn't work apart (many were also cast with the air reservoirs cast inside, eliminating the need for external tanks).  No doubt, such frames could be fabricated by welding, but it would take a great deal of work to engineer the method so as to survive the many stresses.  CAD/CAM would help once the individual stresses are explored an understood, but that is a great deal of effort for one excursion motor.

I would edit the last few words of your post to "better than and cheaper than most large castings".  If Rudolf Diesel had choked on a sausage with his namesake engine never invented, and if Baldwin, Lima, and Alco were still building steam locomotives today, the majority of what had been cast in steel, would now be built up of welded assemblies.

Look at it this way, a Nimitz class aircraft carrier is nothing but a great big weldment, and made in America to boot.

 

Not really.  I doubt he was working in a vacuum.  If old Rudy didn't invent the diesel, someone else would've.

You could run your fantasy GG1 on any railroad you want, by powering it with a diesel genset in a disguised baggage car trailing immediately behind the locomotive.

I don't believe that would be likely.  You would need massive power to run the GG1 loco motors and then figure out how to splice into the engineer controls. There there's the question of how to supply the air for the brakes and control them through the braking lever in the loco. I guess anything can be done if you spend enough time and money to do it but the question becomes who would take on an engineering effort like this? At this point all electric locos are just museum pieces and most of them that were used on the massive electrified Milwaukee Road line were scrapped. If you enjoy traveling under the wires the Amtrak NE corridor is still fully electrified and some trolley museums still run electrics as the one at Steamtown does. 

We chatted about this on the "Steam and Preservation" forum a few months back.  PCB's, cracked frames, voltage and "where you gonna get a right of way?" were the biggest obstacles identified.  Even if you use some kind of power car instead of line voltage you're still talking WAY beyond the reach of most museums or restoration societies to accomplish without a serious pile of cash.

I would guess it would cost in excess of two million dollars to put a GG-1 back in service. That would in a commercial shop, no volunteer labor.  The only place I could see it running might be between Philadelphia and Harrisburg. If there were money available, the place to start is with Antrak to see if they were willing to host its operation.  Then talk to GE in Erie and see if they would support the engineering effort.  The only thing harder on a locomotive that running its wheels off is letting it sit out in the elements without moving for many years.   Restoring a GG-1 to service would be a big task.

A South Shore 800-class (same as Milwaukee Road 'Little Joe' electrics) still operates on occasion at the Illinois Railway Museum (IRM). it won't run like it did on the South Shore as IRM uses 600 volts DC while South Shore was 1,500 volts DC. Yes, it was modified to operate at the reduced voltage available at IRM.

 

I'm curious about just what "modifications" were done to the "Little Joe" in order for it to operate at the reduced voltage of 600 volts DC.

When the Joe arrived at IRM, they were able to test run it without modifications on 600VDC back and forth in front of the depot.  The wire hangers there were totally above the wire so the pans wouldn't snag on them.

Rusty

Couldn't tell you.  It's been about 20 years, since I was active at the old chooch farm and I spent most of my time in the Steam Department.  But, I was active when both the Joe and GG1 arrived.

I can guess that IRM's been replacing the hangers to allow for pan operation on the main, but I don't know the progress.  I know for a while, they would have to drop the pan and coast when going under the wire frogs.  Might still have to, I don't think there's a wire frog that would allow for pan and pole operation.

Rusty

When changing a high voltage DC car or motor  to run on 600 volt DC usually requires dealing with the air compressor and lights and control.  In some cases IRM has been able to just change the compressor armatures from 1500 volt to 600 volt armatures. Lights and control were frequently designed to run on 600 volts, since this was already a standard, and uses a motor/generator or dynamotor to change the 1500 volts to 600 volts. In this case the lights and control circuits are just disconnected from the MG and reconnected directly to trolley. Later equipment ran lights and control on a lower voltage, usually in conjunction with batteries. In this case a replacement MG may be required.   In a dual voltage car the traction motors and accelerating resistors would also be reconnected when the voltage was changed, but in museum service this is not necessary. 

The PCB problem was solved by removing the transformers and flushing the locomotive.

The only way a GG1 will run again is if a group organizes, selects a candidate for restoration, has it inspected, finds someone who can do the necessary mechanical repairs, find someone who can engineer contemporary electronics to fit inside the carbody, find someone to intstall said electronics, test, retest, more inspections, find someplace to run it...

... AND gather the funds to do all of the above.

Easy-peasy, right?

The fate of the gg1 has been sealed. You will never see one running under its own power and seeing one being pushed would be a sad event.

Go to a museum and look how they are, they were a magnificent machine for their time.

I saw many gg1's in their day running up and down the mainline of the Philly area under the majestic catenary of the mighty Pennsylvania railroad. 

I would love to see a gg1 run again but only as they were not something risen from the dead like a Frankenstein monster. 

Rip GG1, the greatest electric locomotive ever. 

My dad used to see the GG1's on the PC in New Brunswick while he was still a firefighter. In the PC days he had the unfortunate task of helping supervise the clean up's of the bodies of jumpers from the train station. History aside, a GG1 will more than likely never run again. Costs combined with the fact of where to run it. Amtrak would be most likely unwilling to run one. The only way I can see it happening is putting new electronics into a GG1 body. Picture taking a postwar GG1 shell and putting it over a new chassis with new electronics. There's a better chance of the T1 being built than a GG1 ever operating again.

Yes, sadly jumpers is a word that I use for suicide jumpers. It was very unfortunate. People occasionally jumped from the concrete bridge over the Raritan River but most of the incidents were on the tracks.

It'd take only two things to make a G run again.

Lots of money and lots of connections. 

If someone like a Warren Buffet or Bill Gates fantasized about a GG1 running as a kid there would be a GG1 running.

Probably not a perfect analogy since it's a relatively common diesel to an electric but it wasn't just 20 years or so that no one outside of the city of Philadelphia knew who Bennett Levin was... a little known head of a Philadelphia city agency who was apparently a train buff and just happened upon some rail-connected property in the Juniata section of the city.    Well he had enough money and connections to not only acquire E units and other PRR equipment but to have them restored AND to run them on mainline trips on class I railroads.   Yep, it's "only" an E unit but it's still no small feat for a private individual to not only get it up and running and inspected and insured for service but to convince a  class I railroad to let it run.

What if a Bill Gates or a Warren Buffett wanted a symbol for their start-up privately held electric passenger railroad and they just decided to acquire a G and rebuild it to the standards necessary to operate under todays FRA standards.   And what if they just happened to be using the same voltage/frequency as AMTRAK/the NEC?

Farfetched, but just think if someone else with deep pockets and a love for a classic status symbol decided they had to have one as their flagship locomotive and rebuilt it for the (near) triple digit speeds it was capable of.

The Milwaukee Road used 3000 VDC (later 3300 VDC) in the overhead wire to power their locomotives.   However, converted a 3000 VDC locomotive to run on 1500 VDC would probably not be a big problem. One issue in making this change is that for any given horse power, a 3000 volt locomotive will draw half as much current as a 1500 volt locomotive.  Therefore, all the wire and contactors will not handle twice the current required when the voltage is cut in half. Most locomotives that are converted like this would end up with half the horsepower.
