A few thoughts to add to Mal's. Cement packaging long relied on barrels and cloth bags. I credit Hercules Cement with the first rail shipments in covered hoppers, in 1929. Tony Thompson has a photo of

May I have a copy of the photo, Cyril? To the list: have we lost the ability to reply directly to sender? Or am I being the e-dunce I often am? Jerry Dziedzic jdziedzic08802@...

Off the top of my head, add D&H, DL&W, L&NE, and CNJ to those who converted USRA hoppers to covered hoppers. You asked about prototypes for the Marx/Tyco car. It resembles a design that RDG developed.

A slime gon inquiry must make a first for the list! I believe you're right about the concentration process producing the slime. I think it was overflow from thickeners, with water carrying ore particl

Good article from Jack and other well-informed responses. I'll add that employee timetable special instructions often specified where crews stopped trains to turn up retainers, how many retainers to t

I'm certainly no expert on Quanah freight equipment, but Sunshine 59.7 and 59.8 model a 500-524 series car with wood ends. I built one of the kits, but it's not lettered yet. The Sunshine decals inclu

I'm not ready to buy this. Many commodities are quoted on a delivered basis, and where they are not markets would correct such price differences quickly. If a more distant producer had an equivalent q

Tim's right in saying that cement was shipped over much greater distances than some believe. Data from Susquehanna deliveries in September 1954: NYC 881907 bulk cement from E. Buffalo, NY to North Haw

Well said. Dave, thanks very much for your comments. I now have a much better understanding of the original work. (My sympathies regarding the tedium of data entry, based on my experience with much sm

I hate to rekindle a dormant debate, but I'm in favor of revisitng the Gilbert and Nelson work on general service cars. I don't challenge the methodology or the conclusions of their original work. But

I'm certain Clark and Ed are referring to the 1958 cu ft design. Can't add any other examples of evenly-spaced hatches to Ed's list without referring to my files. If we consider the 1790 cu ft design,

My, my. This is the most traffic I remember a covered hopper post ever generating. And there's lots of interesting info, from painting tips for flexible parts to the origins of Kato's SSW paint color.

I have no opinion of the Kato couplers. I'd take advantage of experience and use the couplers you're most familiar with -- Accumates. If you're the Steve Kay from NJ, L&NE would be a natural choice fo

Well, I don't think Sparrow Point or Bethlehem Car Works were involved, but that doesn't answer your question. Shortline would be happy to sell you some. I'll forward your inquiry to Tom Callan at Sho

Lou, check back issues of ELHS' "The Diamond." Jim Harr covered these cars in a recent Modeler's Workbench. Sorry I can't provide a more specific reference, but my files aren't convenient to me. Jerry

This kit models the 151352-series singled-sheathed box with 13' steel doors. Did Sunshine prepare a Prototype Data Sheet? If one was packed with mine, I seem to have misplaced it. I'm in need of photo

Andrew, I have some information on cars converted by eastern roads such as RDG, CNJ, L&NE, and DL&W. Would this be appropriate for your Columbia and East Hamlet? Jerry Dziedzic

Hi, Rich. That's interesting info about the MC cars. 1929 predates the conversions made by "eastern" roads that I researched. Do you know what service the cars were intended for? Jerry Dziedzic

How about that! I'd rather be lucky than smart. Thanks for the lead to the Corning data. Jerry Dziedzic Pattenburg, NJ <Elden.J.Gatwood@...> wrote: files Corning glass, list clearly grabbed-up dedicat

I suppose ACF's A-B car is one of the oddballs that Richard had in mind. I had forgotten about the Angus car, Dennis -- need to add that to the file. Another oddball was "Lime Car No. 3" for Columbia
