I think we've beaten the AI topic to death, so I've changed the subject line. First a word about how the decision was made as to which boxcars to build... Lane goes into this in his seminal work on

Sure. Written when most railroad CMOs still believed in double sheathing, and at the dawn of the time when nearly everyone changed their mind. And NP, of course, was a late holdout on this topic,

First of all, what does a real railroad think of Single Sheathed vs Double Sheathed, read the attachments. And please note the date of the letter is right in the USRA era. At this point I'll

Dave, Without getting too much into the weeds, the short answer is that Greenville Steel Co. (GSC) built four series of 70-ton flat cars in 1951-1953 including C&O 81000-81249 built to the same basic

lol - bingo ! and hopefully self driving cars won't be 'user programmable' :-D I wonder if ChapGPT knows timetable & train orders? could it be a trainmaster/dispatcher?

I don’t have the answer but I have been working on a 3d model for the 70 ton car and so I can make a few guesses about the 50 ton version. The center sill of the 70ton car is built up

However it won't do one thing to motivate someone to model or pick up a paint brush. I would argue technology has created more problems in the hobby by running off modelers due to

ChatGPT is a proof-of-concept system, it a commercial or public offering on which anyone can rely, and the developers never have said otherwise. It’s a demo to gauge interest … of which there is

This is indeed sad. Joe was a great railroader, modeler and a wealth of information on SAL/SCL passenger equipment. He will be sorely missed. Jax, FL

Meaningful work to whom? I’m sure the negotiation and lawsuits on reimbursement and value were meaningful to someone after control was returned to railroads by USRA. Not meaningful to modelers?

Bruce, looking at the full resolution image of the broadside builders photo looks like the floor thickness just above the bolsters is thinner than the rest of the car, but it still looks like it is

Dave, While I do not know if it applies to these cars, 70 ton flat cars usually had their decks "inset" so that the steel of the bolster was showing. As an example, see the attached photo of a Rapido

Back in the 2016-2018 time frame I went tank car crazy. I built a number of resin tank cars, purchased castings from Tom Madden, and built cars swapping tank and bodies and cutting them up. Then
