Happened to be in Chattanooga on Saturday afternoon, and decided to stop by the Grand Junction depot of the Tennessee Valley Railroad. 630 was heading up a short train of about seven nicely painted passsenger cars with a power car mid-consist. Watched her back up on the wye tail track onto the NS main with two old friends, Jim Wrinn (editor, TRAINS) and Dave Marshall (former TVRM employee/volunteer).

When the train started up the main heading towards downtown Chattanooga, she was working some steam up the grade in GRAND fashion!

Needless to say, there were an abundance of video and still cameras recording the action!

It was certainly good to see an old "friend" completely restored and running with excellent valve timing!

Would not be surprised if one of Jim's photos makes the cover of a forthcoming issue of TRAINS! Wink

Also got the "skinny" on the NEW NS steam program:

It will NOT be anything like the former Southern and NS programs, but will rather emulate the UP's steam program with trips sponsored for SHIPPERS and CUSTOMERS of the railroad, plus local dignitaries and politicians.

There will be a FEW public trips, but the trains will be relatively short due to the size of the motive power: 630 now, and 4501 later next year.

NS CEO Wick Moorman recognizes the VALUE of steam PR, but he is NOT a Graham or Robert Claytor, both of whom had steam in their blood, in addition to being effective railroad executives.

I applaud the program even with the stated limitations. ANY steam is better than NO steam.

There are definitely NO plans for 611 to run again. In fact, I overhead some "high level" gossip that when an organization such as TVRM develops in Roanoke, then, and ONLY then, will management consider returning 611 to the NS main.

NS has NO steam rebuilding facility on their property.

And that's a good thing, it may last a long time with those limitations. I've had
a chance to see some of the early videos, 630 appears to be very well done. On top of having a well timed chuff, she has a nice sounding whistle.

Had the pleasure of firing 630 and 4501 back in the bi-centennial year trips when they both were working out of Alexandria.

Does my ol' heart good to see 630 at it again, and looking forward to seeing the big brother. I don't expect to do any more firing, though . . . Big Grin

Sorry to say that the 630 has been having axle/crown brass overheating "issues' since she was tested/operated on NS main line trackage. After at least 3 runs, she still has over heating "issues" with her main drive axles.

Just my opinions but, grease block lubricated plain bearings, in today's main line railroad environment, are/will be a continuing problem. Witness the Canadian Pacific Hudson, which has had drive axle overheating "issues" ever since she was restored and returned to CP main line service. The CP Hudson is now "out of service" in order to convert the plain bearing, grease lubricated crown brasses, to babbitted, pressure feed oil lubricated, axle bearings.

The Texaco High Tex 8 block grease is no longer available, and the subsitute block grease is acceptable for lubricating plain bearing side rod bearings, but doesn't seem to withstand the higher temperatures involved with brass crown bearings on drive axles. Maybe the axle surface finish is not smooth enough (ten micro-inch finish), but I'm more inclined to think it is the quality of the block grease and the steel cage that forces the grease block against the bottom of the axle.

At any rate, in my opinion, the 630 and the 4501 should be up-graded to Babbitted, oil lubricated crown bearings.

1) The question of why they didn't convert the 630 to babbitted bearings and pressure feed oil lubrication is a very good one. You need to ask the folks at the TVRM THAT question!

2) Both UP 844 and 3985 are roller bearing on all axles. Only the Southern Pacific RR used babbitted crown bearings with pressure feed oil lubrication, since they developed that concept in the U.S.A. and even patented that process (thus the SP never went with roller bearings on all axles, except for the two GS-5 locomotives).

3) There has obviously been no market for Texaco High Tex 8, since the 1960s. Even large paper rolling mills no longer require that product. The equivlent to High Tex 8, currently available from a block grease manufacturer in New York State, works just fine for those tourist railroad steam locomotives, still on grease blocks. However, those tourist line locomotives apparently do NOT see the speeds that #630 will see on NS main line trackage.

CHATTANOOGA, Tenn. – In the same city where Southern Railway dropped the fires of its last regular-service steam locomotive in 1953, Norfolk Southern today returned to the ranks of the Class I railroads with its own steam program. Chattanooga is also where Southern Railway’s beloved steam excursion train program began in 1966; it would continue operations until 1994.

Now, the re-creation of history is repeating itself.

Tennessee Valley Railroad Museum’s newly restored 1904 Alco 2-8-0, Southern Railway No. 630, pulled a VIP special today from NS’s DeButts Yard to the museum’s Grand Junction station to kick off NS’s “21st Century Steam” program. The museum, which is celebrating its 50th anniversary this weekend, will run public trips on the NS main line on the same route twice daily, Saturday and Sunday.

Friday’s trip included two coaches and a diner, left about 11 a.m., and returned about 2 hours later after a 12-mile round trip that included a visit to the wye on TVRM tracks. Passengers included railroad officials and shippers.

