Steam & Excursion > AFT 1 by Tom ArnoldDate: 02/05/24 07:32 AFT 1 by Tom Arnold Author: bandob Photo by the late Tom Arnold. Tom was a prolific photographer in the 70's and 80's, and he graciously allowed me to copy many of his photos. Here's AFT 1 in Baltimore in 1975. Note the slumbercoach in the second photo.

I went through the American Freedom Train in Anaheim for my 12Th birthday It made a lasting impression on me. There is a book available by Warren Motts from his time on the AFT https://mottsmilitarymuseuminc.com/gift-shop Kevin Date: 02/05/24 08:31 Re: AFT 1 by Tom Arnold Author: co614 Yes, those are photos of our test run from Baltimore to Hagerstown to see if the engine was capable of entering service 2 days later and pulling the AFT throughout the greater NE. Yes, it was truly a 30 day miracle that the late Bill Benson and his crew of 49 paid professionals plus an Army of about 200 volunteers pulled off transforiming an engine that had sat in a junk yard for years into a runner in 29 nights and 30 days.
Great memories. Thanks, Ross Rowland P. S. The book mentioned above is VERY well done and worth having by anyone interested in the AFT project. It contains hundreds of never befor published photos that do a great job telling the story of the trains 21 month journey through all 48 states. Edited 1 time(s).

Very Nice Years earlier, Bill Benson, owner of 2102 --- at that time, wanted a evaluation of the 2 stored locos, at Streigle's used loco yard, in Baltimore, Md. and asked me to make an evaluation of their condition. He arranged for Streigle's to allow my access to the engines and to conduct a summary estimation of their suitability, in 1971. My report for Benson summarized my estimation of the two T-1 class locos, numbers 2100 & 2101, as eminently operable, and that #2101 had been given Class 5 overhaul at Reading Loco Erecting shops in 1957 or '58, and never placed 'in service' ----- in RR lingo, it was known as a 'zero mileage' engine. So, it made sense for AFT to use the 2101, to haul the American Freedom Train through the narrow RR clearances of Eastern USA, where a larger loco would be prohibited from operating. Booster-equipped, T-1s are a very strong locomotives, and very suited to the task of pulling the AFT. The restoration crew did a marvelous job in getting 2101 restored to operation. Loco #1 ( 2101) now is in the B&O Museum, Baltimore, MD. Sister 2100, is undergoing a 1472-day boiler inspection and re-certification at Cleveland, Ohio. Soon to be restored to operation, the work is progressing at a very fast pace, with a large component of volunteers doing a lot of the work alongside experienced professionals. It's good to see young folks so intimately involved in the whole restoration process...they're learning so much, as the boiler and parts are inspected, repaired and re-applied to 2100! I financially contribute to the 2100's restoration costs; but, it takes many hundreds of donors in order to complete the rigorous demands of restoration. Please join me in financially supporting the 2100 effort, by sending a generous, tax deductible contribution to the organization. Funds are sorely needed as reassembly nears completion ---- and costs rise significantly, approaching steam-up days. Engine 2124 is in the Steamtown Collection at Scranton, Pa, on public display. W.

They never ran on Amtrak as steam heat/DC cars, but were immediately placed in line at Beech Grove shops for conversion to all-electric Heritage Fleet Slumbercoaches.

Thanks. John in White Marsh, Maryland Date: 02/06/24 13:16 Re: AFT 1 by Tom Arnold Author: wcamp1472 I'd bet that the subject has come up, but that the Powers That Be vetoed
the initiative. The Hennesy lubricators on the first T-1 locos do a fine job --- --- as long as the driver set does NOT get derailed, and the lubricator does not get crushed between the axle and the lower frame binder-bar. Hennesys that cause trouble are those where folks have cobbled-together an improvised repair ---- rarely successful. Back in the day, the repair was to get a new lubricator off the stockroom shelf, and scrap the damaged lubricators. Also, Hennesys has lube-pads made of pourous material to promote oil convection and distribution.... but, the lube pad could be damaged if overheated during events like break-in runs, etc. So, as long as they're well maintained, Hennesys are reliable --- and were an acceptable substitute for roller bearings. It was the War Production Board that restricted roller bearing use on other-than war time purposes. Apparently in the case of the smaller axles on the T-1s, rollers were allowed to be specified. T-1s built after WW2 were all equipped with roller bearing axles. Interestingly, the wartime, new NKP Berks were allowed to be built using rollers on their driver axles, and on the 2-wheel lead truck. Plain bearings on trailer truck and tender trucks. Go Figure! W.

