Or, you can just try to match actual prototype paint chips. https://www.flickr.com/photos/timboconnor/17098035956/ Putting a label on a bottle does not make it accurate. Tru-Color is known to sell the

Dave, That could be the arcane question of the month, if not the year. As I'm sure your are aware, this isn't readily found. Some values can be picked up in reading track-train dynamics studies and

On a bit more thought, perhaps the Acela moves its center of gravity sideways to accomplish this feat. Since the cars tip, perhaps the center of gravity really can be moved enough to make the kind of

I read this in the (1947) article cited: "Amtrak’s 150-mph (241-km/h) Acela creates its own bank angle by tilting up to 4.2 degrees. If the Acela is operating on a curve whose out-side rail is

Tru-color makes two versions of this--one for pre-1945 cars and one for post-1945. I have used their paint and it is great--it sprays perfectly right out of the bottle and dries glossy for

Probably old news but need some ATSF freight car red. Any help here about brand and/or mix that might get me close. Need to do touch up work on Walthers wood cabooses. Just not sure what is

Not trade literature, but a 1947 Scientific American article http://www.scientificamerican.com/article/the-physics-of-disaster/ Tim O'Connor I've never seen a discussion of this in the traditional

I think, back in the days of natural pigments mixed in naturally polymerizing oils such as linseed oil, that lampblack in oil was considered a better and longer lasting coating for metal. Oxide

The recent covered hopper discussion makes me wonder why many railroads painted their freight cars with 2 different color paints. Why not just one? Was black paint cheaper? Black house cars

The car standards for the La Mesa Model Railroad Club are by far the most stringent standards that I'm aware of, and I pasted in the center of gravity standard in answer to your question. I.

Presumably consideration was also given to the fact that the carbody.and trucks were only held together by center pins, although there were pads on both sides of the bolsters which could support

A lot lower on a flat car than a house car, with a gondola somewhere in between. Seriously, the mass distribution propoerties vary not only by car type but by construction. The trucks were generally

John, SIG, ie Special Interest Group, is a NMRA term/phrase. There is an application and guidelines through the NMRA for becoming a SIG. Yahoo Groups are an entirely different animal, so to speak.

There is a yahoo group for the Layout Design SIG look for ldsig in the groups. There was also a large layout yahoo group at one time, I'm not sure if it is still active but you could under large

And conversely, the Soo Line never adopted gray, their cement cars remained FCR their entire lives. Dennis Storzek

Sorry. When I said "SIG" I meant generic special interest groups, not necessarily NMRA. I looked around here but only could find a Small Layout Group. I could have sworn that there was a general

Branchline used to sell them separately. I would check with Atlas (under parts) to see if they are still carrying them. My understanding was that Atlas acquired all the Branchline rolling stock AND