On Thursday night, NS CEO Wick Moorman described his vision for the new steam program, which will be similar to Union Pacific’s and focus on employees, shippers, key decision-makers, and the public. He said the train will operate about 1,800 miles in 2012, with No. 630 pulling six cars that NS is refurbishing at its Altoona, Pa., shop: five coaches and a power car. They're former commuter cars from the Connecticut Department of Transportation. Moorman said the passenger cars had excellent trucks, and that the shop is performing extensive body work. The final route for the 2012 tour has not been set.

The railroad needs to do everything it can to raise public awareness about the good activities that it does, Moorman said. The new steam program is a part of that effort. Moorman posed in the cab, but left the throttle to the NS crew.

“Isn’t it always a great day for a train ride?” asked Mark Manion, NS’s vice president of operations, just before 630 whistled off at the DeButts diesel shop. Shop workers came out of the building to watch the train pass.

Answering questions from the audience on Thursday night, Moorman addressed interest in seeing Norfolk & Western Class J 4-8-4 No. 611 return to the main line again. He said that when the Virginia Museum of Transportation has a steam restoration program like TVRM’s, then NS will consider operating the engine. No. 611 was part of the NS excursion program from 1982 to 1994, pulling the last trip in December 1994 from Birmingham, Ala., to Chattanooga, and return.

Coincidentally, it was a trip to reach a Labor Day Weekend excursion in Richmond, Va., in 1966 that started in Chattanooga that kicked off Southern’s popular steam excursions with Southern 2-8-2 No. 4501. That engine, which celebrates its centennial this year, is in the midst of a major overhaul for the
new steam program. On Thursday, shop crews unloaded new boiler tubes and stored them in the Soule Shops at TVRM’s East Chattanooga shop complex. No completion date has been set for the 4501.

No. 630 debuted earlier this year after a 13-year overhaul. The engine has been running on the museum tracks, and also made two test runs on NS earlier this summer to Cleveland, Tenn., roughly a 50-mile round trip. Bearings on the left side under axles 1 and 4 ran hot, but those problems seem to have been solved. The museum’s shop forces continue to fine-tune the engine’s performance for longer trips over the main line.

In addition to UP, Canadian Pacific has its own steam program. BNSF allows infrequent steam operations. Neither CSX nor Canadian National allow steam operations on their lines.

Back in the mid-80's we wanted to order some of the Texaco High Tech 8 for the 765. We called Texaco to place the order, only to be told that they don't make it any more. Part of the reason was the lack of demand, and part of it was due to the formula for this particular grease. The Texaco folks told us it was a very dangerous production process and that there were several stages during the process where the grease was very volatile. Because of reduced demand, they were not willing to take that risk any longer. When we told them our predicament, they agreed to give us the formula! They suggested that a smaller company might produce a batch for us.

We did indeed find a smaller outfit that agreed to produce a batch of High Tech 8 for us, using the Texaco formula. We agreed to purchase the entire batch. When we went to pick up the order (almost a box-car full) the owner of the company told us that we had better make it last because he would not make it again. He also alluded to the fact that it was a very dangerous process and had he known the dangers ahead of time he would never have agreed to make it in the first place.

So, there's your answer as to why there is no more Texaco High Tech 8.

I'm guessing this is why 4449 went through the trouble of converting to roller bearing?

You may be a bit confused concerning what I posted above about block grease and roller bearings.

First, since the Southern Pacific RR developed/patented the babbitted crown brass with pressure feed oil lubrication, they saw no need to purchase steam locomotives with roller bearings on all axles. Only two GS class 4-8-4s where purchased by SP with roller bearings on all axles (GS-5 numbers 4458 & 4459). Thus, GS-4 #4449 is STILL equipped with the babbitted crown brass and pressure feed oil lubricated bearings on all four drive wheel axles. However, the engine truck, trailing truck, tender trucks, and auxilary tender trucks have ALL been up-graded to modern cartridge type roller bearings.

Second, the sodium soap based block grease is still manufactured by Battenfeld Grease Co. in New York State & Canada. It is only produced in minimum quantity "batches" of at least 1800 to 2200 pounds, and as Rich stated above it is quite dangerous to produce. This substitute "block grease" has been working for more than 20 years as side rod bearing "pin dope", or "pin grease". The Friends of SP4449 have been pressing this product into round sticks, rolled in powdered graphite, for 4449, the UP steam program, AT&SF 3751, and anybody elso who wants to purchase cases of "ready to use" rod/pin grease.

Third, except for the main drive wheel axle/crown brass grease lubrication system on those steam locomotives so equipped, all the "other" plain bearings are simply oil lubricated journal boxes, very similar to the old freight car trucks of many years ago. Thus, the block grease is NOT used in those types of bearings.
quote:
One question I have is, is the oil lost, or are there seals and a recovery system
on them?

