Michael, First of all, your photos are now approved, and members may view them at http://groups.yahoo.com/group/STMFC/photos/album/1111246025/pic/list Second of all,

Jerry, IIRC, these are merely issues of Railway Age. Every so often (quarterly? Annually?) Railway Age would designate a magazine issue as the "Freight Traffic"

I too am a mechanical engineer, and I thought I was the one who pushed Richard's button. I spend a considerable amount of time trying to get young engineers to use the specific terminology or the

Is anyone familiar with a publication, actually I think a yearly book entitled "Freight Traffic?" I have seen it occasionally on e-Bay and wonder what useful information it might contain.

Thank you for the notice. I hope that the situation resolves itself quickly. Jim   ________________________________ To: STMFC@... Sent: Friday, April 27, 2012 8:54 AM Subject: [STMFC]

John, First, full disclosure. While I am a mechanical engineer, I am not a bearing design engineer. Engineers that go into that field are making a life-time professional commitment. It is a very

I regret to inform you that effective immediately, I'm suspending all decal sales. The mechanical issues with the printer at the print house that does my printing continues to worsen making it

Dear Charles and Group, I've been reading with interest the postings about weathering lighter colored cars and, with respect to washes, wanted to share some of my experience. To begin with, I wash

Dave, I don't see how the immersion in oil could have much of affect on increased resistance. Oil is less viscous than grease at all temperatures so I don't understand how they would add

Looks like it will take some concentration on my part to stop using "friction bearings". Meant Journal bearings. Busted. Correction below Mike, I hope my latest post does not drive you beyond a six

Mike, I hope my latest post does not drive you beyond a six pack.... This seems like a good starting point for 1942. What surprised me from reviewing the car builder's cyclopedia was the immersion

Much appreciate the clarification, Richard. I confess to being one of those who has used the term incorrectly, most likely because of its general usage. Proof again that if you tell an untruth often

Tony, A fair point. My 1940 Car builders cyc is actually rather schizophrenic on this - if we want to adopt a clear naming convention based on the prototype of our era - I believe the term is "We're

Lloyd, I cannot answer your questions about how and where these cars were used but will share some information about them. I have 3 photos of these four-bay covered hopper cars. One is a Pullman

Sorry Tony, The Mechanical Engineer's definition of "journal" is that portion of the shaft that rotates within a bearing, AND the relative motion between the two is sliding. There is NO sliding

Well...what the hell...everyone else seems to have commented on some part of this subject so why not me? From The Steam Locomotive by Ralph Johnson, Chief Engineer of Baldwin Locomotive Works, 1942,

Very enlightening Dave and thanks for posting. It would seem to me that the speed at which the oil layer would establish itself would depend on how much weight was riding of the bearings. With

Dave Evans wrote: Nope. These bearings are journal bearings because they bear on the axle journals. The journal is the part of the axle that the bearings ride on. It does not matter whether

Gentlemen, If we wish to be precise, then the term solid bearing is incorrect, and in fact does not appear in engineering mechanics texts. The bearings we are discussing are "journal" bearings, and
