The tank cars appear to be a mix in both shots including a UTLX car behind 120.

 

It is not clear when these cars were first used, but the NALCO name apparently arrived circa 1959 shortened from National Aluminite Company, according to Wikipedia.

Re: Earlier runs often better than late runs

dh30973
 

I’ll add my two cents to this discussion. About 13 years ago following his death, I purchased Gordon Cannon’s business of diesel detail parts, Cannon and Company, and continue to run it to date. The vast majority of the molds he created were made old school with a 2D pantograph and small precision milling machine with hand ground cutters in brass. Maybe a dozen were made by someone else for him in 7075 Aluminum by means of CNC machining. The advantage of brass is easy cutting and polishing, with the aluminum being slightly harder in both regards. The brass as Dennis noted is easily damaged by both stuck and partly ejected parts as the mold closes on the part. Repair can be sometimes be done but is tricky. The aluminum is more durable. Some of my brass molds have shot tens of thousands of parts with out any issue while others are getting long on the tooth. A lot seems to depend  on how much draft Gordon included. The ones with very little to no draft are more prone to sticking and therefore getting smashed, while others eject freely. But more draft makes parts with less fidelity, so there is a trade off. 
Apparently the tooling now being done by the big manufacturers and done in China are cut in steel by means of EDM. While those have the capability of millions of shots it is unlikely they will actually ever make that many. Our hobby does no longer support those quantities like the old days of Athearn blue box kits.

I think this would be true ONLY if the person running the molding machine had enough between their ears to know what they were doing, knows what to do when something doesn't seem "right" and knoiws for sure what not to do. having seen even good steel
tooling damaged when a macine was being run manually and soneone closed it too quickly, i.e before the just molded parts had cleared. Not good.

Re: Tri-Sorb snubbers on reefers

Jim, it was no secret, just not announced we would be gathering. The subject was the Swift reefer fleet and we were attempting to answer some questions.

 

As to the snubber, I have a photo from the Fairmont Railway Co archives that shows a Cudahy meat reefer equipped with similar rubber snubber that were being developed by Fairmont and Goodyear. A copy of this photo can be seen in page 180 in the Billboard Reefer Book published by Signature Press.

I was going to state that, but Paul beat me to it. Over the years a LOT of model railroad tooling has been "soft" tooling, because it's cheap.  The choices are, in order of increasing hardness/durability:

Kirksite (a cast zinc alloy)
Brass
Aluminum
Mold steel (a tool steel such as P-20 used in a semi hard state, soft enough to cut with conventional milling, with no further heat treatment.)
Tool steel (which is fully hardened and then worked by Electro Discharge Machining and grinding)

Kirksite could be cast over metal patterns, same as rubber molds are made. If damaged it is not repairable. 

Brass was a favorite of people who came into toolmaking from engraving. A lot of Grandt Line tooling is brass. It is difficult to repair, due to its softness and low melting temperature.

Aluminium is a favorite for CNC machining of cavities because it cuts easy and doesn't break small cutters. The old Front Range line was completely aluminum tooling. It is slightly harder than brass and more easily repaired by welding.

P-20 was a favorite of the old model car manufacturers. It is easily damaged, but weldable.

Tool steel is the gold standard, and welded repairs should be undetectable.

While there are surface treatments that can be applied to give a more wear resistant surface to most of these mold materials, the problem is, in our world, most damage is denting from closing on stuck parts rather than abrasive wear, and surface treatments are ineffective. However, for items produced with quality tooling, the millionth part should look no different from the first.

Eliminating flash by facing off the mating surfaces of a mould seems like an act of desperation to me - admittedly one which I might be tempted to do if short on funds and the tooling had not yet earned a reasonable return, but I would have my limits.  I have worked on jobs where badly worn fine-tolerance parts such as shafts that run in plain bearings (NOT 'friction' bearings, that is not an engineering term!) were restored to original size by metal spraying (a bit like welding spatter but finer) and refinishing.  Lesser wear can be restored by metal plating and polishing, but both these methods are more costly than simply skimming the mating faces in a surface grinder.
