A milk tank car. Note the passenger type trucks and three torched off rectangles on the near end; these are the guides for the buffer springs, the buffer has been removed. These cars typically had two

Well, it is "painted on"... on the negative, that is. Dennis Storzek

Rob, There came a point after the first few decades of the twentieth century where underframe design was being driven by train buff and draft forces rather than the load the car was intended to carry.

Also a new ladder, the result of a classic "cornering" collision, I'm sure. https://www.flickr.com/photos/mit-libraries/3441330455/in/album-72157614966285159/ Dennis Storzek

I wish I could remember where I read the info I cited earlier (requirement for steel centersill and a 26' minimum body length) which I recall was imposed by the ICC, but now that I read the above list

Bruce, Can't cite the exact source, but during the twenties two regulations took effect: cabooses were required to have steel center sills, and a minimum body length of 26 feet. It is the later that d

On the Walthers automobile car kit? Yes, tack boards also. Dennis Storzek

Although, since the first consignee had to call the local agent to apply new car seals, the railroad did have some leverage... don't re-stack or block the load, and we won't seal the car, leaving cons

Tichy has .015" phosphor bronze wire, which I happen to like better than brass because it's stiffer. Here is a link to their catalog page: https://www.tichytraingroup.com/Shop/tabid/91/c/ho_wire/Defau

I don't do 3D printer work, but I do know something about designing plastic parts. I'm also familiar with "jobbing" work out to other shops. It doesn't make any difference what tolerances the Polyjet

Bill, it depends what you want to do. While the Prohet machines seem to be the only ones that have a large enough build area to do complete HO scale passenger car sides and roofs, the SLA machines, su

Thanks for the further informed discussion on the 3D printers. I have a further thought for Corey, or anyone else dealing with an SLA model: It's clear that if a prime coat will hide the diagonal laye

The real question is, when was the first retarder yard built. Until that time hump yards were "rider" yards, and there would be someone there to protest, "I'm not riding THAT thing down." I wouldn't e

Now that we have some folks with real hands-on experience in this discussion, can anyone tell me why SLA parts are oriented at an angle? Is it an attempt to change the angle of the overhangs so they d

But back in the steam era there was also the issue of tariffs on the foreign built equipment. However, I note the sign on this Grand Trunk Ry. car says the load is going via CN Ry. the Grand Trunk's n

There is still a problem with banding, very visible on the end doors of the lower two ends.. Not a problem is used for resin masters, but not ready for prime time without a lot of sanding. Cory's Utah

... Of course you can't find them because they were Utah Coal Route cars... Geesh. Link to message with pix Dennis Storzek

Thanks Tom, very informative. This proves to me that Shapeways is just maxed out and still found wanting. It's no longer an issue of resolution, but designing around the "wax tracks". It seems the SLA

Anyone notice that the wrecker used to set the car on blocking is still in the scene in the fourth photo? My best guess... the car was damaged in a wreck and the parts gathered together for shipment b