Cost saving manuver on the simpler bearings (tender and trailing truck). The rollers on the lead truck do a better job of taking the lateral punishment, as apposed to plain bearings. It would be an interesting read to go through any correspondence notes convincing the use use of rollers on the drivers, instead of plain bearings. Especially when you consider the Pere Marquette's bershires were built in the same facility and received plain bearings, instead of rollers. Date: 02/06/24 15:30 Re: AFT 1 by Tom Arnold Author: wcamp1472 The difference with plain and rollers on the driver axles is how
the lateral thrusts ( side-to-side) are handled. With plain bearings the load on the axle is well handled by the oil film and the cylindrical surfaces on the load bearing elements. The lateral, side-to-side, thrusts , like when navigating curved trackage, are distributed over the inner hubs of the driver centers. It is a large diameter, flat disc that bears against a flat, brass, semicircular mating surface, which is part of the crown brass and journal box. The brass face of the journal box's mating surface is called the hub liner. By necessity it only covers the top 180-dergees of the driver hub. There are many schemes to keep that area lubricated, all of them have drawbacks and limitations. Suffice it to say that the hubs and liners always presented maintenance challenges. Hubs and hub liners are designed to be intermittently loaded, not in continuous contact. Timken's tapered roller bearings do a superior job of transferring lateral thrusts from the axle to the journal box. The challenge is that the rollers and cones/cups are tapered --- thus, one set of rollers can only handle the rolling cones are restrictive in only an axial load that forces the cones tighter together. An axial load that forces the rollers in the other direction, move away from the tapered races... So, the Timkens are used back-to-back. in pairs, whether in automotive axles, or locomotive applications. So, in locomotive use, there are two-piece steel castings that span the distance between the drivers, hub-to-hub. And a pair of facing rollers, at each end of the axle. So, in drivers, you are free from having to maintain worn driver hubs. Drivers on roller bearings are the highest desired driver besrings . Rollers on the pilot truck axles are vitally important, too. The pilot truck guides, and leads tne rigid loco frames through curves and complex track configurations. So, sets of Timkens are vital when used on pilot truck axles. Always a good idea. W. Not proofed, yet.... Edited 1 time(s). Last edit at 02/07/24 17:33 by wcamp1472. Date: 02/06/24 15:43 Re: AFT 1 by Tom Arnold Author: wcamp1472 The Pete Marquette locos might have specified plain bearings,
when ordering the locos, as a cost issue. I'm sure Timkens were probably double the cost of comparable plain bearings. However, many RRs appreciated the "zero-maimtenace" arrangement of Timkens, over the the more expensive, high labor-costs of plain bearing maintenance, continuously needed ....grease blocks,etc... W. Date: 02/06/24 16:51 Re: AFT 1 by Tom Arnold Author: co614 I can tell you that after years of struggling with the Hennessey's under the 2101 ( 1975-77) and constantly "fixing" them to the extreme pleasure of working with the 100% Timken equipped 614 it is difficult to express in words the difference. Let's put it this way...............I would do EVERYTHING possible to never again have to operate a mainline plain bearing engine.
Ross Rowland Date: 02/06/24 18:05 Re: AFT 1 by Tom Arnold Author: wcamp1472 In my humble opinion, the perfection of the Timken tapered
roller bearings, and arrangement for reliable wheel bearings is the most significant invention of the 20th century.. World-wide, every wheeled vehicle built after about 1935, has been built using Timkens tapered roller bearings. Billions of bearing-sets, are and have been inside everything from aircraft landing gears, to escalators, elevators, air conditioners, autos, trucks, tanks, Army, Navy and Air Force.... if it rolls on wheels, there's going to be the Timken, tapered roller bearings, They may be off-patent, by now. But, even competitor's bearings owe their origins to Timken's superior originals. When, in 1968, Ross's High Iron Company rolled NKP 759 into the hollow roundhouse at Conneaut, Ohio, Timken sent a field engineer to inspect 759's axle rollers. He said that he wanted to inspect the bearings before we moved the engine and put it back in service! He was astounded when I told him we had just towed the engine 600 miles, from Vermont ! After recovering from that news, he had us remove the end cap from a pilot-truck axle, as well as several bottom plugs, under the main axles---- In each of the grease samples that we examined, the 1958 applied grease, was still pristine and 'new', nice, new white grease ---- as if stored in a sealed shipping container. The Timken engineer instructed us to apply about 16 ounces of new grease, into all the plug holes, seal up the plugs, add seal-wires at each plug. "Once sealed, DO NOT EVER REMOVE THE FILL PLUGS, AGAIN!"... was the instructions from Timken's field rep. We exchanged business cards... And he left. 759's plugs are still in place. Obviously, the engineer knew that over-zealous "tinker-ers" would be a greater threat to the bearings, than a lifetime of excursions. The danger is always that possible dirt and grit contamination would endanger the bearings so, he wanted their bearings fully protected. So, to the best of my knowledge, 759's bearings and grease are still pristine, and undisturbed as it reposes in Scranton, remembering the Halcyon Days, of over 70 trips, under Ross's able leadership. Thank you, Ross, for allowing me to have an unforgettable chapter in my most unbelievable LIFE, so far. 759 taught me SO MUCH!, including about roller bearings.. W. Edited 2 time(s).