There are oil cellers below each driving box. Originally, those steel cellers had spring pad lubricators in them, consisting of a steel spring scissor type device that kept the woven cotton lubricator pad in contact with the bottom of the axle journal. That woven cotton pad had dozens and dozens of cotton string tentacles, that hung down into the journal oil. Thus, the crown bearings received their oil pressure from lube lines fed directly from the "machine oil" mechanical lubricator. The "excess" oil from the pressure feeds simply ran down the axle journals, and into the steel spring pad oil cellers, which maintained THEIR oil level. Some small amount of journal oil is always lost to ground via the seals, just the same as those plain bearing freight car journals of the "old days".

We no longer use those old steel cellers & spring pad lubricators, due to wear and cracked celler housings. We now have aircraft aluminum welded cellers with very large/thick cotton sponge pads, which make full contact with the bottoms of eack axle journal. The mechanical lubricator plunger pistons are also cranked to their wide open position. Now a days, oil/grease is MUCH less expensive than bearings!!!
Art,

Aside from the cost, the real issue would be finding a machine shop large enough to remachine the locomotive frame so that the driving box areas could be enlarged in order to accept the big roller bearing "cannon housings" and corrisponding jaw liners installed. In the good old days, the frame was generally mounted up-side-down, and the driving box jaws re-machined. Obviously the cab/boiler, etc. had all been removed.

It would be much more cost affective to convert the 630 & 4501 to babbitted crown bearings and pressure feed oil lubrication. I believe that is what they are doing to the Canadian Pacific 4-6-4 #2816 now.
I believe 630 was down to it's frame at one point, and if they wanted to do roller bearings that would have been the time to do it. At this point i'm sure its a little late in the game.
Did 610 get any love this weekend or did she remain stuffed away in the back?
I have a feeling TVRM is running a bit behind, I think the plan was to 4501 running by now, otherwise I don't think 126 would have brought in. But this is not a knock, they have done a great job, and no one can prevent shortfalls and delays and troubles and such. Did 6133 generate any excitement about getting their own 6914 done?
I have known TVRM President Tim Andrews since he was a college student, and I have run both 630 and 722 as a summer employee in 1984. We actually did some double-heading that Fall. I have been a supporter of TVRM since 1974, back in the days of Paul Merriman, Bob Soule and John Bennett.

Although I am glad to see 630, and presumably 4501, refurbished, I still question whether or not 611 would have been a better choice:

ONE powerful and modern engine with roller bearings EVERYWHERE!

Also an iconic and impressive locomotive to non-railfans alike!

Yeah, it would have cost a little more, but they would have had an EASY-to-maintain engine with a stoker, and many other modern appliances. Wink

I believe TVRM shop forces, plus some contracted labor, could have restored the 611.
Given the "limited" nature of the current NS steam program, rebuilding the 611 probably doesn't make much economic sense in any case. And even if VMT or the city of Roanoke were to 'foot the bill', it's still a question of return on investment. This isn't the steam program of the "old days" where they ran every weekend and anyone could buy a ticket. This is a limited-basis, mostly non-public program. They don't "need" an engine like 611 for that, especially right now.
NS would have deadheaded the engine to Chattanooga, switched it up the "belt line" to the museum, and footed the bill for the restoration.

There would have been NO cost to the city of Roanoke or the VMT.

The boiler and flue tubes would be the most costly aspects of the rebuild, and some contract labor would be needed.

Maybe one million, but then they would have had one SUPER loco to show off their railroad! Wink

That is putting it mildly, Unseenthings. Hindsight is ALWAYS 20/20. Plus, when 630, or even 4501, was/where "down to their frames", was LONG before NS even thought about a "steam program". The 630 was NEVER expected to be operating at 40MPH on the NS main lines, back in those days.

If 611 ever returns to service her rebuild will not happen at TVRM for many reasons. The Belt Line would never handle 611 without a major rebuild. The downtown wye coming off the mainline is way too tight on the radius and rebuilding the track, three to four miles, would run into the millions.

Bringing the engine in off of the Jersey switch of course is easier, however you then face Missionary Ridge Tunnel which is not even close to accommodating the 'J'.



Lastly, the Soule Shops facility is undersized in multiple areas to handle an engine of this size.

A much better bet would be for an independent contractor to rent space somewhere such as at the old N&W East End Shops in Roanoke and have at it right there. Freight Car America is already doing such with part of the facility as it is.

Just wanted to update this thread for future reference. After Railfest, 630 came up lame again on a return trip from Knoxville, and sat out the 2011 Polar express season.

As we had debated  above about oil bearings, we now have a a recent quote from Mark at TVRM in March 2012

"The #4 axle has been converted to the Southern Pacific spring pad lubricator design oil cellar.  Proof tests will be perfomed soon.  Following the conclusion of the testing, the remainder will be converted.  The decision to change from grease to oil cellar lubrication was made after determining that today's varities of block grease are not suitable for operation above 25 mph.  Yes, we tried them all."
