I had Shapeways run two more parts with much finer detail and/or more complexity than the bolster pan reported previously. But first, this note - I know these are not freight car parts, but the STMFC is where the most intelligent discussion of Shapeways' processes is taking place. Also, I fear that if I take this to the Passenger Car List the discussion will focus on the parts and not on the process. Thanks for your forbearance.
Tom's recent round of test projects prompted me to send my L-2 passenger car triple valve out again...

Tom and I seem to be taking opposite tacks on this... Tom is looking to learn the limitations, so as to be able to design usable parts/patterns within those limitations. I think with Shapeways, he's found that build orientation is important, and if you can connive to have them use your preferred orientation, you can get usable flat parts. The problem is, there's lots of ways to get flat parts, photo etching, for one, and photo etching brings the added advantage of doing some creative folding to produce 3-D objects. Of course, Shapeways can be considerably cheaper than etching, especially for one-off parts.

I, on the other hand, want to test the usefulness of the process as a sort of "universal modeling medium" to produce those needed parts that just can't be made easily by any process... that's essentially why they aren't made. My triple valve fits this description; it's small, no, downright tiny, has almost no flat surfaces, and has mechanical features in multiple orientations, which would preclude simple injection molding even if I wanted to cut a simple cavity. This is not a simple part, but it shares these restraints with a variety of hardware parts; door hardware, hand brake housings, truck journals and spring packages... all the little details, many of which we would like to combine with a larger object, such as the door hardware integral with the door, or carside.

Anyway, here's a link to a set of photos of the project to this point; a photo of the prototype, some screen shots of my solid model, and photos of the part I had printed a couple years ago, and now from Shapeways.

http://www.flickr.com/photos/25967611@N04/sets/72157623125645997/

This result is better than last time, to the point where I'll probably use them if nothing better comes along before I get back to the project they're intended for. I'm not happy with the surface, but have seen enough dirt caked underbody equipment to justify the lack of precise surfaces in this application. The problem is, once you start working with computer modeling, you realize how simplified the other parts are. I would love to model a better detailed, correctly sized brake cylinder to go along with this valve, and it occurs to me that it would be really cool to also include the branch pipe with its dirt collector and cut-out cock. Problem is, I'm not willing to build models that look like they were done by Georges Seurat, where solid surfaces dissolve into thousands of little dots.

Several people have been a bit down on Shapeways, mentioning broken parts. Meanwhile, Shapeways has apparently just revised their minimum cross section requirements upward, obviously in an attempt not be responsible for failures when designers attempt to push the envelope. The problem I'm seeing, however, doesn't relate to minimum cross section (OK, so I can't include the brake pipe) but rather to layer thickness and surface resolution. The various machines I've researched that have a build envelope the size that Shapeways offers have a minimum layer thickness of 50 microns... essentially .002". Some systems are now claiming 27 microns, a bit over .001", but have build envelopes of only about one cubic inch. The problem is, .002" is clearly visible on an HO scale part; I've used that dimension for lap seems (although I prefer .003", to be sure it doesn't get filled with paint). I'm not sure that .001" is going to be much of an improvement. When the systems get down to 10 micron layers, I think we'll have something. I don't see why it isn't possible; I doubt 2-D printers lay down much more ink than that, but build time, and cost, is going to go up by a corresponding amount.

It will be interesting to see what the next couple of years brings.

Having built 20+ P2K Greenville gons, I have a small supply of leftover parts. Anyone
want some P2K drop-doors? (There are two sets in each kit.)

I think either Detail Associates or Details West makes a very nice lever hand brake, but
it may be too modern for the steam era. They are commonly applied on modern flat cars.

Does Walthers make the parts sprue for the P2K Greenville gon available as a separate item?

The two hand brakes are a Klasing 700-ish thing and an extremely rare Ajax lever hand brake of which I have only seen one in more than 30 years of looking.

Bruce,

Sorry, my statement was too general, What I ment to say is that kits are still listed by, Scale, Rail Road Name, and Kit number, as the previous website does. In other words, there are no search options etc. added. The Plus is that it works with Browsers other than IE. The Functioning links to dealers are a plus also.

Re: Off Topic--Shuttle

Jared,

The Marriott does not have s shuttle that goes to and from the airport. I asked them when I made my reservation as I had several friends that were thinking of attending the meet. Their response was that the shuttle would only operate within the five mile radius of the hotel.

Your choices are those which the guys have mentioned in response to your email. If you take the El into Chicago to Union Station, you can get the Metra local out to Naperville and the cost is $10 roundtrip. If you are a senior, then it is $5 roundtrip.

Re: Flat car weights for Chad Boas Resin bodies

Jim -

I worked with a guy who was the chief freight car person for the T&NO working in the Hardy Street shops in Houston starting in the late 1950's. He related an incident (in our time period) where there were repeated derailments on a particular train in East Texas. An investigation revealed that the everyday makeup of the train itself was the cause - heavy sulfur gons at the end of the train were running up against empty flats at the front of the train. This was in rolling country. The cars would derail after cresting a hill. Train handling was/is apparently challenging in such country. There were 1-1/2% grades (momentum gradients) up and down the hills, but they were very short, and slack action from train handling was a partial cause. This was an individual situation, and was not common.

From a modeler's standpoint, I like to place an empty flatcar just ahead of the caboose to show off the workmanship on the front of the caboose!

Tim O'Connor makes an excellent point regarding car placement in trains that are encompassed by this list (pre-1960). String-lining was a non-concept in the era we are concerned with. In fact, I am unaware of it being an official FRA derailment cause as late as the 1980's.

The factors that caused modern (post-STMFC) standards have more to do with factors like high-strength drawbars, high-adhesion locomotives, etc. All of which are beyond the scope of this list as Mike has often articulated.

I happen to be a recently retired railroader with 41 years of service. When I started in 1970, there were relatively few car placement restrictions (I would list some, but that would risk time in moderator's prison).

My point is that after reading literally thousands of special instructions in timetables, I've found little in the way of train make-up restrictions....

Re: Tangentially about freight cars but really about signaling

Dave Nelson
 

Richard, your description was different from Jim Wolf's who mentioned when a
train had *cleared the main* by going into industrial track they would need
permission to re-enter it. I took your example as one where the main had
not been cleared while working the industry. I imagine both examples are
correct for what was described.

I expect physical model railroads seldom have enough length in industrial
track to allow for a train to clear the main so in that realm it's a moot
point. For "virtual layouts" (what I operate on using software) there is no
compression and so there are plenty of situations where the main can be
cleared in order to spot freight cars. I guess those situations should be
thought of sort of as a-yard-w/o-a-yardmaster -- places where you can't come
out w/o first getting clearance.

Dave Nelson

-----Original Message-----

That's not quite what I was describing, Dave. At Rivera, a crew that wanted
to access the team track had to get the dispatcher to unlock the switch so
they could drop off one or more cars, pick up one or more cars, or both.
When they had finished their work, they would phone him again to re-lock the
switch.
